Answer: The average rate of change is 6.
First, plug in each value of <em>t</em> into the function, v(t) to find there coordinate pairs.
v(2) = (2)^2 - (2) + 10
v(2) = 4 + 8
v(2) = 12
v(5) = (5)^2 - (5) + 10
v(5) = 25 + 5
v(5) = 30
You can write these values as coordinate pairs, like so: (2, 12) and (5, 30).
The formula for the average rate of change is
. When you plug in the values from this particular case, the average rate of change formula becomes 
, or 
.
Looking at the equation, you can solve for the average rate of change between t = 2 and t = 5, which equals 6.

The number is -6.67
<em><u>Solution:</u></em>
Let "n" be the number
From given,
Given that,
Five less than 1/5 times a number is the same as the sum of the number and 1/3
Therefore, we get,
Thus the number is -6.67
