Executive Auto Rental charges a fixed daily rate and a mileage charge. One customer rents a car for one day and drives it 125 miles. His bill is $65.75. Another customer rents a car for one day and drives 265 miles. Her bill is $109.15. Write the linear equation relating miles driven and total cost. (Let y represent the total cost and x represent the number of miles driven.)

$20.01

step-by-step explanation:

the sale price is (1.00 - 0.77)($87), or 0.23($87), or $20.01.

17.08

correct me if i am wrong.

guess at question:

a vertical line intersects the graph of g(x,y) = 0 at two points. what conclusion follows about the function f(x) implicitly defined by g(x,f(x)) = 0?

the domain of f(x) cannot include the x coordinate of any such vertical line.

informally, f(x) is not a function, and

g(x,y)=0 cannot be solved for y uniquely.

the relation r = {(x,y) such that g(x,y) = 0} is a function if

for all (a,b) ∊ r and (c,d) ∊ r, a=c implies b=d.
