Assignment:Find the solution set of inequality (2*(1.6+x)+0.8*9)*(72.69+7.8*x)/(11.6+x)/90 >1.5 .
Question type: Inequality
Solution:
The inequality can be reduced to 1 inequality:
( 2 * ( 1.6 + x ) + 0.8 * 9 ) * ( 72.69 + 7.8 * x ) / ( 11.6 + x ) / 90 >1.5 (1)
From the definition field of divisor
11.6 + x ≠ 0 (2 )
From inequality(1):
-11.6 < x < -10.712493 或 x > 4.847108
From inequality(2):
x < -58/5 或 x > -58/5
From inequalities (1) and (2)
-11.6 < x < -10.712493 或 x > 4.847108 (3)
The final solution set is :
-11.6 < x < -10.712493 或 x > 4.847108Your problem has not been solved here? Please take a look at the hot problems !
