[ 1/1Inequality]
Assignment:Find the solution set of inequality (2*x-4.8+0.8*9.5)*(9.1*x+67.2)/100/(7.6+x) >1.6 .
Question type: Inequality
Solution:
The inequality can be reduced to 1 inequality:
( 2 * x - 4.8 + 0.8 * 9.5 ) * ( 9.1 * x + 67.2 ) / 100 / ( 7.6 + x ) >1.6 (1)
From the definition field of divisor
7.6 + x ≠ 0 (2 )
From inequality(1):
-7.6 < x < -7.511671 或 x > 7.518264
From inequality(2):
x < -38/5 或 x > -38/5
From inequalities (1) and (2)
-7.6 < x < -7.511671 或 x > 7.518264 (3)
The final solution set is :
-7.6 < x < -7.511671 或 x > 7.518264Your problem has not been solved here? Please take a look at the hot problems !
