PLEASE HELP Find the coordinates of the orthocenter of the triangle with the given vertices. Slope formula: y2−y1 x2−x1 Point-slope formula: y−y1=m(x−x1)

A (-1, 2) B(9, 2) C(-1, -3)

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

part a: 1.08

part b: 27.59
