What is an equation?

A mathematical statement made up of two expressions joined by an equal sign is known as an equation. 3x - 5 = 16 is an example of an equation. We get the value of the variable x as x = 7 after solving this equation.

Given that:

Shirts By Sam

The cost of 10 shirts is $127.5

The cost of 15 shirts is $168.75.

Assume the equation that represents total cost is y = ax+b

Putting x= 10 and y=127.5 in y = ax+b:

127.5 = 10a+b.....(i)

Putting x= 15 and y=168.75 in y = ax+b:

168.75 = 15a+b.....(ii)

Use elimination method to solve equation (i) and (ii).

Subtract equation (i) from (ii)

15a+b = 168.75

10a+b = 127.5

____________

5a = 41.25

a = 8.25

Putting a=8.25 in equation (i)

127.5 = 10×8.25+b

b = 40

The equation is y = 8.25x+40.

Might T Shirt

The cost of 8 shirts is $137

The cost of 12 shirts is $163

Assume the equation that represents total cost is y = ax+b

Putting x= 8 and y=137 in y = ax+b:

137 = 8a+b.....(iii)

Putting x= 12 and y=163 in y = ax+b:

163 = 12a+b.....(iv)

Use elimination method to solve equations (iii) and (iv).

Subtract equation (iv) from (iii)

 8a+b = 137

12a+b = 163

____________

4a = 26

a = 6.5

Putting a=6.5 in equation (iii)

137= 8×6.5+b

b = 85

The equation is y =6.5x+85.

The solution of the system of equations:

y = 8.25x+40 .....(vi)

y =6.5x+85   ......(vii)

Use substitution method to solve equations (vi) and (vii).

Subtract equations:

8.25x+40 - 6.5x-85=0

1.75x - 45 =0

x = 45/1.75

x = 25.71

Putting x = 26 in equations (vi) and (vii)

y = 8.25×26+40 = 254.5

y = 6.5×26+85 = 254

Putting x = 24 in equations (vi) and (vii)

y = 8.25×24+40 = 238

y = 6.5×24+85 = 241

Angle B= 27, a=28ft, b=18ft solve for measurement(s) of angle c

Answers

Answer: In a triangle, the sum of the angles is 180 degrees. Therefore, if we know two of the angles, we can use this property to find the measure of the third angle.

In this case, we are given angle B = 27 degrees and we want to find the measure of angle C. We can use the following equation to find angle C:

Angle B + Angle C + Angle A = 180

27 + Angle C + 90 = 180

Angle C = 180 - 27 - 90

Angle C = 63 degrees

Additionally, we can use the Law of Cosines to find the measure of angle C.

c² = a² + b² - 2ab * cos(C)

c² = 28² + 18² - 2 * 28 * 18 * cos(C)

c² = 784 + 324 - 1008 * cos(C)

c = √(1108 - 1008*cos(C))

We know that cos(C) = (a² + b² - c²) / 2ab

cos(C) = (784 + 324 - c²) / (22818)

We can substitute the value of c² that we obtained from the first equation and find cos(C) and thus angle C.

So the measure of angle C is 63 degrees.

If a number is completely divisible by another number then the quotient will be a whole number and the remainder will be zero.

As the name suggests, divisibility tests or division rules in Maths help one to check whether a number is divisible by another number without the actual method of division.

Finding the product of two or more corresponding integers is done mathematically through the action of multiplication. It is frequently represented by the letters "x" or "*." In order to discover the result of multiplication, a multiplicand, also known as the multiplicand, is multiplied by a multiplier, also known as the multiplier. The result of the two integers, for instance, is 56 if the multiplicand and multiplier are both 8. A multiplication process always yields a greater number as the outcome than either of the initial factors. Multiply is also used to describe the process of adding a number to itself a certain number of times, as in "7 multiplied by 3 equals 21."

How to solve?

For instance, if the multiplication error is 8 x 7 = 56, then the matching division error  56/8 = 7, demonstrating that the result of the division is the other component that was used in the multiplication.

This connection is true for every multiplication and division problem as long as the numbers are utilised consistently in both operations.

To prove the converse of the Pythagorean theorem, we can define a right triangle, Response area, with sides a, b, and x. Then, we will show that if ​△ABC​ is a triangle with sides a, b, and c where a² + b² = c², then it is congruent to △DEF and therefore a right triangle.

