Answer:

(2,-0.5)

Step-by-step explanation:

Answer: (2,-0.5)

Step-by-step explanation:

You need to find the difference between the x's and the y's, then divide by 2.

Step 1: Find the difference between the x's

5 + -1 = 4

Step 2: Find the difference between the y's

-4 + 3 = -1

Step 3: Divide both the results by 2

4/2 = 2

-1/2 = -0.5

Answer:

0,0

16,4

24,10

multiple both numbers by two and those should be the coordinates

Hey there!

=> n + 652 = 17 { Substract 652 from both sides}

=> n + 652 -652 = 17 - 652

=> n = 17 -652

=> n = -635

Therefore, N = -635

y=14

10y=140

Divide both sides by 10.

y=

10

140

​

Divide 140 by 10 to get 14.

y=14

The slope of a line perpendicular is -5/3 to the line whose equation is 6x-10y = 140.

The slope of a line is defined as the inclination of the line. It is denoted by m

Slope m = (y₂ - y₁)/(x₂ -x₁ )

Make the following equation in slope-intercept form:

y = mx + b

where m denotes the slope and (0,b) denotes the y-intercept (the point at which x = 0).

The given equation is:

6x - 10y = 140

-10y = - 6x + 140

Divided by -10 into both sides of the equation,

y = (6/10)x + 140/(-10)

y = (3/5)x -14

Here m = 3/5, b is (0,14)

The slope of this line is 3/5.

The slope of all of its perpendicular lines is (-1/m), which is the negative reciprocal of slope m.

Therefore, the slope of all perpendicular lines is (-5/3).

Answer:

If I read the question right, then the answer is -36.5.

Step-by-step explanation:

Like I said, only if I read the question right. I read it as

(-35) - 1.5.

If I'm wrong, then I'm sorry.

The product of (−35)∙(−1). (5) will be 105. It is obtained by multiplying the term one by one.

It is defined as the operation in which we do the addition of numbers, subtraction, multiplication, and division. It has basic four operators that are +, -, ×, and ÷.

We can utilize multiplication for a number of common tasks, such as figuring out how much it will cost to buy several identical things, calculating sales tax, and figuring out area and other geometric measurements.

It is given that,

=(−35)∙(−1).5

Multiply the term step by step as

=(−35)∙(−1).5

The multiplication of two negative terms gives a positive value.

=(35)5

=105

Thus, the product of (−35)∙(−1). (5) will be 105. It is obtained by multiplying the term one by one.

Answer:

  f(x) +g(x) = x^2 +x -20

  domain: all real numbers

Step-by-step explanation:

The sum of two polynomial functions is found by adding the terms of each function definition:

  f(x) +g(x) = (x -4) +(x^2 -16)

  f(x) +g(x) = x^2 +x -20

__

The domain of any polynomial is "all real numbers." The set of polynomials is closed to addition, meaning the sum of any polynomials is another polynomial. The sum, too, will have a domain of "all real numbers."

The factorisation of the polynomial [tex]2x^3+8x^2+3x+12[/tex] can be done as [tex](2x^2+3)(x+4)[/tex].

A factor of n is a number that when multiplied by another number gives us the number n.

In order to factorise the given polynomial, we need to take the common terms out, therefore, the factorisation of the given polynomial can be done as,

[tex]2x^3+8x^2+3x+12[/tex]

Take 2x² as the common term from the first two terms and 3 from the last two terms,

[tex]2x^3+8x^2+3x+12\\\\= 2x^2(x+4)+3(x+4)\\\\=(2x^2+3)(x+4)[/tex]

Hence, the factorisation of the polynomial [tex]2x^3+8x^2+3x+12[/tex] can be done as [tex](2x^2+3)(x+4)[/tex].

Answer:  B. a + (-b) = 7

Step-by-step explanation:

The answer is B. a + (-b) = 7. a + (-b) is the same thing with a - b.

A. a + b = -7

a - b = 7 means the differences of a and b is 7, choice A is talking about their sum, so it could not be true.

C. -a - b = 7

if you multiply -1 on both sides, you will get a + b = -7. Therefore, it will not be true.

D. b - a = 7

a - b = 7 means that a is 7 more than b. The choice d shows the opposite, which it states that b is 7 more than a. Therefore, it is not true.

Hi!

To find the surface area, we must first find the area of all of the faces and then add them together.

Because every face is the same size, the formula will be:

6(8 x 8)

6 represents the number of faces and 8 x 8 represents the formula to find the area of each.

6(8 x 8) =

6(64) =

384

The surface area of the cube is 384 square inches.

Answer:

a. x - cd = 0

b. d = 1 / 2

Step-by-step explanation:

d = 2

c = 7

a.

c is inversely proportional to d,

c ∝ 1 / d

This inversely proportional need to be removed by using a variation / variable.

Let the variable be " x ".

c = x / d

Multiply d on both sides,

cd = x

x = cd

Subtract cd on both sides,

x - cd = 0

Hence, the equation is " x - cd = 0 ".

b.

By using the equation,

x - cd = 0

Add cd on both sides,

x = cd

c = 17, d = 2

x = 17 * 2

x = 34

To find d, when c = 68.

x = cd

34 = 68 * d

Divide 68 on both sides,

34 / 68 = d

1 / 2 = d

d = 1 / 2

x^2+x
