Answer:
x=2, y=1
Step-by-step explanation:
4x+8y=16
4x-8y=0
Add the two equations together:
8x=16
Divide both sides by 8:
x=2
Plug this back into one of the original equations to find y:
4(2)-8y=0
8-8y=0
y=1
Hope this helps!
Answer:
76
Step-by-step explanation:
The discriminant is 
part of the quadratic formula.
a term is 3
b term is -10
c term is 2 (add it to the side of the 3 x squared minus 10 x)
Plug the values in!
(-10)^squared - 4(3)(2)
100-24 = 76
Answer:
