Final answer:
The inequality for 'x is at least 17' is x ≥ 17. Values that satisfy the inequality are 17, 18, 19, and 20.
Step-by-step explanation:
To write the inequality for the phrase 'x is at least 17,' we use the greater than or equal to symbol (≥). The inequality would be x ≥ 17. This means that any value of x that is greater than or equal to 17 satisfies the inequality. In this case, the values that satisfy the inequality would be 17, 18, 19, and 20.
