Solve the compound inequality. Graph your solutions on a number line. Show your work. 8 - x < 2 or 3x ≤ 9
+130511 8 - x < 2 U 3x ≤ 9
For the first add x to both sides and subtract 2 from both sides
6 < x or x > 6
For the second, divide both sides by 3
x ≤ 3
So, in interval notation, the answers are
( - infinity , 3 ] U (6 , infinity )
You should be able to do the number line part.......here's a resource to help with that : http://www.coolmath.com/algebra/07-solving-inequalities/03-interval-notation-01
