Answer:
-45
Step-by-step explanation:
When the -4 is plugged in, it needs to be multiplied and then added to 39. That equals -45.
It’s 6x6=36, because if 4 over 2 was 4 twice then 6 over 2 is 6 twice.
The difference between 10, 17 and 24 is 7, so we can write 7n
To get from 7 to 10 you add 3.
This can be written as 7n+3
Substitute 46 into n
7(46)+3
=325
I hope this helps.

Answer:
Answer A: 300 n - 2200
Step-by-step explanation:
The profit function will be the income minus the cost of maintaining the boathouse.
The income comes from the number of boats that it docks (n) , times the monthly fee that each boat pays ($850), That is:
Income = 850 n
Now the monthly cost to operate the boathouse is the fix $2200 cost plus $550 per boat. That is:
2200 + 550 n
Now, the difference "Income - Cost" that defines the profit function becomes:
850 n - {2200 + 550 n} = 850 n - 550 n - 2200 = 300 n - 2200
