The average of 17 and 15 is 16 because if you add 17 and 15 together, and you divide them by 2, you get 16.
For this case we must find
By definition we have to:
We have the following functions:
Now, applying the given definition, we have:
Answer:
In a 45-45-90 triangle, both of the legs have the same length and the ratio of one leg to the hypotenuse is 1:sqrt(2).
The answer in b next time make sure the picture is clear
Y=2/3x -5/2
Slope is equal to the parallel line (2/3)
Find y intercept by setting y and x equal the given coordinates and solve.
