To determine which of the given values is a solution to the inequality \( v \leq 5 \), we check each value:
- For \( v = 1 \): \( 1 \leq 5 \) (True)
- For \( v = 7 \): \( 7 \leq 5 \) (False)
- For \( v = 8 \): \( 8 \leq 5 \) (False)
- For \( v = 9 \): \( 9 \leq 5 \) (False)
The only value that satisfies the inequality is \( v = 1 \).
