<span>2n^2 - 7n - 3 = 0
a = 2
b = -7
c =-3
Then use the Quadratic formula:
x = [-b +-sqroot(b^2 -4*a*c)] / 2*a

Answer:
Step-by-step explanation:
+ we take t- number of tickets and each ticket cost $7.
So t is too the number of people who buy tickets, then
![0\leq t\leq 200](https://tex.z-dn.net/?f=0%5Cleq%20t%5Cleq%20200)
A) We can calculate the amount of money: M= 7t where ![0\leq t\leq 200](https://tex.z-dn.net/?f=0%5Cleq%20t%5Cleq%20200)
B) The domain for t is
, t is an integer.
C) The range for the amount M:
![0*7\leq M\leq 200*7\\0\leq M\leq 1400](https://tex.z-dn.net/?f=0%2A7%5Cleq%20M%5Cleq%20200%2A7%5C%5C0%5Cleq%20M%5Cleq%201400)
Answer: Point D is at (-5,2) as the first coordinate is on the "X" axis, and the second coordinate is on the "Y" axis. You would move down the x axis first going 5 to the left, as that would be negative. Then two up as that is positive on the y axis! Hope this Helps!
