I know you are reading this answer the question.

C. x = 3

Step-by-step explanation:

When x = 3:

f(x) = x - 3 = 3 - 3 = 0

g(x) = - 1 = - 1 = - 1 = 1 - 1 = 0

0 = 0

the correct answer is you spend $55.78 more in a brand store that buy ing in a normal store.

step-by-step explanation:

brand = spend   $ 135.85 total

store = spend $80.07 total

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. : )
