Esboçe o gráfico e determine o zero das seguintes funções quadraticas: a) y=2x2 −8x+6
b) y=x2 −12x+35
c) y=−x2 +x+12
d) y=6x2 +x−1
e) y=3x2 −7x+2

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
