Answer/Step-by-step explanation:
What do you mean by property?
I will guess for now, but if it is not right I will update it.
It would be the associative property since you are flipping the equation around.
Hope this helps :)

The cost of the file is $6.15 and the cost of the pen is $8.9
<h3>Solving word problems with systems of linear equations.</h3>
The interpretation of the given word problem leads to a system of linear equations.
From the given information:
- Let the file be denoted with f and the pen be denoted with p
f + 3p = 32.85 --- (1)
2f + 8p = 83.5 --- (2)
From equation (1)
f = - 3p+32.85
Replace the value of f in the above equation into equation (2)
2(-3p + 32.85) + 8p = 83.5
2p + 65.7 = 83.5
2p = 83.5 -65.7
2p = 17.8
p = 17.8/2
p = 8.9
Replacing the value of p = 8.9 into f = - 3p+32.85
f = -3(8.9)+32.85
f = 6.15
Therefore, we can conclude that the cost of the file is $6.15 and the cost of the pen is $8.9.

this function would count the profit of a month. To get the profit of longer periods you would need to do something like this:
[text]g(t) = t * f(n)[/text] where t is time.
I constructed the first function by simply looking at how much would one dog give profit. Since the fee is 500 and 200 of it is going to be spent away, 300 is left. So, profit from one dog is 300 dollars. However, if they don't have enough dogs, the doggy daycare company would get in debt because of 2000 dollars that it needs a month to operate, that's why I subtracted 2000 from the profit.
Answer:
x = - 3
Step-by-step explanation:
To find the zeros set f(x) = 0, that is
(x + 3)(x - 7)(x + 5) = 0
Equate each factor to zero and solve for x
x + 3 = 0 ⇒ x = - 3
x - 7 = 0 ⇒ x = 7
x + 5 = 0 ⇒ x = - 5
