Answer:

y = -47

Step-by-step explanation:

To find the midpoint of two points, add them together and divide by 2

(y+33)/2 = -7

To find y, multiply each side by 2

(y+33)/2 *2 = -7*2

y+33 = -14

Subtract 33 from each side

y+33-33 = -14-33

y = -47

SOLVE USING ELIMINATION *20 POINTS*

V125BC [204]

1. No answer ( may be due to incorrect question)

2. x = -3

y = 4

3. x= 4

y = 2

4.x = -63/40

y= -19/20

Step 1

Multiply equation 1 by the coefficient of x in equation 2

Multiply equation 2 by the coefficient of x I'm equation 1

(after completing this step you will derive equation 3 and 4 )

Step 2

Subtract equation 4 from equation 3

Step 3

Divide both sides of the equation by the coefficient of y

Step 4

substitute your value for y in equation 1 or 2

(after this you will derive the values of x)

Note : This method is for the Elimination of x

I hope it helps

y = 80x - 60

Answer is B. y = 80x - 60

Double check:

When x = 1, y = 80(1) - 20 = 80 -60 = 20

When x = 2, y = 80(2) - 20 = 160 -60 = 100

When x = 3, y = 80(3) - 20 = 240 -60 = 180

When x = 4, y = 80(4) - 20 = 320 -60 = 260

When x = 5, y = 80(5) - 20 = 400 -60 = 340
