Final answer:
The inequality that represents the description is 8x + 9 ≥ 49 and the correct solution is x ≥ 5.
Step-by-step explanation:
To represent the given description, we have 8x + 9 ≥ 49. To solve this inequality, we can start by subtracting 9 from both sides: 8x ≥ 40. Next, we divide both sides by 8: x ≥ 5. Therefore, the correct option is a) x ≥ 5.
