Solving Inequalities

s - 10 ≤ 1

• s ≤ 11
• s ≤ 9
• s ≥ 11
• s ≥ 9

• X < 10

• 10 < X

• X = 10

Answer explanation

10 ≥ x - 3

• x ≤ 13

• x ≥ 13

• x ≤ 7

• x ≥ 7

Answer explanation

REMEMBER! When you see an inequality with the variable on the right hand side, flip the entire thing to put the variable on the left:

7 < X becomes X > 7

Graph the inequality X < -17

Answer explanation

Did your graph use an open circle? Did your arrow point to the left? If so, great job!!
