What does this mean in words please? Thanks!

I need the horizontal asymptote for f(x) = (x)/(x^2 -4) Can someone please show me. I already figured out that The y-intercept is 0. The vertical asymptotes are x = -2, x = 2 So now all i need is horizontal asymptote for f(x) = (x)/(x^2 -4)

My mistake 4-(9) = -5 ? This is what I believe to be the correct answer

Algebra
Please Solve: 4-x=-5 I thought the answer was -9 but that doesn't seem to be it. Can someone please help? Thanks! This is what I have: 6. 4-x=-5 The problem to solve is: 4-x=-5 Subtract 4 from both sides x = -9 Then divie by -1 Would the answer be 9? To Check: 4- - 9 = -5

In this problem: -2/a+2 + 3a/2a-1 First I made the denominators alike: -2(2a-1)/(a+2)(2a-1) + 3a(a+2)/(a+2)(2a-1) = -4a+2/(a+2)(2a+1) + 3a^2+6a/(a+2)(2a-1) What I want to know is if I can eliminate the a+2 for the first fraction, on both the numerator and the denominator?
