Assignment:Find the solution set of inequality 0 ≤x∧x-5x ≤4 .
Question type: Inequality
Solution:
The inequality can be reduced to 2 inequalities:
0 ≤ x ^ x - 5 * x (1)
x ^ x - 5 * x ≤4 (2)
From inequality(1):
x ≤ 0.150412 或 x ≥ 2.650885
From inequality(2):
x ≤ 2.804243
From inequalities (1) and (2)
x ≤ 0.150412 或 2.650885 ≤ x ≤ 2.804243 (3)
The final solution set is :
x ≤ 0.150412 或 2.650885 ≤ x ≤ 2.804243Your problem has not been solved here? Please take a look at the hot problems !
