b. $d < 3$
c. $d \leq 3$
d. $d \geq 3$

a professional meeting is scheduled to start no earlier than 9:00 am. which inequality best represents the start time $t$, where $t$ is in hours?
a. $t < 9$
b. $t \leq 9$
c. $t > 9$
d. $t \geq 9$

Explanation:

Step1: Analyze first problem

Let $d$ = water depth. "Not exceed 3" means $d$ ≤ 3. So option c.

Step2: Analyze second problem

Let $t$ = start time. "No earlier than 9" means $t$ ≥ 9. So option d.

Answer:

c. $d \leq 3$, d. $t \geq 9$
