Answer:
Vertex: (5, -9)
Step-by-step explanation:
fix = (x-8)(x-2)
fix = x^2 - 2x - 8x + 16
fix = x^2 - 10x + 16
a = 1, b = -10, and c = 16
To find vertex:
x = -b/2a
x = -(-10)/2(1)
x = 10/2
x = 5
y = 5^2 - 10(5) + 16
y = 25 -50 + 16
y = -9
Vertex: (5, -9)

Answer:
Adult tickets=275
Step-by-step explanation:
form 2 equations from the given info.
x+y=611
y=x+61
x being the adults and y being the students tickets
then substitute the y equation into the first equation.
x+x+61=611
2x+61=611
2x=550
x=275
and you can check by putting 275 back into the original equations :)
Lol, I am learning about this too!! The trick is to add 60 and 25. Meaning your answer is B. (85)
