Evin proposes the following explicit formula for the amount of savings, a, as a functions of the number of weeks saved n. Is this formula correct? Test it! a(n) = 3n + 15

i think this could be a possible answer (1 / 84) -1

good luck! : d

step-by-step explanation:

when you realize that you dont know just realize i just took a test and im so smart

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. : )

-4, -2, 1, 4

step-by-step explanation:

domain = x values

range = y values
