Answer:
13
Step-by-step explanation:
Firstly we would start off by simplifying the equation by doing the order of operations backward (PEMDAS -> SADMEP) and multiply -4 and -3 which would equal a positive 12
Next, we would divide 12 and -6 and get a negative 2
Finally, we would have the equation 1 - 12 + (-2)
We would solve the equation to get -13/(-1)³
This would make the -13 into a positive since any number over one is a whole number. -13 is getting divided by (-1) 3 times so it converts to a positive, then a negative, then back to a positive.
I hope this helped :3
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
Answer:
c. (y + z = 6) ⋅ −3
Step-by-step explanation:
We want to use elimination to eliminate y in a system of equations
y + z = 6
3y + 4z = 1
We can take the first equation and multiply by -3 to make the y term -3 so when we add the equations -3y + 3y =0
-3(y + z = 6)
3y + 4z = 1
--------------------
-3y -3z = -18
3y + 4z = 1
---------------------
0y +z = -17
13x-8+7x+4+3x
Combine like terms
23x-4
It can only be simplified. Without an equal sign (=), x cannot be found.
