### Re: A quick question

Toggle the option, and look at the timestamps on the posts within a thread. In one ordering, it's "newest message on top"; in the other, it's "oldest message on top".

### Re: Re:

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...

### Re: Re:

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...

### Re: Percent Problem

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?
Yes, but it took me forever to figure it out.

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...

### Re:

Your instructor might prefer that the slope-intercept form be stated as:

. . . . .$y\, =\,2x\, -\, 2$

...but your solution and method are fine!
