The answer is a.0
Concentric means these circles would have the same center, thus, the smaller circle must be inside the bigger circle. Any tangent line to the smaller circle wont be a tangent line to the bigger circle, since that tangent line would intersect at the bigger circle at 2 points. Any tangent line to the big circle will not touch the small circle... so the answer would be 0.
Step-by-step explanation:
the vertical line test means if there are more than one point on a vertical line then it is not a fuction
i cant answer without seeing the graph but i hope this helps

Answer: 
Step-by-step explanation:
1. As you can see, 
is equal to the other quadratic equation 
.
2. Then, this would the same as write the quadratic equations as following:
3. And then set them equal to each other, as you can see below:
Substituting, you obtain:
3. Keeping the above on mind, you can set up the given equations as a system of equations as folllowing:
Answer:
-14 = n
Step-by-step explanation:
56 = -4n
Divide each side by -4
56/-4 = -4n/-4
-14 = n
