find an equation of combined variation 1.a varies directly as b and inversely as c. a=12 when b=4 and c=5 2.z varies jointly as x and y and inversely as w. z=100 when x=5,y=6,and w=3
An inverse variation can be represented by the equation xy=k or y=kx . That is, y varies inversely as x if there is some nonzero constant k such that, xy=k or y=kx where x≠0,y≠0
