[ 1/1Inequality]
Assignment:Find the solution set of inequality 1/(8*(1-x)) ≥1/4+x/9(1-x) .
Question type: Inequality
Solution:
The inequality can be reduced to 1 inequality:
1 / ( 8 * ( 1 - x ) ) ≥1 / 4 + x / 9 * ( 1 - x ) (1)
From the definition field of divisor
8 * ( 1 - x ) ≠ 0 (2 )
From inequality(1):
x ≤ -0.878851 或 0.549557 ≤ x ≤ 1 或 x ≥ 2.329293
From inequality(2):
x < 1 或 x > 1
From inequalities (1) and (2)
x ≤ -0.878851 或 0.549557 ≤ x < 1 或 x ≥ 2.329293 (3)
The final solution set is :
x ≤ -0.878851 或 0.549557 ≤ x < 1 或 x ≥ 2.329293Your problem has not been solved here? Please take a look at the hot problems !
