Answer:
2. 4a+2c = 5000
4. a + c = 1600
Step-by-step explanation:
5a + s = 2662
a + s = 1198
4a = 1464
a = 366
5(366) + s = 2,662
1830 adult tickets sold
2662 - 1830 = 832
832 student tickets sold
Since a(n)=-3(a(n-1)) the common ratio is -3, and a(1)=-3 so
a(n)=-3(-3^(n-1)) so the first four terms are:
-3, 9, -27, 81
Answer: 9
Step-by-step explanation:
Add 6m on both sides. Then divide by 3 on both sides. m=9
The answer is A. 2(-3)^4+2(-3)-17 = 139.
