Answer



A relation is shown in this

table. Which statement

about the relation is true?

A. It is a direct variation because y = -2.5x + 12.5

B. It is an inverse variation because y = -2.5x + 12.5

C. It is a direct variation because 10 = xy

D. It is an inverse variation because 10 = xy


Answer

D. It is an inverse variation

An experiment is conducted on a container of gas

that is kept at a constant temperature.

~ When the pressure on the gas is 30 pounds

per square inch, the volume is 120 cubic

inches.

~When the pressure on the gas is 40 pounds per

square inch, the volume is 90 cubic inches.

Do the volume and pressure vary

directly or indirectly? Why?


AnswerThe volume of the gas

varies inversely with the pressure because

vp = 3,600..



Assume that x and y vary inversely.

If x = 3 when y = 6, find x when y = -8.
