The sum of a number and 9 is - 7

x = the number

x + 9 = the sum of a number and 9

8(x + 9) = eight times the sum of a number and 9

8(x + 9) = 7

8x + 72 = 7

x = (7 - 72) / 8 = -65 / 8

Step-by-step explanation:

where is the image?

step-by-step explanation:

b. y = 4x - 2

step-by-step explanation:

to find a parallel equation to an equation, make sure both equations have the same slope but different y-intercepts.

y = 4x + 1

4 = slope

1 = y-intercept

y = 4x - 2

4 = slope

-2 = y-intercept

they both have the same slope but different y-intercepts, so, b. is the correct answer.

and to check your work, you can graph both equations. : )
