The length of time a bag of cat food lasts varies inversely with the number of cats. If the bag of cat food will feed 5 cats for 10 days, how long will it feed 10 cats?

• 50 days

• 5 days

• 1/2 day

• 1

Answer explanation

You have to find first the k using the equation k=xy. The number of cats is x and the number of days is y. When you multiply x and y, you will get 50 as the value for k. To get the number of day, use the equation y=k/x and substitute the values, thus y=50/10=5 days.

Are these two lines parallel, perpendicular or neither?
y = -1/3x - 5
y = 1/3x + 2

• Parallel

• Perpendicular

• Neither
