**maths, variations checking!**

Your expression for y is incorrect, try this instead... A) y is inversely proportional to (x-1) if there exists a non-zero constant k such that y = k/(x-1). B) Given that when y=5 x=3, we can solve for k in y = k/(x-1) as follows: 5 = k/(3-1) 5 = k/2 5(2) = k [cross multiply] ...

Subtract the right side from both sides, leaving zero on the right side. [(x-1)/(x+2)] - [x/(x-2)] >= 0 Get common denominator. Multiply first term by (x-2)/(x-2). Multiply second term by (x+2)/(x+2). [(x-2)(x-1)]/[(x-2)(x+2)] - [(x+2)x]/[(x+2)(x-2)] >= 0 Multiply. (x^2...
