Algebra-1

The symbol "≥" means "greater than or equal to", so the correct way to say the inequality " x ≥ 15”is: D. x is greater than or equal to 15.

The other options are incorrect:

Option A: x is less than or equal to 15: this would be written as x ≤ 15. It includes values of x that are either less than or exactly equal to 15. This is not equivalent to x ≥ 15.
