Okay, so your book is using the same definition as the document at the link. It's substitution, but you solve for "y=" or "x=" in both of the equations, instead of just one. Then you set the other side of the two equations equal to each other. In other words, instead of getting "y=" for one equatio...

I've never heard of the "comparison" method. How does that work? Can you give an example from your book, or maybe a link? (All I could find is a PDF worksheet that makes it look like "comparison" is just a form of "substitution", where both equations are already solved for one of the variables.) Th...

Yes, but it took me forever to figure it out.Check your answers. Do you have a number of girls that is 20% more than the number of boys? Find 20% of the boys, and then find 80% of this amount. Does this equal 48?

In the user control pannel, there is an option that says "display topics direction by ascending or descending". What does that mean?

The number of female students who buy lunch is 80% of the number of male students who buy lunch, but there are 20% more female...

Anyone have any ideas of real life examples of where it would be necessary to use a radical expression and a rational exponent. I'm looking for two different examples; one for each. Thanks, Lisa One example of a radical expression (yes, it is a little confusing) is the rate of diffusion of a gas. W...

Is there any difference?Your instructor might prefer that the slope-intercept form be stated as:
