The area of the rectangle is 66m^2, and the length of the rectangle is 7m less than three times the width. find the dimensions of the rectangle.

length:
width:

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

a reflection across the x axis and a 90 degree rotation left and right.
