Problem: x/4 - 4/x = 0 Directions:Solve the rational expression. x = -4 x = 4

Solve and graph(using words)the inequalities.Then describe the graphs using words. Example:x>5andx<9.[There would be an open circle on the 5 and an open circle on the 9.The shading is between the 2numbers. My Problem: -6<x+3<6(Remember,this is an "and" st...

*Describe your graphs using words. 2x > -6 and x - 4 < 3 You have to solve for x. x>= -3 and x<=7 Doesnt the line segment start at -3 and end at x=7?

Problem: (y+2)/(y) = 1/(y-5) Directions: Solve the rational expression. Remember that if: a/b = c/d then: a * d = b * c I believe in school they call this the fraction crossover rule or fraction cross rule or something like that. i would work it like a proportion and cross mul...

Running Journal: Macbeth (Act 1 Scene 1) Thunder and lightning; enter three Witches: In the play as a whole, people are tossed about by forces that they cannot control, and so it is in the opening scene. The witches, blown by the storms of nature and war, swirl in, then out. A...

Problem: (2x+1)/(x^2-16) - (x^2-6x-7)/x^2-11x+28 What I Got: -x^2-3x-3/x^2-16 correct RIGHTAMUNDO WLCM :)

Problem: (x+2)/2x^2+5x+2 + (x-3)/2x^2-5x-3 What I Got: 0 at x=0, one gets 2/2 + -3/-3 which is not zero. You messed up a sign, I suspect. you are right girl

Problem: 4x/(x+2)-8/(x-1) What I Got: 4x^2-4x-16/(x+2)(x+1) *I had to simplify the rational expression No. At x=0, it doesn't check. The starting problem gives 8, your answer gives -8. I suspect a sign error somewhere. Probably in the denominator, the x+1 should be x-1

x^2/x+3 - 5/x+3=0 *Please solve the rational equation Your non use of parenthesis is annoying and most confusing. I assume you meant x^2/(x+3) - 5/(x+3)=0 multiply both sides of the equation by x+3, and solve.

y+2/y =1/y-5 *Please solve the rational equation I am not certain if the right term is 1/(y-5) or the right side is 1/y -5
