The answer is x = 17, hope this helps :)
By definition <span>the average rate of change is given by:
</span>

<span>We have the following function:
</span>

We evaluate the function for the given interval:
For X = 1:

For X = 5:

Then, replacing values we have:
Answer:
<span>
the average rate of change in f(x) over the interval [1,5] is:

Answer:
The equation of line with slope -7 passing through (5,9) in point-slope form is:

Step-by-step explanation:
Given
Slope of line = m = -7
Point = (5,9)
The point slope form of equation is obtained from a point and slope. It is given by the equation:

We know that (x1,y1) = (5,9)
Putting the values we get

Hence,
The equation of line with slope -7 passing through (5,9) in point-slope form is:
