[ 1/1Inequality]
    Assignment:Find the solution set of inequality 0.5*sqrt(16-x)+0.5sqrt(4-x) >= 2 .
    Question type: Inequality
    Solution:
    The inequality can be reduced to 1 inequality：
        0.5 * sqrt ( 16 - x ) + 0.5 * sqrt ( 4 - x ) >= 2         (1)
        From the definition field of √
         16 - x ≥ 0        (2 )
        From the definition field of √
         4 - x ≥ 0        (3 )

---

    From inequality(1)：
         x ≤ 15/4
    From inequality(2)：
         x ≤ 16
    From inequality(3)：
         x ≤ 4

---

    From inequalities (1) and (2)
         x ≤ 15/4    (4)
    From inequalities (3) and (4)
         x ≤ 15/4    (5)

---

    The final solution set is :
         x ≤ 15/4
