B, if you distribute you get 2(times) 9x which is 18x and 2x-3 which is -6

so that would be 18x-6

A, B, & E


A because 16.4x + 1.6x equals 18x.

B and E require that you use te distributive property therefore 2 times 9x equals 18 x and 2 times -3 = -6. For E 6 times 3x = 18x and 6 times -1 = -6

Use the distributive property to remove the parentheses.<br> 10(u-2)
andrey2020 [161]

Answer:

After using distributive property to remove the parentheses 10(u-2)  we get 10u-20

Step-by-step explanation:

We need to use distributive property to remove the parentheses 10(u-2)

According to distributive property of multiplication over subtraction: a(b-c)=ab-ac

Using the above distributive property to solve the question. Multiply 10 with terms inside the bracket and solving:

10(u-2)\\=10u-10*2\\=10u-20

So, After using distributive property to remove the parentheses 10(u-2)  we get 10u-20

svetoff [14.1K]

The profit equation which relates P, profit to N, quantity produced and sold is:

P=17.75N-750

What is the total cost function?

The total production cost function, whereby total cost is C is as given below:

C=750+15.95N(look at a similar question provided)

What is the total revenue function?

The total revenue function is as given below:

R=33.70N

The profit is the excess of total revenue over total cost, in other words, profit is the total revenue minus total cost

P=33.70N-(750+15.95N)

P=33.70N-750-15.95N

P=33.70N-15.95N-750

P=17.75N-750

Please help! Problem is attached
Darya [45]

Answer:

  (a)  -3

Step-by-step explanation:

The value of f(x) approaches 3cos(π) = -3 as x approaches π from either direction. The limit is -3.

__

<em>Additional comment</em>

The fact that the function is defined to have a different value at x=π simply means there is a jump discontinuity there. The function is <em>not continuous</em>, because the limit and the function value differ. That doesn't detract from the fact that there is a limit, and it is -3.
