8 0

Answer:

x ≈ 6.8

Step-by-step explanation:

since all angles in a triangle add up to 180º:

8x-4+17x-23+3x+17=180

28x-10=180

28x=190

x ≈ 6.8

hat is the average rate of change of f(x), represented by the table of values, over the interval [-2, 3]? x f(x) -6 2.5 -2 2.5 0
vodomira [7]
Your table of values is so difficult to read that many of us helpers would just skip your post.

<span>x f(x) -6 2.5 -2 2.5 0 2 2 0 3 5 5 2.5 1 0.5</span>  could be put into far clearer format as follows:

 x   f(x)
--  -----
-6  2.5
-2  2.5
and so on.  Please fix it.

The "average rate of change" formula is 

                  f(x2) - f(x1)
av r of c = ---------------
                     x2-x1

so if you go from (-6, 2.5) to (2.5, 10.5), the av r of c would be
                  
                 10.5 - 2.5            9        18
             ------------------ = -------- = -----
                 2.5-(-6)            8.5         17

This may or may not be your final answer.  Again, please put your data table into readable form and then find the av r of c over the interval [-2,3].
