Answer is A
X-3/x^2-4 has two excluded values 2, -2
Answer:
x=-2, y=5. (-2, 5).
Step-by-step explanation:
15x-4y=-50
3x-2y=-16
---------------
15x-4y=-50
-5(3x-2y)=-5(-16)
------------------------
15x-4y=-50
-15x+10y=80
-------------------
6y=30
y=30/6
y=5
3x-2(5)=-16
3x-10=-16
3x=-16+10
3x=-6
x=-6/3
x=-2
It would be a 50/50 chance, because there is only two different things it could land on, and for each there is a 50% chance for it to land on that side so.
