Question 85864: Help! I am stuck on solving a radical equation.
The original problem is this: sq.rt.2y+7 plus 4 = y.
I know I have to isolate the radical to one side, then square both sides of the equation. Getting that far, I have: (sq.rt.2y+7)= (y-4).
After that I am completely stuck! Please help!
Thank you!

Question 85981: Can someone please graph this curve for me, here is my work so far:
For the function y= 1/x-2
Give the y values for x = -1, 0, 1, 2, 3, 4.
Answer: y = -1/3
y = -1/2
y= -1
y= 1/0
y= 1
y= 1/2
Show work in this space.
y= 1/-1-2
y= 1/0-2
y= 1/1-2
y= 1 /2-2
y= 1/3-2
y= 1 /4-2
Using these points, draw a curve.
Show graph here.
