    Assignment:Find the solution set of inequality (-457*x+(1-x)*40911)/(sqrt(0.0232*x^2+7.783*x^2)) ≤0 .
    Question type: Inequality
    Solution:
    The inequality can be reduced to 1 inequality：
         ( -457 * x + ( 1 - x ) * 40911 ) / ( sqrt ( 0.0232 * x ^ 2 + 7.783 * x ^ 2 ) ) ≤0         (1)
        From the definition field of √
         0.0232 * x ^ 2 + 7.783 * x ^ 2 ≥ 0        (2 )
        From the definition field of divisor
         sqrt ( 0.0232 * x ^ 2 + 7.783 * x ^ 2 ) ≠ 0        (3 )

---

    From inequality(1)：
         x ≥ 0.988953
    From inequality(2)：
         x ≤ 0 或  0 ≤ x ≤ 0 或  x ≥ 0
    From inequality(3)：
         x < 0 或  x ＞ 0

---

    From inequalities (1) and (2)
         x ≥ 0.988953    (4)
    From inequalities (3) and (4)
         x ≥ 0.988953    (5)

---

    The final solution set is :
         x ≥ 0.988953
