-90>( with an line under that sign) 4T

I think you flip the sign or something? I'm not really sure..

Could someone please help?

**drwls**, Tuesday, January 4, 2011 at 2:48pmIf you divide or multiply both sides of an inequality by a positive number, you do not flip the direction of the sign.

In your case, divide both sides by 4 and you get

-22.5 > T

which can also be written

T < -22.5

(I left out the underline because I am too lazy to look up how to type it with ALT+ keys).

**drwls**, Tuesday, January 4, 2011 at 3:47pmOnly the parts of the line to the left of -22.5 are solutions. Maybe they want you to show a heavier line there; I don't know the recommended graphical rules in your case.
