Question

Solve the inequality.

-2x - 1 ≥ 9

Question 4 options:

x ≤ -5


x ≥ -5


x ≥ 5

Answer 1

x ≤ -5

Explanation:

-2x - 1 ≥ 9

-2x ≥ 10

Divide both sides by -2

(Flip/reverse the inequality when you multiply/divide by a negative value)

x ≤ 10/-2

x ≤ -5

Answer 2

x ≤ - 5

Explanation:

Given

- 2x - 1 ≥ 9 ( add 1 to both sides )

- 2x ≥ 10

Divide both sides by - 2, reversing the symbol as a result of dividing by a negative quantity.

x ≤ - 5
