13.5 Inequalities (p.300-303)

I. An inequality is an algebraic sentence that contains the symbol <, >, ≤, ≥, or ≠ because the sides are not equal
II. An inequality can sometimes be solved the same way as an equation
III. When graphing on a number line
A. <> Use an open circle if the value at that spot is not included in the solution
B. ≤ or ≥ Use a filled in circle if the value at that spot is a possible solution
IV. If you multiply both sides of an inequality by a negative number it will reverse the direction of the inequality sign
