The function is:

This is a linear function in the form:

where:

and

In this function:

The negative sign means the fish population is decreasing.

The number tells us the amount of decrease per month.

So the fish population is decreasing by:

The value is not the rate of change. It represents the starting fish population at the beginning of the year, when :

Therefore, the correct interpretation is:

So the correct answer is:

This situation can be modeled using a linear relationship because each sack has the same weight.

We are given:

After sacks are removed, the total weight is pounds.

After sacks are removed, the total weight is pounds.

From 3 sacks removed to 6 sacks removed, the number of removed sacks increases by:

During that time, the total weight decreases from pounds to pounds:

So removing 3 additional sacks decreases the total weight by 15 pounds.

Now divide to find the weight of one sack:

So each sack weighs:

Check:

If 3 more sacks are removed and each sack weighs 5 pounds, the total weight should decrease by:

This matches the given information.

The graph shows the queue size changing over time.

The horizontal axis represents:

The vertical axis represents:

The graph is a decreasing exponential curve. It starts near people and decreases quickly at first. Then the curve begins to flatten near:

A horizontal asymptote is the horizontal line that the graph approaches as time continues.

Here, the graph approaches the horizontal line:

This means that as time passes, the number of people in the virtual queue gets closer and closer to .

It does not mean the queue decreases to , because the graph levels off near , not near .

Therefore, the correct interpretation is:

The function f(n) gives the distance traveled by vehicle B.

The input n represents the distance traveled by vehicle A.

The problem says vehicle B travels 17 more than vehicle A. The phrase ''17 more than'' means we add 17 to the amount traveled by vehicle A.

So the relationship is:

f(n)=n+17

For example, if vehicle A traveled 50 miles, then vehicle B traveled:

f(50)=50+17=67

So the correct function is:

f(n)=n+17

Therefore, the correct answer is:

B

The graph compares the populations of two towns over time.

The horizontal axis represents:

The vertical axis represents:

The graph shows:

Town A as the solid blue line.

Town B as the dashed blue line.

To determine which town's population is growing faster, we compare the slopes of the two lines.

In Applied Algebra, the slope of a line represents the rate of change:

From the graph:

Now compare the growth rates:

So Town B's population is growing at a faster rate.

The values and describe starting populations, not growth rates. Since the question asks about growing at a faster rate, we must compare the slopes.
