Answer:
A
Step-by-step explanation:
Remember that the x-value of the vertex when an equation is given in standard form can be found with the equation
. So, we can take the coefficients from the equation and plug them in.

Now we know that the x-value of the vertex is 8. Next, the equation for the y-value is
, where h is the x-value of the vertex (8).

So the vertex is (8,-1).
Finally, the axis of symmetry is the x-value of the vertex, also called h.
Final answer, vertex: (8,-1) and axis of symmetry: x=8

Step-by-step explanation:
Answer:
TC (A) = 40x , TC (B) = 500 + 20x
Step-by-step explanation:
Let the number of students be = x
Hall A Total Cost
Relationship Equation, where TC (A) = f (students) = f (x) 40 per person (student) = 40x
Hall B Total Cost
Relationship Equation, where TC (B) = f (students) = f (x) 500 fix fee & 20 per person (student) = 500 + 20x
