Exercise 6 Page 609

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.

4v+18≥ 6v+10

SubIneq

LHS-6v≥RHS-6v

- 2v+18≥ 10

SubIneq

LHS-18≥RHS-18

- 2v ≥ - 8

DivNegIneq

Divide by - 2 and flip inequality sign

v≤ 4

This inequality tells us that all values less than or equal to 4 will satisfy the inequality. Therefore, our answer is F.
