[ 1/1Inequality]
Assignment:Find the solution set of inequality 10000/x+10000/(x+115*0.3) <150 .
Question type: Inequality
Solution:
The inequality can be reduced to 1 inequality:
10000 / x + 10000 / ( x + 115 * 0.3 ) <150 (1)
From the definition field of divisor
x ≠ 0 (2 )
From the definition field of divisor
x + 115 * 0.3 ≠ 0 (3 )
From inequality(1):
x < -34.5 或 -19.445565 < x < 0 或 x > 118.278898
From inequality(2):
x < 0 或 x > 0
From inequality(3):
x < -69/2 或 x > -69/2
From inequalities (1) and (2)
x < -34.5 或 -19.445565 < x < 0 或 x > 118.278898 (4)
From inequalities (3) and (4)
x < -69/2 或 -19.445565 < x < 0 或 x > 118.278898 (5)
The final solution set is :
x < -69/2 或 -19.445565 < x < 0 或 x > 118.278898Your problem has not been solved here? Please take a look at the hot problems !
