Which values of x satisfy the inequality 0 point 5 x minus 0 point 7 5 is greater than or equal to 3 point 2 5 ?

Add 0.75 to both sides: 0.5x ≥ 3.25 + 0.75 = 4. Divide both sides by 0.5, which is positive, so the inequality direction stays the same: x ≥ 8. The correct choice is x is greater than or equal to 8.
