Step-by-step explanation:
not sure what this question is asking completely but it will most likely be y= -2x+4 because it mirrors the line across the y axis. as you can see in the image, the one with slope of -2 is the only one going from top left to bottom right.
Answer:
P(n)=5n+9
Step-by-step explanation:
The initial population (week 0),
Population after 5 weeks,
Since the population is growing according to a linear growth model.
A linear model is of the form: y=mx+b where m is the slope and b is the y-intercept.
First, we determine the population growth per week which is our slope.
We then have:
y=5n+b
When Number of weeks, n=0, =y=9
Therefore: 9=5(0)+b
b=9
Therefore, our population after n weeks:
P(n)=5n+9
