G+2.64=12.15 solve for g

9.51

Step-by-step explanation:

12.15-2.64=9.51

because if you subtract you answer from your second or first number to add it up you get the other answer.

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. : )
