How is this problem different from the previous problems we've done?

kayders1997 · Answer

No because when your doing inverse problems your multiplying and dividing

mathmale · Answer

Please let Ms-Brains answer that question.   Thanks.  Note:  My question was not a Yes or No question.

ms-brains · Answer

Oh, so that would make  D as the correct answer?
I don't see how A or B could be the correct answer. @kayders1997

mathmale · Answer

I insist you need to determine how this problem differs from previous ones and then to act accordingly.

mathmale · Answer

The more work y ou show, the better the chances that you and I will understand your thinking.

ms-brains · Answer

I know it's a different problem because the inverse variation, and the quadratic variation.

ms-brains · Answer

I'm pretty sure the correct answer is D, so I'm going to close the problem. :)

mathmale · Answer

Right.  So the model used before won't succeed here.

For direct variation, the model is the one we used earlier:  y=kx.

What is the model for inverse variation?  The meaning of "inverse variation" here is that if the independent variable (x) increases, the dependent variable (y) decreases.
