Assignment:Find the solution set of inequality 2371.76+213×x+2.27×(240.8+2.8(105.75+9.3x)×(12.6+x)/(14.1+x)) ≥6682.23+12.9x .
Question type: Inequality
Solution:
The inequality can be reduced to 1 inequality:
2371.76 + 213 × x + 2.27 × ( 240.8 + 2.8 * ( 105.75 + 9.3 * x ) × ( 12.6 + x ) / ( 14.1 + x ) ) ≥6682.23 + 12.9 * x (1)
From the definition field of divisor
14.1 + x ≠ 0 (2 )
From inequality(1):
x ≥ 12.233999
From inequality(2):
x < -141/10 或 x > -141/10
From inequalities (1) and (2)
x ≥ 12.233999 (3)
The final solution set is :
x ≥ 12.233999Your problem has not been solved here? Please take a look at the hot problems !
