Diane has rented a movie from Cine-Flix and is returning it late. The equation y = 2x + 4 represents the cost y (in dollars) of renting a movie after x days of late charges. Graph the equation and determine how much it will cost Diane after 3 days of late charges.

Respuesta :

y = 2x + 4
x : days of late charges
y : cost

So you would have to substitute 3 into x because Diane is 3 days late.

y = 2x + 4
y = 2(3) + 4
y = 6 + 4
y = 10

It would cost $10. 

Answer:

$10

Step-by-step explanation:

y=2x+4

x=3

y=(2×3)+4

y=6+4

y=10

Therefore she spent $10 on the rented movie.
