over means divided by
For all x>0 and y>0, the radical expression squareroot of x over squareroot of 3 - squareroot of y. The answer is equivalent to 3x + squareroot of xy over 9x-y
I do not know how they arrived at the answer.
x square + 12* + 32 divided by x+4 for all x < -3
the answer is -x -3. how did they get that.
Point A (-4, 1) is the standard (x,y) coordinate plane. what must be the coordinates of point B so that the x=2 is the perpendicular bisector of AB?
please kindly show all your workings. Thanks a lot.
