Which function represents a reflection of f(x) = 3/7(2)^x over the x-axis? [ / = fraction] A. g(x) = -3/7 (2)^x
B. g(x) = 3/7 (-2)^x
C. g(x) = 3/7 (1/2)^-x
D. g(x) = 7/3 (2)^-x

B is the right answer for this one

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
