If -1 < 2y < 0, what are the possible values of |y| - y ?
(|y| is the absolute value of y)
I know the interval is 0 < y < 1 but I don't how to show it algebraically..
I thought the same too, but the solution of 0 < x < 1 came from collegeboard (it's a sample sat problem) How could they mislead us with the answer provided?

That solution is correct. Look at my reply. ADD and we get
How did you get those two intervals plato? Where did the -y come from as well? and why is the 0.5 on the right hand side? I get it to look like -0.5 < y < 0 when I worked out the algebra
