Assignment:Find the solution set of inequality (0.5x+1)-(2.25x/(2.5-0.25x)) >0 .
Question type: Inequality
Solution:
The inequality can be reduced to 1 inequality:
( 0.5 * x + 1 ) - ( 2.25 * x / ( 2.5 - 0.25 * x ) ) >0 (1)
From the definition field of divisor
2.5 - 0.25 * x ≠ 0 (2 )
From inequality(1):
-11.708204 < x < 1.708204 或 x > 10
From inequality(2):
x < 10 或 x > 10
From inequalities (1) and (2)
-11.708204 < x < 1.708204 或 x > 10 (3)
The final solution set is :
-11.708204 < x < 1.708204 或 x > 10Your problem has not been solved here? Please take a look at the hot problems !
