☆4 inequalities
[ 1/4Inequality]
Assignment:Find the solution set of inequality 230000/240/x <500 .
Question type: Inequality
Solution:
The inequality can be reduced to 1 inequality:
230000 / 240 / x <500 (1)
From the definition field of divisor
x ≠ 0 (2 )
From inequality(1):
x < 0 或 x > 1.916667
From inequality(2):
x < 0 或 x > 0
From inequalities (1) and (2)
x < 0 或 x > 1.916667 (3)
The final solution set is :
x < 0 或 x > 1.916667[ 2/4Inequality]
Assignment:Find the solution set of inequality 230000/400/x <500 .
Question type: Inequality
Solution:
The inequality can be reduced to 1 inequality:
230000 / 400 / x <500 (1)
From the definition field of divisor
x ≠ 0 (2 )
From inequality(1):
x < 0 或 x > 23/20
From inequality(2):
x < 0 或 x > 0
From inequalities (1) and (2)
x < 0 或 x > 23/20 (3)
The final solution set is :
x < 0 或 x > 23/20[ 3/4Inequality]
Assignment:Find the solution set of inequality 230000/[400*(1+25%)]/x <500 .
Question type: Inequality
Solution:
The inequality can be reduced to 1 inequality:
230000 / ( 400 * ( 1 + 25 % ) ) / x <500 (1)
From the definition field of divisor
x ≠ 0 (2 )
From inequality(1):
x < 0 或 x > 23/25
From inequality(2):
x < 0 或 x > 0
From inequalities (1) and (2)
x < 0 或 x > 23/25 (3)
The final solution set is :
x < 0 或 x > 23/25[ 4/4Inequality]
