3. Review y > -6 y > 4 y ≤ -9 1. -2y – 5 < 7 2. 3y – 5 > 7
Write the linear inequality for all real numbers greater than or equal to 4.
Write the verbal phrase that describes x ≤ -2.
Is the number 4.78 a solution of x < 5? Is the number 6 a solution of x < 6?
Solve the inequality 5 – 2x ≥ 3. Then graph it.
1. -2y – 5 < 7
y > -6
2. 3y – 5 > 7

7. With Fractions

8. Variables on both sides
-3f - 7 ≥ -f + 9
Add f on both sides
+f f
-2f - 7 ≥
Add 7 on both sides
-2f ≥
divide -2 on both sides
f ≤ -8
