find the variation constant and an equation of variation where y varies directly as x and y = 54 when x =x6

Answer 1

" y varies directly as x" ---> y =kx, where k is a constant.
if x= ?? , is that a typo? , then y = 54
plug in those two values into y = kx,
solve for k and put that back into the equation.

(if you mean x = x^6, then
54 = kx^6
k = 54/x^6

then y = (54/x^6) (x) = 54/x^5 )
