To solve the inequality 2x - 8 ≥ 12, we first need to isolate the variable x on one side of the inequality. To do this, we add 8 to both sides, which gives us 2x ≥ 20. Then, we divide both sides by 2 to get x ≥ 10. This means that the solution to the inequality is any value of x that is greater than or equal to 10.
Looking at the given answer choices, we can see that the correct solution is OD. x-2 or x ≥ 10. The other answer choices do not match the solution we found, making them incorrect.
