With the provided vertices and the focus point, the hyperbola will look like the one in the picture below.
notice the "c" distance from the center to the focus point.
since it's a vertical hyperbola, the positive fraction will be the one with the "y" in it, its center is clearly half-way between the vertices at -5, 5.
its major axis or traverse axis goes from -2 up to 12, so is 14 units long, therefore the "a" component is half that, or 7.
Answer:
D
Step-by-step explanation:
D is not a function because it has repeated x values. If you do the vertical line test, it intersects the graph multiple times. Hence, it is not a function.
Thank you for coming to Brainly with your questions!
I believe the answer is:
B. Straight. because the line is 180 degrees, in other words "straight".
I hope this helps you! Please mark Brainliest! Lemme know if I can help with any further questions!

For your first answer z=60 because 360/6
For your second answer y=128 you must add the two sides then subtract the answer from 360 to get 128
For your third answer for x=120 and 2x=100
