Help with this inequality question, please

It's from the Prep test:

Are x and y both positive?

The reason why I would very much like to mention the salary increase is because my official title hasn't changed over the last few years, but my responsibilities have. E...

Mention salary or not

Actually, my salary increase over the last few years is what is most impressive ( I think). I have avera...

Hi all, Here's the question: If x + y = a and x-y = b then 2xy = ? a) (a^2 - b^2) / 2 b) (b^2 - a^2) / 2 c) (a - b) / 2 d) ab / 2 e) (a^2 + b^2) / 2 Now...I was able to solve it, but it took some time because my first approach was wrong. My first approach was to isolate x and y. => x = a - y and y =...