By the Pythagorean theorem, because ​△DEF​ is a right triangle, a² + b² = x².

If ​​a² + b² = x² and a² + b² = c² ​​, then c² = x². Further, since sides of triangles are positive, then we can conclude that ​c = x​. Thus, the two triangles have congruent sides and are congruent.

If ​△ABC​ is congruent to a right triangle, then it must also be a right triangle.

An equation in standard form with an x-intercept of 5 and a y-intercept of -4 is,

⇒ 5x + 4y = 20

What is an expression?

Mathematical expression is defined as the collection of the numbers variables and functions by using operations like addition, subtraction, multiplication, and division.

Given that;

The x - intercept = 4 ,

So, ( 4,0) is a point on the line.

And, The y - intercept = 5,

So, ( 0, 5) is a point on the line.

Now, Slope of the line passing through the point (4, 0) and (0, 5) is,

⇒ m = (5 - 0) / (0 - 4)

⇒ m = - 5/4

So, The slope intercept form of an equation is,

⇒ y  = mx + b

Where, m = slope and b = y- intercept.

Hence, We get;

⇒ y = - 5/4x + 5

We know that;

An equation in standard form is,

What do you mean by Coordinate Plane?

A coordinate plane, also known as a Cartesian plane, is a two-dimensional surface that is used to graph points, lines, and shapes. It is named after the mathematician René Descartes, who is credited with inventing the system in the 17th century.

The coordinate plane is divided into four quadrants by two perpendicular lines called the x-axis and y-axis. The point where the two axes intersect is called the origin and is assigned the coordinates (0,0). The x-axis runs horizontally and is used to measure values along the horizontal (or "x") direction, while the y-axis runs vertically and is used to measure values along the vertical (or "y") direction.

Each point on the coordinate plane can be represented by an ordered pair of numbers, called coordinates, that indicate its position in relation to the x- and y-axes. The coordinates of a point are written as (x, y), where x is the point's distance from the y-axis and y is the point's distance from the x-axis.

The equation that represents the comet's orbit is:

Alex is applying for positions at two different electronic stores in neighboring towns. The first job offer is a $200 weekly salary plus 5% commission on sales. The second job offer is a $75 weekly salary plus 10% commission.

Answers

The  amount of sales at which Company A's offer is the same as Company B's is  $600

How to calculate the amount?

The given parameters that will help us to understand the question are

Company A:

Base = $200

Commission = 10% of sales = .1*S

A = .1S + 200

Company B:

Base = 400

Commission = .05*S

B = .05S + 400

We're looking for the point where they're equal.

200 + .1S = 400 + .05S

Multiply by 100 to get rid of decimals

20000 + 10S = 40000 + 5S

Subtract 20000 from both sides

10S = 20000 + 5S

Subtract 5S from both sides

5S = 20000

Divide both sides by 5

S = 4000

So, at $4000 sales, the two jobs pay the same.

You have to always check your work. This can be done by plugging the values into the basic equations and determining if they check. Or we can graph the two lines and see where they cross.

Company A:

200 + .1(4000) = 200 + 400 = 600

Answers

f + s = 10

| f - s | = 18

-------

This means that:

f = 10 - s

And also that:

| f - s | = 18

(f-s)²=18²

f²- 2sf + s² = 324

But f=10-s

So...

(10-s)² - 2s(10-s) + s² = 324

(10-s)(10-s) - 20s + 2s² + s² = 324

100 - 20s + s² - 20s + 2s² + s² = 324

4s² - 40s + 100 = 324

4s² - 40s + 100 - 324 = 0

4s² - 40s - 224 = 0

1/4 * (4s² - 40s - 224) = 1/4 * 0

s² - 10s - 56 = 0

(s-14)(s+4)=0

So s can be either 14 or -4.

When s = 14, f = -4.

When s = -4, f = 14.

The 3 action sequence is a great tool for breaking down complicated tasks into more manageable parts. It can help you stay on track and keep focus when working on a task. It can also be used to create a timeline for completing a task, or to create a checklist of items that need to be completed.

Step-by-step explanation:

The figure below shows a circle with center J, diameter FG, and tangent YQ. Which of the angles must be right angles? select all that apply.

Answers

The angle which would be tangent  a 90 degree in the given diagram would be ∠JYQ, ∠JYW  , ∠FYG and ∠FHG

What is a tangent in a circle?

