    Assignment:Find the solution set of inequality -10x^2+800x ≥8000 .
    Question type: Inequality
    Solution:
    The inequality can be reduced to 1 inequality：
        -10 * x ^ 2 + 800 * x ≥8000         (1)

---

    From inequality(1)：
         11.715729 ≤ x ≤ 68.284271

---

    The final solution set is :
         11.715729 ≤ x ≤ 68.284271
