[ 1/1Inequality]
Assignment:Find the solution set of inequality (2x-7+8)*(9.1*x+65.6)/(6.5+x)/100 >1.6 .
Question type: Inequality
Solution:
The inequality can be reduced to 1 inequality:
( 2 * x - 7 + 8 ) * ( 9.1 * x + 65.6 ) / ( 6.5 + x ) / 100 >1.6 (1)
From the definition field of divisor
6.5 + x ≠ 0 (2 )
From inequality(1):
-6.795778 < x < -6.5 或 x > 7.878195
From inequality(2):
x < -13/2 或 x > -13/2
From inequalities (1) and (2)
-6.795778 < x < -6.5 或 x > 7.878195 (3)
The final solution set is :
-6.795778 < x < -6.5 或 x > 7.878195Your problem has not been solved here? Please take a look at the hot problems !
