1-7 Absolute Value Equations and Inequalities – We learned to solve equations and inequalities that involve absolute value. Then we used equations and inequalities that involve absolute value to solve problems. We learned that the solution to an absolute value equation either has two solutions, one positive and one negative, or there is no value of x that makes the absolute value equation true. We discovered that the solution to an absolute value inequality is a compound inequality that uses or or and. Then we reviewed for a test on Solving Equations and Inequalities.
