8) Solve the system by substitution.
(9 pts)
5x + y = -10
4x = 7v = -8

5x + y = -10:

Slope = -10.000/2.000 = -5.000

 x-intercept = -10/5 = -2

 y-intercept = -10/1 = -10.00000

Step-by-step explanation:

we'll this would mean that the dunk tank and the bounce house are the same for 20 hours because the 2 represents that the two activities, and the 20 represents the amount of hours they both are. so with this said, it means that the answer is c. the costs for a dunk tank and bounce house are the same for 20 hours.

c.the costs for a dunk tank and bounce house are the same for 20 hours.

hope this .
