Unformatted text preview: 1 Math 1300 Section 1.7 Solving Linear Inequalities An inequality is a mathematical sentence, except instead of an equal sign = you find one of the following signs: < > The symbols > and < are called strict inequalities, and and are inequalities that include equals (read these last two signs as greater than or equal to and less than or equal to, respectively). A linear equation (Section 1.6) has one, none, or many solutions. A linear inequality has a solution that is an interval of the real number line and the answers can be written in what is called interval notation . This ensures that you have the complete answer. In this section, we will only be concerned with real number solutions. 2 Math 1300 Section 1.7 Interval Notation: Inequality Interval Notation x A < ( 29 , A- The rounded bracket means that A is not included x A ( ] , A- The square bracket means that A is included x B ( 29 , B x B [ 29 , B A x B < < ( 29 , A B A x B [ ] , A B 3...
