Question 159154: Hello:
I'm taking a college Intermediate Algebra Class and have not even thought about Algebra for about 4 years. My instructor has this online question that I do not understand with several multiple choice anwswers. None of which match the several attempts I have made.
Here's the question: "Multiply by definition exponents as needed"
x^2-6xy-y^2-4x^2y^3
|Note: there are no perenthese or operations other than the negative signs.|
The answers vary but have a general theme:
a) 24x^3y^4x^2y^5 (in despiration I chose this one as a guess, it's wrong)
b) 24x^3y^4x^2y^5 (Yeah I know it's the same)
c) 25x^3y^4x^2y^5
d) 26x^3y^4x^2y^5
I've tried everthing I can think of to do this problem. I just do not understand how to come up with one of these answers!
Could you please show me HOW to do this problem? And explaine each step? thanks very much.

Question 159065: Suppose that the number of new homes built, H, in a city over a period of time, t, is graphed on a rectangular coordinate system where time is on the horizontal axis. Suppose that the number of homes built can be modeled by an exponential function, H= p * at , where p is the number of new homes built in the first year recorded. If you were a homebuilder looking for work, would you prefer that the value of a to be between 0 and 1 or larger than 1? Explain your reasoning.

Question 161452This question is from textbook Beginning Algebra

: Hi, I'm having a real difficult time understanding why the answer to the following problem is like it is.

x^3y^2/5xy6
My text book shows the answer as x^2/5y^4
Why does x go in the numerator, and y in the denominator?
My text book fails to explain why this is.
When subtracting the y exponents, the larger number is the denominator, and the smaller number is in the numerator, so shouldn't the end result look like this:
1/5x^2y^4

I can't get past this. I'd really appreciate any help.This question is from textbook Beginning Algebra
