Answer:
y = 13x - 55
Step-by-step explanation:
So this is what we know
Selling price = $13 per copy
Expenses = $55
The formula for profit in this case is:
Profit = total selling price - expenses
In which y is the profit
The total selling price is 13x. x here is for the number of manuals she sells
The expenses are $55.
This then becomes y =13x - 55

Answer:
D.
Step-by-step explanation:
The point must be a critical point but it could be a saddle point. If the point is a saddle point it would not be neither a maximum nor a minimum. So it must be critical but it does not follow directly that it has a local maximum or local minimum.
Therefore D. (a,b) would be a candidate, but is not necessarily a maximum or minimum. It could be a saddle.
Answer:
The answer to your question is: -9y³ - 3y² + 5y - 9
Step-by-step explanation:
( y² - 3y³ - 2 + 5y ) - (7 + 8y² - 4y² + 6y³)
y² - 3y³ - 2 + 5y - 7 - 8y² + 4y² - 6y³
Like terms -3y³ - 6y³ + y² - 8y² + 4y² + 5y - 2 - 7
-9y³ - 3y² + 5y - 9
