Exploring Adding and Subtracting Rational Expressions

The video tutorial explains compound inequalities, which are combinations of two or more inequalities joined by 'and' or 'or'. It covers two types: OR inequalities, which tend to graph outward, and AND inequalities, which graph inward. The tutorial provides examples, demonstrates how to graph these inequalities, and explains how to express solutions in interval notation. It also covers solving inequalities and consolidating them into single expressions.

What is a compound inequality?

• A single inequality with multiple solutions

• Two or more inequalities joined together with 'and' or 'or'

• An equation with multiple variables

• An inequality with only one variable

How do 'or' inequalities generally graph?

• Inward

• Outward

• Downward

• Upward
