45+1.99x=68.88
Subtract 45 from both sides
1.99x = 23.88
Divide both sides by 1.99
X=12

Amount owed for movies =total amount owed - amounts charged by cable company
Amount owed for movies =68.88-45=23.88

Number of movies rented=amount owed for movies divided by amount per movie
Number of movies rented =28.88 divided by 1.99=12
Therefore you rented 12 movies

On a rectangle hyperbola, if one point is (2,3) and y varies inversely to x, find y when x is 6

s344n2d4d5 [400]

<span>The graph of y against x in inverse proportion is a rectangular hyperbola but I don't see at all how this knowledge/observation is any help in solving the problem.

Inverse proportion means that as x doubles y will halve and the equation is xy = k where k is some number. A good example of inverse proportion is speed and time taken over some fixed distance. In this case x could represent the speed (mph) and y the time (h) and then k is the distance in miles.

Since we know y=3 when x=2 we have xy = 6. Now it's easy to see when x=6 y=1.</span>
