Answer:
Option C (1, 0)
Step-by-step explanation:
We have a system with the following equations:

The first equation is a parabola.
The second equation is a straight line
To solve the system, substitute the second equation in the first and solve for x.

Simplify

You must search for two numbers that when you add them, obtain as a result -2 and multiplying both results in 1.
These numbers are -1 and -1
Therefore

Finally the solutions are

Answer:
4/6 or 2/3...............
I can't read that language but I'll guess it says write a second degree equation then solve for n when d=10.



Answer: n² - 3n - 20 = 0
That doesn't factor so there is no integer n solution.
That means there are no polygons with 10 diagonals.
