Just a couple of simple questions I'm having trouble on. 6. y is directly proportional to the square of x, and y = 48 when x = 4. What is y when x = 24? 10. y is inversely proportional to x, and y = 32 when x = 4. what is y when x = 18? Thanks.

Inversly proportional means, so if y is directly proportional to the square of x then, Then use your values given to solve for K. Hope that helps!
Thanks. What confused me was there were problems stating "y varies directly/inversely with x" and "y is directly/inversely proportional to x" What's the difference?
