Solve:if y varies directly as the cube of x and if x = 125 and x=5, find x when x=729

Step-by-step explanation:

y varies directly as the cube of x:

this means y is proportional to the cube of x

y α x^3

or

y = cx^3

Where 'c' is some constant.

plug in the given x and y and solve for c, then you can plug in c and the new x and solve for y.
