Rosa has a goal of running a totalof 100 miles this month. each day that she ran she ran 5 miles. which expression could rosa use to determine how many miles she has left to run after d days. a 100-5d b 5d+100 c 100 over 5d d 5d

x = 23.78

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. : )
