Exercise 10 Page 361

What can you do to isolate a variable in an inequality?

f ≥ - 2

Practice makes perfect
Inequalities can be solved in the same way as equations — by performing inverse operations on both sides until the variable is isolated. The only difference is that when you divide or multiply by a negative number, you must reverse the inequality sign.
-(7f+18) -2f ≤ 0
- 7f-18-2f ≤ 0
- 9f-18≤ 0
- 9f≤ 18
f ≥ - 2
This inequality tells us that all values greater than or equal to - 2 will satisfy the inequality.
