[ 1/1Inequality]
Assignment:Find the solution set of inequality 10000/(x+0)+10000/(x+4.8) <= 150 .
Question type: Inequality
Solution:
The inequality can be reduced to 1 inequality:
10000 / ( x + 0 ) + 10000 / ( x + 4.8 ) <= 150 (1)
From the definition field of divisor
x + 0 ≠ 0 (2 )
From the definition field of divisor
x + 4.8 ≠ 0 (3 )
From inequality(1):
x ≤ -4.8 或 -2.443186 ≤ x ≤ 0 或 x ≥ 130.976519
From inequality(2):
x < 0 或 x > 0
From inequality(3):
x < -24/5 或 x > -24/5
From inequalities (1) and (2)
x ≤ -4.8 或 -2.443186 ≤ x < 0 或 x ≥ 130.976519 (4)
From inequalities (3) and (4)
x < -24/5 或 -2.443186 ≤ x < 0 或 x ≥ 130.976519 (5)
The final solution set is :
x < -24/5 或 -2.443186 ≤ x < 0 或 x ≥ 130.976519Your problem has not been solved here? Please take a look at the hot problems !
