Answer:

O equivalent by the associative property of addition

Step-by-step explanation:

Associative Property = a property of some binary operations, which means that rearranging the parentheses in an expression will not change the result

Which means that you can change the expression 25x - (6x+12) without changing the answer. So, the changed result would be (25x-6x) + 12.

If the tank is then field to capacity how many half-gallon bottles how many cords will it make?

lukranit [14]

Answer:

Divide 12 by 4 first to figure out how many gallons are in each 1/4 of the tank.

12/4=3

So if I added another 1/4 to the capacity:

It could hold 15 gallons.

All you have to do to find how many half bottles can be filled is to times 15 by two since we are filling half gallon bottles.

15x2=30

30 bottles.

The Demand function for a product is given by:

VikaD [51]

Answer:

The average rate of change of Demand between 40 and 175 units sold is of -0.1045.

Step-by-step explanation:

Average rate of change:

The average rate of a function f(x) in an interval [a,b] is given by:

$A = \frac{f(b) - f(a)}{b - a}$

In this question:

$D(q) = -0.0003q^2 - 0.04q + 23.56$

What is the average rate of change of Demand between 40 and 175 units sold?

$a = 40, b = 175$ . So

$D(40) = -0.0003*40^2 - 0.04*40 + 23.56 = 21.48$

$D(175) = -0.0003*175^2 - 0.04*175 + 23.56 = 7.3725$

$A = \frac{f(b) - f(a)}{b - a} = \frac{7.3725 - 21.48}{175 - 40} = -0.1045$

The average rate of change of Demand between 40 and 175 units sold is of -0.1045.
