[ 1/1Inequality]
Assignment:Find the solution set of inequality 627*x/(1035641+x)*5-x*0.003 >0.04 .
Question type: Inequality
Solution:
The inequality can be reduced to 1 inequality:
627 * x / ( 1035641 + x ) * 5 - x * 0.003 >0.04 (1)
From the definition field of divisor
1035641 + x ≠ 0 (2 )
From inequality(1):
x > 1839.668196
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 > 1839.668196 (3)
The final solution set is :
x > 1839.668196Your problem has not been solved here? Please take a look at the hot problems !
