Assignment:Find the solution set of inequality (2*x+7.2+0.8*9.5)*(7.2*x+120.98)/100/(13.6+x) >1.6 .
Question type: Inequality
Solution:
The inequality can be reduced to 1 inequality:
( 2 * x + 7.2 + 0.8 * 9.5 ) * ( 7.2 * x + 120.98 ) / 100 / ( 13.6 + x ) >1.6 (1)
From the definition field of divisor
13.6 + x ≠ 0 (2 )
From inequality(1):
-14.889603 < x < -13.6 或 x > 1.797936
From inequality(2):
x < -68/5 或 x > -68/5
From inequalities (1) and (2)
-14.889603 < x < -13.6 或 x > 1.797936 (3)
The final solution set is :
-14.889603 < x < -13.6 或 x > 1.797936Your problem has not been solved here? Please take a look at the hot problems !
