Oceanside Bike Rental Shop charges 18 dollars plus 6 dollars an hour for renting a bike. Mary paid 66 dollars to rent a bike. How many hours did she pay to have the bike checked out? Write an equation then solve.

check the picture below.

well, the angle at the vertex d is clearly not a right-angle, let's check for the one at the vertex f which does look like,   however if it's indeed, that means ef is perpendicular to df, in which case their slopes will be negative reciprocal of each other.

so the negative reciprocal of the slope of ef is 1, however the slope of df is not 1, is 1/2, so nope, they're not perpendicular lines.

answer: just subtact the units and then add the non negative : happy to

step-by-step explanation:

sine

step-by-step explanation:

the answer is (-4,-4)

hope this ! : d
