Let f(x) = 2x^2 + 7x - 5 and g(x) = -8x^2 - 3x + 5. what is g(x) + f(x)? sorry to be a burden but i just can't think straight, some would be appreciated.

-6x^2 +4x

Step-by-step explanation:

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
