Answer B. y greater-than-or-equal-to StartFraction 8 over 15 EndFraction
Step-by-step explanation: To solve the compound inequality "Three-fifths + y ≥ 11/15", you can subtract 3/5 from both sides to get "y ≥ 2/15". Therefore, the correct answer is "y greater-than-or-equal-to StartFraction 2 over 15 EndFraction".
