If you were in a geometry class, and this question was about the Pythagorean Theorem, then yes, A^2 + B^2 = C^2. But besides that I'm somewhat at a loss.
Also note, that "A^2 + B^2 =" , by itself like that, is not an example of
any problem. It's not a valid...

This is tough. It increases once, then decreases 3 times. Can you double check to make sure these are typed in the correct order? Also, it might be helpful if you provided the name of your class, and the names of the chapter/section you guys are on, when this problem was given to you...

The first part is totally correct, x + y = z + 3, awesome!
1. The formula for simple interest:
[ending amount] = [starting amount] * [Interest Rate] * [Time]
2. When given an interest rate in percent form, you need to convert it to decimal, and then add 1 to it, so that...

Hmm, the expression is 8xyz because there is no equal sign.
The other three:
2y = 4x-6
y = 5
x = -4
All three of the above are equations, but they are also linear functions as well, because there are no exponents on the x or y variables.
For example,
2y...

Put in other words, they are looking for a number, that when multiplied by 3, gives you 27. So 3 times what = 27?
This problem can be solved algebraically, but first I just want to state a few key rules of algebra.
1) any number divided by it self, equals 1.
(5 divided...

first add 9x to both sides, to get 9x -5x = 3
collect like terms, to get 4x = 3
then divide both sides by 4, to get x = 3/4
cheers!

I've downloaded my textbooks whenever I could in the past, but most of the time torrent sites don't have the book you need.
Give http://thepiratebay.sx/ a try, if that doesn't work, buy/rent your books from www.amazon.com or www.chegg.com . For some books amazon is better, and for...
