One Step Inequalities Review

Adding Negative Numbers: Same signs add and keep the sign Different signs subtract and keep the sign of the larger Subtracting Negative Numbers Same Change Flip Multiplying and Dividing Negative Numbers Same signs = Positive Different Signs = Negative

One Step Inequalities Review The “pac-man” always opens up to the bigger number! < (less than) > (greater than) < (less than or equal to) > (greater than or equal to)

One Step Inequalities Review Graphing When do you use an open circle? When do you use a closed circle? Flipping the sign You flip the sign when you MULTIPLY OR DIVIDE NEGATIVE NUMBERS!!!!!!!!!!!

One Step Inequalities Review Shading your line graph When the variable is less than the number shade LEFT Example: x x When the variable is greater then the number shade RIGHT Example: x > 5 or -4 < x

One Step Inequalities Review Example: -2x > 12

One Step Inequalities Review Example: -17 < n – 9

One Step Inequalities Review Example: 28 > -7y
