the problem is 92 is greater than or equal to negative 4p.

why is the answer p is greater than or equal to negative 23?

I am confused! why is it not p is less than or equal to negative 23?

**Damon**, Thursday, April 17, 2008 at 9:00pm92 >/= -4 p

divide both sides by -4

Rule:

When you multiply or divide both sides of an inequality by a NEGATIVE quantity, you CHANGE the DIRECTION of the arrow

So:

-23 </= p

Thanks for the help. Let me see if I get it now. So,

-2x < -4

divide both sides by -2

answer is x > 2

I had x < 2, but I reverse the sign since I divided by a -2 on both sides, correct?
