[ 1/1Inequality]
Assignment:Find the solution set of inequality 575*x/(950000+x)*5-x*0.003 >0.05 .
Question type: Inequality
Solution:
The inequality can be reduced to 1 inequality:
575 * x / ( 950000 + x ) * 5 - x * 0.003 >0.05 (1)
From the definition field of divisor
950000 + x ≠ 0 (2 )
From inequality(1):
x > 2950.689852
From inequality(2):
x ∈ R (R为全体实数),即在实数范围内,不等式恒成立!
From inequalities (1) and (2)
x > 2950.689852 (3)
The final solution set is :
x > 2950.689852Your problem has not been solved here? Please take a look at the hot problems !
