Hello,
y=-3x+11
3x+2(-3x+11)=7
==>-3x=7-22
==>-3x=-15
==>x=5
y=-3*5+11=-4
Answer D
The population model is an exponential decay because it decreases
The exponential model of the population is P = 3000(0.64^1/7)^t
<h3>How to determine the function?</h3>
The population decreases by 0.36 every 7 years.
This means that the function is an exponential decay.
An exponential decay function is represented as:
P = a((1 - r)^1/n)^t
Where:
- a represents the initial value (3000)
- r represents the rate (0.36)
- n represents the number of years the population decreases (7)
- P and t are the variables
So, we have:
P = 3000((1 - 0.36)^1/7)^t
Evaluate the difference
P = 3000(0.64^1/7)^t
Hence, the exponential model of the population is P = 3000(0.64^1/7)^t

Minus 2 1/2 from 17 1/2. then divide the answer by 5
25/60 = 0.42 hours
65/0.42 = 156 people per hour
156 *3 = 468 people in 3 hours
The correct answers are:
