Answer: c. (3, 1)

Step-by-step explanation:

(3x - y = 8) + (3x + 3y = 12) = 6x + 2y = 20

Divide by 2

3x + y = 10

Plug in 3 for x

3(3) + y = 10

9 + y = 10

10 - 9 = 1

y = 1

f(1)=−8 f(n)=f(n−1)−3 Find an explicit formula for f(n)

Nat2105 [25]

Answer:

f(n) = -8 -3(n -1)

Step-by-step explanation:

The given recursive formula tells you that the difference between two sequential terms is -3, and that the first term is -8. This is a formula for an arithmetic sequence, so we can use the explicit formula ...

f(n) = a1 +d(n -1)

for a1 = -8 and d = -3.

f(n) = -8 -3(n -1)
