☆4 inequalities
[ 1/4Inequality]
Assignment:Find the solution set of inequality x2+x3+x4 >= 4 .
Question type: Inequality
Solution:
The inequality can be reduced to 1 inequality:
x * 2 + x * 3 + x * 4 >= 4 (1)
From inequality(1):
x ≥ 4/9
The final solution set is :
x ≥ 4/9[ 2/4Inequality]
Assignment:Find the solution set of inequality x1+x2+x3+x4+x5 <= 10 .
Question type: Inequality
Solution:
The inequality can be reduced to 1 inequality:
x * 1 + x * 2 + x * 3 + x * 4 + x * 5 <= 10 (1)
From inequality(1):
x ≤ 2/3
The final solution set is :
x ≤ 2/3[ 3/4Inequality]
Assignment:Find the solution set of inequality 6*x1+6*x2-4*x3-4*x4+36*x5 <= 0 .
Question type: Inequality
Solution:
The inequality can be reduced to 1 inequality:
6 * x * 1 + 6 * x * 2 - 4 * x * 3 - 4 * x * 4 + 36 * x * 5 <= 0 (1)
From inequality(1):
x ≤ 0
The final solution set is :
x ≤ 0[ 4/4Inequality]
Assignment:Find the solution set of inequality 4*x1+10*x2-x3-2*x4-3*x5 <= 0 .
Question type: Inequality
Solution:
The inequality can be reduced to 1 inequality:
4 * x * 1 + 10 * x * 2 - x * 3 - 2 * x * 4 - 3 * x * 5 <= 0 (1)
From inequality(1):
x ≥ 0
The final solution set is :
