**Eric**, Sunday, March 24, 2013 at 4:07pmI got the answer x >_ -81, is that correct?

**Reiny**, Sunday, March 24, 2013 at 4:21pmlooking at all those positive numbers on the left, there is no way the inequality sign could have changed.

I am assuming your _ < is ≤ ??

.1(.1x + .1) < -.8

times 10

.1x + .1 ≤ -8

times 10 again

x + 1 < -80

x≤ -81 - College Algerbra -
**Eric**, Sunday, March 24, 2013 at 4:36pmThanks Reiny, you assumed correct, how did you get the line under the greater than sign? You are a very smart and kind woman to have been such a great help, Thanks!

**Reiny**, Sunday, March 24, 2013 at 4:42pmI answer most of the questions on a Mac, where I hold down the "option" key as I press the <

There are combinations of key like that on the PC also, I don't have the list handy right now.

BTW, I am an old retired guy, not a woman. - College Algerbra -
**Eric**, Sunday, March 24, 2013 at 4:54pmSorry Mr. Reiny, I guess I should of figured that out since you are so smart at doing the math problems. I do not have an option key on my windows 7 keyboard but I bet there is another way I can do the underline thing. Thanks Again for taking time out of your day to help us Mathematically Challenged students, God Bless You!
