Answer:
5) B
She inital pay $200 then ahs to pay 22.50 per play.
So Cost = 200 +22.5n
6) D

7) D
24 + 6 x = 120
6 x = 120 - 24
x = (120 -24) / 6
x = 16 Hours
8) D
When s = 0 Temperature is 50
When s = 5 Temperature is 0
When you plug in the values into Equation D the values work.
9)
Service Call= $50
Hourly = $25
Repair Cost = Service Call + 25 x Hour
y = 50 + 25x
When x = zero then y = 50
when x = 1 then y = 75
Plot two points:
(0,50) and (1, 75) then draw a straight line through those two points all the way up and down.
