The Deep Dive
In the inequality \( v + 5 \geq 9 \), substituting \( v = 4 \) gives \( 4 + 5 = 9 \), which satisfies the requirement, thus \( v \geq 4 \) is a solution for option A. For option B, substituting \( v = 4 \) results in \( 4 + 5 > 9 \) leading to \( 9 > 9 \), which is false. In options C and D, \( v = 4 \) gives \( 9 \leq 8 \) and \( 9 < 8 \) respectively, both of which are false as well. So, the only answer is A.
