Agroup of functions in the form y = a 0 x n + a 1 x n-1 + a 2 x n-2 + + a n-1 x + a n where a 0, a 1, numerical coefficients and n, a positive integer, is the exponent of the variable x. the number n then becomes the degree of the polynomial.

answer: b.36 feet

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
