The volume of a gas v held at a constant temperature in a closed container varies inversely with its pressure p. if the volume of a gas is 900900 cubic centimeters when the pressure is 500500 millimeters of mercury (mm hg), find the volume when the pressure is 450450 mm hg.

Graph the line that represents a proportional relationship between d and t with the property that an increase of 33 units in t corresponds to an increase of 44 units in d. what is the unit rate of change of dd with respect to t? (that is, a change of 11 unit in t will correspond to a change of how many units in d? )
