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.

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? - April 17th 2008, 07:50 PMJen
