Assignment:Find the solution set of inequality 20000*(300/(300+0.775x)) >20000*(300/(300+x))*1.4 .
Question type: Inequality
Solution:
The inequality can be reduced to 1 inequality:
20000 * ( 300 / ( 300 + 0.775 * x ) ) >20000 * ( 300 / ( 300 + x ) ) * 1.4 (1)
From the definition field of divisor
300 + 0.775 * x ≠ 0 (2 )
From the definition field of divisor
300 + x ≠ 0 (3 )
From inequality(1):
x > -387.096774
From inequality(2):
x < -387.096774 或 x > -387.096774
From inequality(3):
x < -300 或 x > -300
From inequalities (1) and (2)
x > -387.096774 (4)
From inequalities (3) and (4)
-387.096774 < x < -300 或 x > -300 (5)
The final solution set is :
-387.096774 < x < -300 或 x > -300Your problem has not been solved here? Please take a look at the hot problems !
