Urgent please help with finding rate of change
boyakko [2]

When working with functions (of all types), the average rate of change is expressed using function notation:

\dfrac{f(b)-f(a)}{b-a}.

For the interval from x=7 to x=8,

1. find f(7) and f(8):

  • f(7)=729\cdot 3=2187;
  • f(8)=2187\cdot 3=6561;

2. use given formula:

\dfrac{f(8)-f(7)}{8-7}=\dfrac{6561-2187}{8-7}=4374.

Answer: the average rate of change for the interval from x=7 to x=8 is 4374.

A restaurant supplier receives a discount on each oven purchased. The original price of each oven is x dollars. The restaurant s
Sauron [17]

Answer:

Each oven is discounted by $20.

Step-by-step explanation:

Original price of oven in dollars  = x

To find total cost for 9 such ovens without discount we will apply unitary method.

If 1 oven costs in dollars = x

Then 9 ovens will cost in dollars = 9x

The ovens are purchased by a restaurant supplier at some discounted price.

The new price after discount in dollars = 9x-180

We see that the total cost of 9 ovens which was originally =9x has been decreased to =9x-180 after discount.

The decrease amount is the discount amount on 9 ovens which is = $180

To find discount offered on each oven, we will again use unitary method.

Discount on 9 ovens = $180

∴ Discount on 1 oven = \frac{\$180}{9}=\$20

∴ Each oven is discounted by $20.

How you would solve this problem. 3n=15
Sergio [31]

Answer: n=5

Step-by-step explanation: You are solving for ‘n’ so you would want to get ‘n’ by itself on one side of the equation. The easiest way to do this would be to divide both sides by 3, which would make ‘3n’ turn to ‘n’ and 15 into 5.
