To fill in:The given compound inequality.
Answer to Problem 31E
Here, the compound inequality
Explanation of Solution
Given:
Calculation:
Given the inequalities:
Solve the inequality on the right:
The two inequalities have only one solution if there solutions are in the form:
Any other combination would lead to more than one solution. Since it is already known that the solution for the second inequality is
The solve the first inequality using the sign
Finally found the unknown sign of the first inequality (the other must not be checked because the inequality would have the complimentary solution
Conclusion:
Therefore, the compound inequality
