If y varies inversely as x and when then when
Webthe formula for inverse variation is y = k/x. solve for k and you get k = xy. k is the constant of variation. it always remains the same. what this means is, if you multiply x by some factor, you need to divide y by the same factor. for example, let x = 4 and y = 8 the constant of variation is 4 * 8 = 32 WebAnswer (1 of 4): So defining the question: y(x^1/2) = 15x sqrt 9 = 45 so 45/9=5 5^2 = 25. So x=25 when y=9
