1. The problem is to determine which values of $b$ satisfy the inequality $1 < b$. 2. The inequality $1 < b$ means that $b$ must be greater than 1. 3. We check each given value of $b$: - For $b = 9$, since $9 > 1$, it satisfies the inequality. - For $b = 5$, since $5 > 1$, it satisfies the inequality. - For $b = 2$, since $2 > 1$, it satisfies the inequality. - For $b = 11$, since $11 > 1$, it satisfies the inequality. 4. Therefore, all given values $b = 9, 5, 2, 11$ satisfy the inequality $1 < b$. Final answer: $b = 9, 5, 2, 11$ all satisfy $1 < b$.
