Assignment:Find the solution set of inequality 1.6/((10-x)*1.6+55) <0.5/(16+0.5*x) .
Question type: Inequality
Solution:
The inequality can be reduced to 1 inequality:
1.6 / ( ( 10 - x ) * 1.6 + 55 ) <0.5 / ( 16 + 0.5 * x ) (1)
From the definition field of divisor
( 10 - x ) * 1.6 + 55 ≠ 0 (2 )
From the definition field of divisor
16 + 0.5 * x ≠ 0 (3 )
From inequality(1):
-32 < x < 99/16 或 x > 44.375
From inequality(2):
x < 355/8 或 x > 355/8
From inequality(3):
x < -32 或 x > -32
From inequalities (1) and (2)
-32 < x < 99/16 或 x > 44.375 (4)
From inequalities (3) and (4)
-32 < x < 99/16 或 x > 44.375 (5)
The final solution set is :
-32 < x < 99/16 或 x > 44.375Your problem has not been solved here? Please take a look at the hot problems !
