< > The arrow points the same way the inequality does IF THE VARIABLE IS ON THE LEFT-HAND SIDE . . . < > IF THE VARIABLE IS ON THE RIGHT-HAND SIDE. . . The arrow points the same way the inequality does You need to switch everything around! Mirror Image Everything! Whatever the inequality is pointing to, it needs to stay pointing to 3 > x = x < 3

x needs to be on the left to graph Graph the inequality. REMEMBER! 1. 3. 5. 2. 4. 6. x needs to be on the left to graph

PLUG IN the values to see if they make the inequality true Solution of an inequality: The solutions of the inequality x < 3 are : To identify solutions: Are the following solutions to the inequalities? 1. 2. 2 – 5x > 13 3. A A A B B B C C Write an inequality given a graph. 4. 5. 6. Any number that makes the inequality true All numbers that are less than 3 PLUG IN the values to see if they make the inequality true

a. b. d. e. Write the inequality in words. 4. 5. Define a variable and write an inequality for each situation. 9. Which is the inequality for the speed of snowmobiles? 6. A van can seat at most 10 passengers. a. b. 7. You must be at least 16 years old to obtain a driver’s license in Nevada. c. d. e. 8. You have to be at least 48 inches tall to ride the bumper cars.
