If f(x)=x^3 and g(x)=2x+7 when g(x)=-5

Assume that y varies inversely with x. if y=1.6 when x=0.5 find x when y=3.2

Mr. jones determined that the equation y = 98 - 16/5 x could be used to predict his students' unit test scores, based on the number of days, x, a student was absent during the unit. what was the meaning of the y-intercept of the function? (by the way the 16/5 is a )
