Answer:
y = {-2, 6}
Step-by-step explanation:
The fastest help is afforded by a graphing calculator. It shows you the y-values at the points of intersection are -2 and +6.

-15×-5=75 I don't know of this helped but whatever
Answer:
$85
Step-by-step explanation:
5000 x $70 = $350,000
4950 x $71 = $351,450
4900 x $72 = $352,800
etc.
Create an equation for the monthly revenue:
f(n) = (5000 - 50n) x (70 + n)
= 350000 + 5000n - 3500n - 50n²
= 350000 + 1500n - 50n²
where n is the amount the ticket price is increased from $70.
Differentiate, equal to zero and solve for n to find the value of n when the monthly revenue is at its maximum:
f'(n) = 1500 - 100n
1500 - 100n = 0
1500 = 100n
15 = n
Therefore, the maximum monthly revenue is when n = 15.
So the cost of the ticket will be 70 + n = 70 + 15 = 85
Y = n^2 - 20n + 95
y - 95 = n^2 - 20n
y - 95 + 100 = n^2 - 20n + 100
y + 5 = (n - 10)^2
y = (n - 10)^2 - 5
answer is : G(n) = (n-10)^2 - 5
