Assignment:Find the solution set of inequality 1.571*(200*x-1630)+0.38465*(400+6*(28.73+10*x)*(x-6.1)/(x+5)) >3392.7272+3.927*x .
Question type: Inequality
Solution:
The inequality can be reduced to 1 inequality:
1.571 * ( 200 * x - 1630 ) + 0.38465 * ( 400 + 6 * ( 28.73 + 10 * x ) * ( x - 6.1 ) / ( x + 5 ) ) >3392.7272 + 3.927 * x (1)
From the definition field of divisor
x + 5 ≠ 0 (2 )
From inequality(1):
-5 < x < -4.928609 或 x > 17.896007
From inequality(2):
x < -5 或 x > -5
From inequalities (1) and (2)
-5 < x < -4.928609 或 x > 17.896007 (3)
The final solution set is :
-5 < x < -4.928609 或 x > 17.896007Your problem has not been solved here? Please take a look at the hot problems !