A circle's tangent is a single-pointed line that intersects the circle. The point of tangency is the location where the circle and the tangent cross. The circle's radius, where the tangent touches it, is perpendicular to it.

Therefore, JY is perpendicular to QW which means

∠JYQ=∠JYW=90 degrees

Since, J is the center of circle and GF is diameter, there is a theorem which says that angle substended by diameter at any point of circle is 90 degree.

Therefore, ∠FYG =∠FHG=90 degrees.

Hence, ∠JYQ, ∠JYW  , ∠FYG and ∠FHG are all the equal to 90 degree.

Square each binomials and place them into perfect square trinomial form, then subtract the trinomial

1 (x + 3) 2 - (x - 4) 2

2 (7b2 - 7) 2 - (2b2 - 11) 2

3 (5ab2 + 3) 2 - (6ab2 - 7) 2

Answers

The results of subtractions between perfect square trinomials are listed below:

(x + 3)² - (x - 4)² = 14 · x - 7 (7 · b² - 7)² - (2 · b² - 11)² = 45 · b⁴ - 54 · b² - 72 (5 · a · b² + 3)² - (6 · a · b² - 7)² = - 9 · a² · b⁴ + 114 · a · b² - 40

How to simplify subtractions of perfect square trinomials

In this problem we have three cases of subtractions between two perfect square trinomials that must be simplified. According to algebra, perfect square trinomials can be expanded by means of the following definition:

(a + b)² = a² + 2 · a · b + b²

Where a, b are real constants.

The procedure is summarized below:

Expand the perfect square trinomials.Add and subtract similar terms.Arrange the resulting polynomial in standard position.

Case 1

(x + 3)² - (x - 4)²

(x² + 6 · x + 9) - (x² - 8 · x + 16)

x² + 6 · x + 9 - x² + 8 · x - 16

14 · x - 7

Case 2

(7 · b² - 7)² - (2 · b² - 11)²

(49 · b⁴ - 98 · b² + 49) -  (4 · b⁴ - 44 · b² + 121)

49 · b⁴ - 98 · b² + 49 - 4 · b⁴ + 44 · b² - 121

45 · b⁴ - 54 · b² - 72

Case 3

(5 · a · b² + 3)² - (6 · a · b² - 7)²

(25 · a² · b⁴ + 30 · a · b² + 9) - (36 · a² · b⁴ - 84 · a · b² + 49)

25 · a² · b⁴ + 30 · a · b² + 9 - 36 · a² · b⁴ + 84 · a · b² - 49

- 9 · a² · b⁴ + 114 · a · b² - 40

hi who know how to do this question?can someone help me solve​

Answers

Answer:

Below

Step-by-step explanation:

f(1)    -  2 = a(1) + b

        - 2 = a + b             (1)

f(5)     10 = a (5) + b

          10 = 5a + b            (2)

Multiply first underlined equation by -5  to get

      10 = -5a  - 5b       add this to the second equation (this will eliminate 'a')

      20 = - 4 b       so   b = -5

   

then the first equation becomes   - 2 = a +  (-5)

             which shows a = 3

so your function is just    f(x) = 3x  -5

The solution for given equations are: z = 4, b = -12, w = 5, c = -11

What is mean by equations? How can be solve variables?

An equation is a mathematical statement that expresses the equality of two expressions.

Variables are symbols or letters used to represent unknown values in equations.

To solve for a variable, one must first isolate the variable by performing the same operations on both sides of the equation until the variable is alone on one side of the equation.

For example, if the equation is 2x + 4 = 10, the first step would be subtracting 4 from both sides of the equation to get 2x = 6. The next step would be to divide both sides of the equation by 2 to get x = 3. This is how one would solve for the variable in this equation.

According to question:-

A. 3(7z-6)=-(-18z+6)

21z - 18 = 18z - 6

3z = 12

z = 4

B. -8b+2(-5b-2)=212

-8b - 10b - 4 = 212

-18b - 4 = 212

b = -12

C. 4/5w+5 = 1/5w+8

4/5w-1/5w = 8-5

3/5w = 3

w = 5

D. (-c-8)-(7c-6)= 18c+284

-c-8-7c+6 = 18c + 284

18c + 8c = -2-284

26c = -286

c = -11
