Answer:
Exponential function.
Step-by-step explanation:
We have been given that the number of visitors to the Eiffel tower in Paris increase by 1.5% each year.
Since linear function changes at a constant rate and exponential function changes at a rate that's always proportional to the value of the function.
We can see that number of visitors is not changing at a constant rate. We can see that each next year number of visitors increased by 1.5%, so number of visitors is increasing exponentially.
Therefore, exponential function best models the relationship between time and the number of visitors to the Eiffel Tower.
K/3 + 4 -2k = -9k
First you add 9k to both sides
<span>k/3 + 4 -2k = -9k
</span> +9k +9k
<span>k/3 + 4 + 7k = 0
</span>
Now subtract 4 from both sides
k/3 + 4 + 7<span>k = 0
</span> -4 -4
k/3 + 7<span>k = -4
</span>
Now multiply 3 by both sides
k/3 + 7<span>k = -4
</span>x3 x3 x3
k +21k = -12
Now add k + 21k
22k = -12
Now divide both sides by 22
<span>22k = -12
</span>----- -----
22 22
k = -6/11
1 gallon equals 16 cups. So, 3 gallons equal 
cups.
So, 48 cups cost $13.92, which means that one cup costs
