A number is multiplied by 4, That result is added to 12. The final number is 40. What is the original number.
A. 2
B. 7
C.13
D.22

Step-by-step explanation:

the answer is 7

14

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. : )
