7y2 + 14y2 + 4y + 7 + 14y2 + 17 + 10y + 4y

35y2 + 18y + 24

Step-by-step explanation:

7y2 + 14y2 + 14y2 = 35y2

4y + 10y + 4y = 18y

7 + 17 = 24

35y2 + 18y + 24

hope this ! (:   mark me as brainliest if you can

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
