Answer:

Step-by-step explanation:
To find the average rate of change of a function over a given interval, basically you need to find the slope. The mathematical definition of the slope is very similar to the one we use every day. In mathematics, the slope is the relationship between the vertical and horizontal changes between two points on a surface or a line. In this sense, the slope can be found using the following expression:

So, the average rate of change of:

Over the interval 
Is:


Therefore, the average rate of change of this function over that interval is 3.
Answer: 9/14
Explanation. First, you have to find the least common denominator. The least common denominator is the lowest number you can use on the denominator to create a set of equivalent fractions
7 and 2 can both go into 14
Whatever number you use to multiply to equal 14, you do the same to the top.
It would look like this.
2/14 + 7/14
Then you add.
2/14 + 7/14= 9/14
You can’t simplify this fraction so this is your answer. Hope this helped!
If there is 4 thousands and 7 hundreds is 4,700
Answer:5 there is no and
6 is not definite
7 yes

7 they are lnverses
So, this problem asks us to construct an equation that relates the amount of money left to the amount of weeks that has gone by. First, let's assign variables. Let y be the amount of money left, while x is the number of weeks she receives money. The equation would be:
<em>y = 250 - 10x</em>
