Find the discriminant and use it to determine how many solutions there are for the equation.
2h2+ 7h+ 4= 0

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

i believe a. 12x≥120 is the answer
