Select one:

x≤−4

x≥4

x≤4

x≥−4

Answer 1

5x−9 ≥ 11

5x ≥ 11 + 9

5x ≥ 20

x ≥ 20/5

x ≥ 4

Done.

Answer 2

`x \geqslant 4`

Explanation:

1) Add 9 to both sides.

`5x \geqslant 11 + 9`

2) Simplify 11 + 9 to 20.

`5x \geqslant 20`

3) Divide both sides by 5.

`x \geqslant (20)/(5)`

4) Simplify 20/5 to 4.

`x \geqslant 4`

Thus, the answer is Option B.
