[ 1/1Inequality]
Assignment:Find the solution set of inequality 10000/x+10000/(x+28.75) <149 .
Question type: Inequality
Solution:
The inequality can be reduced to 1 inequality:
10000 / x + 10000 / ( x + 28.75 ) <149 (1)
From the definition field of divisor
x ≠ 0 (2 )
From the definition field of divisor
x + 28.75 ≠ 0 (3 )
From inequality(1):
x < -28.75 或 -15.89721 < x < 0 或 x > 121.375398
From inequality(2):
x < 0 或 x > 0
From inequality(3):
x < -115/4 或 x > -115/4
From inequalities (1) and (2)
x < -28.75 或 -15.89721 < x < 0 或 x > 121.375398 (4)
From inequalities (3) and (4)
x < -115/4 或 -15.89721 < x < 0 或 x > 121.375398 (5)
The final solution set is :
x < -115/4 或 -15.89721 < x < 0 或 x > 121.375398Your problem has not been solved here? Please take a look at the hot problems !
