Answers by Laura W.

For your first two equations, the vertical asymptotes come from the zeroes of the denominator, so just set the denominator equal to zero and solve.  Also, the vertical asymptotes tell you if there are any restrictions on the domain.  Here's an example: y = [x2 + 2x - 3] / [x2 -...

First off, we need the equations to really help you with this.  I can only give you a generic answer without them. I can tell you that for (a) to be correct, you will get an ordered pair (i.e. one value for x and one value for y). For (b) to be correct, you will get some useless-but-true...

stat question (answer)

Hi Mildred, It sounds like what you are doing in this question is a two-tailed hypothesis test.  Also, from what you've given, it seems like you don't have the standard deviation for the whole university (population SD).  Therefore, you would normally want a two-tailed t-test, however,...

I would think of this problem as a big right triangle.  Draw a triangle like this on your paper:  /| The slanted line should be labeled 10,300 feet at the bottom and 12,300 feet at the top.  Think of this slanted line as how the skiers went down the mountain. The line that's...

Should that be + 5a at the end? or are you missing some +s and -s between the 14 and 3 and between the xyz and 5?   Step 1:  Use the distributive property on (30x -7)yz Step 2:  Combine like terms (eg. all constants, all ___xyz's)

What kind of equations have you learned about?  Linear, polynomial, exponential?  If you give more details, I could help you with a specific type of equation.   What about interest rate and growth on a savings account?  That would be an exponential equation based on time...
