Ikeep getting -5/3 but it's not right.

replace x = 7  into the equation

f(7) = 7/9 - squared root (7-3)

f(7) = 7/9 - squared root (4)

f(7) = 7/9 - 2

f(7) = -11/9

f(7) = -1.22

; )

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 .
