Answer:
-3
Step-by-step explanation:
A = midpoint
-17 + 5 = -12
-12/2 = -6 = A
-6 + 0 = -6
-6/2 = -3 = B
For this case we have:
By properties of the radicals 
So:
.
Now, for power properties we have:

Thus, 
So:
in its radical form
Answer:
in its simplest form.
in its radical form
Answer:
A.
Step-by-step explanation:
The graph of the y-axis would be x=0
Take two points from both functions. You
will find out that both slopes are the same.
Also you can see that the functions have different y-intercepts.
If the functions have the same slope but different y-intercepts they are parallel to each other
I hope this helps
