A ball is dropped from the top of a building. It falls at a constant rate of 10 miles per hour until it bounces on the sidewalk and then bounces back up at a constant speed until it reaches the top of a building. a) Is this function linear or non-linear?

b) Explain why.

a

step-by-step explanation:

let y equal to

the total fare and x is the mile of taxi ride. so the equation is

y = 0.55x + 1.75

since susie has

$10 to spend for a taxi cab, so he can have

10 = 0.55x +

1.75

x = 15 miles of

taxi ride

so the system of

inequality is

10 < 0.55x +

1.75

x > 2
