LT#3ab: I can solve compound inequalities.
I can graph compound inequalities on a number line.
Compound inequality =
What does 'and' mean?
What does 'or' mean?
A compound inequality consists of two separate inequalities joined by and or or.
A number is a solution to both of the inequalities.
A number is a solution to only one of the inequalities.
