Final answer:
Robert's investment options are described by the inequalities x ≥ 2y (at least twice as much into government bonds as into municipal bonds) and y ≤ 5000 (no more than $5,000 into municipal bonds), which corresponds to option (a). x ≥ 2y and y ≤ 5000.
Step-by-step explanation:
The system of inequalities that describes Robert's investment options is represented by two conditions based on the information provided:
1. He wants to invest at least twice as much into government bonds than into municipal bonds.
2. He wants to invest no more than $5,000 into municipal bonds.
Letting x be the amount invested into government bonds, and y be the amount invested into municipal bonds, the system of inequalities can be written as:
- x ≥ 2y (at least twice as much into government bonds as into municipal bonds)
- y ≤ 5000 (no more than $5,000 into municipal bonds)
This corresponds to option (a): x ≥ 2y and y ≤ 5000.
