Assignment:Find the solution set of inequality 3625.12-562.07×x ≤(105.75+9.3×x)/(14.1+x)×(15.6+x) .
Question type: Inequality
Solution:
The inequality can be reduced to 1 inequality:
3625.12 - 562.07 × x ≤ ( 105.75 + 9.3 × x ) / ( 14.1 + x ) × ( 15.6 + x ) (1)
From the definition field of divisor
14.1 + x ≠ 0 (2 )
From inequality(1):
x ≥ 6.138406
From inequality(2):
x < -141/10 或 x > -141/10
From inequalities (1) and (2)
x ≥ 6.138406 (3)
The final solution set is :
x ≥ 6.138406Your problem has not been solved here? Please take a look at the hot problems !
