[ 1/1Inequality]
Assignment:Find the solution set of inequality (8+x)/(17+x) >0.56 .
Question type: Inequality
Solution:
The inequality can be reduced to 1 inequality:
( 8 + x ) / ( 17 + x ) >0.56 (1)
From the definition field of divisor
17 + x ≠ 0 (2 )
From inequality(1):
x < -17 或 x > 38/11
From inequality(2):
x < -17 或 x > -17
From inequalities (1) and (2)
x < -17 或 x > 38/11 (3)
The final solution set is :
x < -17 或 x > 38/11Your problem has not been solved here? Please take a look at the hot problems !
