In a cyclic quadrilateral ABCD, AD is parallel to BC. The bisector
of <BAD meets BC at E and the circle at F. Prove that:
EF=FC ( BF - DF

1 + (6 / x - 1)

step-by-step explanation:

divide using polynomial division.

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
