☆2 inequalities
[ 1/2Inequality]
Assignment:Find the solution set of inequality 2x-3(x-1) <2 .
Question type: Inequality
Solution:
The inequality can be reduced to 1 inequality:
2 * x - 3 * ( x - 1 ) <2 (1)
From inequality(1):
x > 1
The final solution set is :
x > 1[ 2/2Inequality]
Assignment:Find the solution set of inequality 2/x+5 >= x .
Question type: Inequality
Solution:
The inequality can be reduced to 1 inequality:
2 / x + 5 >= x (1)
From the definition field of divisor
x ≠ 0 (2 )
From inequality(1):
x ≤ -0.372281 或 0 ≤ x ≤ 5.372281
From inequality(2):
x < 0 或 x > 0
From inequalities (1) and (2)
x ≤ -0.372281 或 0 < x ≤ 5.372281 (3)
The final solution set is :
x ≤ -0.372281 或 0 < x ≤ 5.372281 Your problem has not been solved here? Please take a look at the hot problems !
