2/3y - 3x = -6
Find x y equals 9? Solve for x: log base{5}(x+6)- log base{5}(x-5)=1? Could someone please help me find the LCD of this rational expression as well as the solution? 4/(x+1)+1/x=15/(2x)? Find the area of the region between the curves x=1−y2 and x=y2−1. I'm a little confused because of the x= not y= and still can't figure it!? How would I sketch f(x,y) = x^2 + 9y^2 on the xy plane? I know it is a circle.?
