Determine the vertex of each of the following parabolas by averaging the ‑intercepts. Then write each function in graphing form.

29 mil

step-by-step explanation:

what i would say the best answer is a. 40.5

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

30,40,50 is correct answer
