Solving One-Variable Inequalities

The video tutorial covers solving inequalities in one variable. It begins with an introduction to inequality symbols and their meanings, followed by instructions on how to graph inequalities using open and filled circles. The tutorial then demonstrates solving inequalities through examples, including both simple and multi-step problems. Key concepts such as flipping inequality signs when multiplying or dividing by negative numbers are highlighted. The video concludes with a summary of the steps involved in solving and graphing inequalities.

What symbol is used to represent a value that is not included in the inequality range?
