Determine whether the statement is true, false, or sometimes true. Explain or show why.
If x is positive and y = -x, then xy is negative.

Is this always true or sometimes true?

False. If x is positive and you put a negative in front of it, you have to divide by negative one which would then give you positive x again. If you multiply a positive x and a positive y then xy is positive. False. Hope that helps.!!!:)

If y = -x, the xy = x(-x).

What do you get when you multiply a positive by a negative?
