Lesson 5.5 WarmUp:
Define a variable, write an inequality, and then solve it.
1) A number increased by 4 is at least 10.
2)
Three more than a number is less than twice
a number.
3)
The sum of twice a number and 5 is at most
3 less than a number.
Solve each inequality.

Lesson 5.5:
*Consider |x| < 3
x < 3 and x > ­3
So the graph would be:

And...
|x| > a
x > a or x < ­a
