Answer: X is equal to 8 and Y is equal to 3
Answer:
168
Step-by-step explanation:
The first equation given is 
Where a is number of adult tickets and b is number of student tickets
It is also given that 82 students attended, so we can put "82" in place of "b" and then solve the equation for a:

Hence, 168 adults attended

Answer:
y = 1(x - 5)² + 3
Step-by-step explanation:
The general formula of a quadratic equation is written as;
y = a(x − h)² + k
Where (h, k) are the x and y coordinates at the vertex.
Our vertex coordinate is (5, 3)
Thus;
y = a(x - 5)² + 3
Now,we are given another coordinate as (8, 12)
Thus;
12 = a(8 - 5)² + 3
12 = 9a + 3
9a = 12 - 3
9a = 9
a = 9/9
a = 1
Thus,the equation is;
y = 1(x - 5)² + 3
The h is 8. The answer is true!
