Exploring Adding and Subtracting Rational Expressions

This video tutorial covers the basics of inequality symbols, including less than, greater than, and equal to. It explains how to graph inequalities using open and closed circles on a number line. The tutorial also teaches how to translate verbal statements into inequalities and determine if a number is a solution. Finally, it covers solving inequalities, emphasizing the importance of flipping the inequality symbol when multiplying or dividing by a negative number.

What symbol represents a value that is less than or equal to another?

• <=

• >

• <

• >=

What does a closed circle on a graph indicate?

• The inequality is only 'greater than'

• The number is not included in the solution

• The number is included in the solution

• The graph represents an equation, not an inequality
