C is the answer since you are trying to make the ys number (-/+) of the value the other y contains
(3) so you will multiply the first equation by -3 to be able to eliminate y
Answer:
Step-by-step explanation:
the answer is irrational hope this helps
Answer:
(5,5),(6,4),(-2,4) and (7,1)
Step-by-step explanation:
are concyclic
If the discriminant is 0, then you'll have exactly one root. This is a double root since the root repeats itself.
Example: y = (x-5)^2 = x^2-10x+25 has a double root at x = 5
