Answer:

y = 4x+4

Step-by-step explanation:

Using the coordinate point (1, 8) and (2, 12) from the table

Slope m = 12-8/2-1

m = 4/1

m = 4

Get the intercept

Substitute m = 4 and (1, 8) into y = mx+c

8 = 4(1) + c

8 - 4 = c

c = 4

Get the required equation

y = 4x + 4

Hence the required linear equation is y = 4x+4

Answer:

x = -1 , y = -1

Step-by-step explanation:

We have system of equations and are asked to solve them.

We are looking for x and y, since both equations start with y, we can plug one to the other.

y = 5x + 4

y = 7x + 6

5x + 4 = 7x + 6

Now isolate x byitself to get x :

5x + 4 = 7x + 6

Subtract 4 from both sides :

5x = 7x + 2

Subtract 7x from both sides :

-2x = 2

Divide -2 by both sides :

x = -1

Now that we know what x is, we can substitute it into the equations seapraretly.

y = 5(-1) + 4

y = 7(-1) + 4

y = -5 + 4

y = -7 + 6

-5 + 4

-1

-7 + 6

-1

Therefore, both x and y equal -1

Answer:

Step-by-step explanation:

Prism A Volume

The Column of Prism A = Base (Area) * Height.

I think you have to assume that the triangle is a right triangle.

Area of the triangle = 1/2 * 9 * 7

Area of the triangle = 1/2 63

Area of the triangle = 31.5

Volume of the Prism = area of the triangle * thickness

Volume of the prism = 31.5 * 4

Volume of the prism = 126 m^3

Prism B = L * w * h

Prism B = 8 * 8 * 2

Prism B = 128

Prism A has the least volume by just a little.

Answer:

Prism A has the least volume

Step-by-step explanation:

Answer:

P [ 40000 ≤ X ≤ 45000 ] =  0,02773    or  2,8 %

Step-by-step explanation:

P [ 40000 ≤ X ≤ 45000 ]  = ?

To find the probablity    P [ X ≤ 40000 ] =  ?

z(s)  = ( X - x ) / σ

z(s)= ( 40000 - 6000 )/ 8300

z(s) =  -20000/8300

z(s) ≈  - 2,41

Then

from z-table we find P [ X ≤ 40000] =  0,00820

Now again:

For  P [ X ≤ 45000 ]

z₂  = ( X - x ) / σ

z₂ =  ( 45000 - 6000 ) / 8300

z₂ = - 15000 / 8300

z₂ = - 1,8072

z₂ ≈ 1,81

From z - table

For  P [ X ≤ 45000 ] =   0,03593

Then:

P [ 40000 ≤ X ≤ 45000 ] = 0,03593 - 0,00820

P [ 40000 ≤ X ≤ 45000 ] =  0,02773    or  2,8 %

Answer:

5

Step-by-step explanation:

We have an equation and are asked to find the input of x when y = 7.

The output = y = 7

The input = x

7 = 2x - 3

2x - 3 = 7

We need to find a number that multiplied by 2 which then is subtracted by 3 equals 7. We can use the backwards method  to solve our answer.

2x - 3 = 7

7 + 3 = 2x

10 = 2x

Solve for x by dividing 2 from both sides :

x = 5.

Therefore, you would need an input of 5 to get 7 as the output.

Proof :

2(5) - 3 = 7

10 - 3 = 7

Answer:

x = 5

Step-by-step explanation:

Remark

This is a fancy way of asking you what is the value of x when y = 7

Equation

7 = 2x - 3

Solution

7 = 2x - 3                  Add 3 to both sides

7 + 3 = 2x                 Combine the left.

10 = 2x                      Divide by 2

2x/2 = 10/2

x = 5

Answer:

Value of x = 7.0 units.

Step-by-step explanation:

Given the trigonometric equation

[tex]\tan \left(25^{\circ }\right)=\frac{x}{15}[/tex]

Switch sides

[tex]\frac{x}{15}=\tan \left(25^{\circ \:}\right)[/tex]

Multiply both sides by 15

[tex]\frac{15x}{15}=15\tan \left(25^{\circ \:}\right)[/tex]

Simplify

[tex]x=15\tan \left(25^{\circ \:}\right)[/tex]

∵ tan (25) = 0.46630

Thus,

x = 7.0     (rounded to nearest tenth)

Therefore, value of x = 7.0 units.

Answer:

a) y=8x+12

b) $52

Step-by-step explanation:

for a)

the linear cost of this equation is 8, since is asks this amount per hour. The constant is 12, a one time fee. to form the equation, you would use the formula y=mx+b, and substituted in with the given, you get y=8x+12.

for b)

in b, it asks for the cost of renting the boat when x=5, renting the boat for 5 hours. all you have to do is plug in 5 in place of the x in the equation:

y=8x+12

y=8(5)+12

y=40+12

y=52

Answer:

a) x = 69°

b) y = 69°

Step-by-step explanation:

a. Given that AB and CD are parallel lines, therefore:

x = 69° (alternate interior angles are congruent to each other)

b. y + 111° = 180° (consecutive interior angles are supplementary)

y = 180° - 111° (substraction property of equality)

y = 69°
