What is the vertical asymptotic line of Y=(x^3-3x^2)/(9-x^2). thank you

inequality
Factor out (x-3). Y=(x^3-3x^2)/(9-x^2) = x^2(x-3)/[(3-x)(x+3)] = -x^2/(x+3) This is asymptotic to a vertical line at x=-3

This has nothing to do with inequalities. You are simply looking asymptotes. First of all, what is an asymptote? You need to know the definition of math terms. An asymptote is a boundary line that a graph gets very, very, very close to but NEVER (say NEVER) actually touches. ...

Janice and Leonard together would like to save more than $3,500. They have saved $425 saved so far. Janice can save $120 more than twice what Leonard can save each month. How much money will they each need to save to reach their goal?
Thursday, March 17, 2011 at 12:21am by lisa

inequality
If you take the amount they need, $3,500 and subtract $425 which they already have, then subtract $120 that Janice will save more than Leonard, divide it, getting $1477.50 is what each needs to save. To check that take the $1477.50 X 2, plus 120 and 425 = $3.500 Sra
