Si a un producto se le rebajado un 15%, y una vez rebajado, se le aplica otra rebaja del 20% ¿cual es el porcentaje que se le ha rebajado sobre el precio inicial?

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. : )

the answer is 8/21

hope this

i think it is c hope that
