Answer:
Step-by-step explanation:
We have to find an equation of the form 
, where a is the initial value, b is the rate, and x is the time.
Here, the initial amount if 72, so a = 72. We also know that the population triples every hour, which means b = 3. Plug these in:
The correct answer is option D.
Answer: 11
Step-by-step explanation: because I said so.
Answer:
x = 1.5
Step-by-step explanation:
We need a value of x that would result in 2x+9 = 12
2x+9 = 12
2x = 12 - 9
2x = 3
x = 3/2 or 1.5
====
CHECK
Does 2x+9 = 12 when x = 1.5?
2x+9 = 12
2(1.5)+9 = 12
3 + 9 = 12 YES
