1. The paths of two dolphins playing in the ocean were recorded by some biologists. The first dolphin's path could be modelled by the equation h(t) = 2t4 - 17t³ + 27t² -
252t +232 and the second dolphin's path could be modelled by the equation h(t) =
20t3-200t² + 300t - 200.When was the first dolphin higher than the second dolphin?

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
