Assignment:Find the solution set of inequality 2(25x-150/x+50) ≥1500 .
Question type: Inequality
Solution:
The inequality can be reduced to 1 inequality:
2 * ( 25 * x - 150 / x + 50 ) ≥1500 (1)
From the definition field of divisor
x ≠ 0 (2 )
From inequality(1):
-0.21267 ≤ x ≤ 0 或 x ≥ 28.21267
From inequality(2):
x < 0 或 x > 0
From inequalities (1) and (2)
-0.21267 ≤ x < 0 或 x ≥ 28.21267 (3)
The final solution set is :
-0.21267 ≤ x < 0 或 x ≥ 28.21267Your problem has not been solved here? Please take a look at the hot problems !
