Answer:


Step-by-step explanation:
We are given that

We have to complete the recursive formula of f(n).
Substitute n=1






It forms geometric sequence because the ratio of two consecutive terms are equal.
Therefore, the recursive formula


Step-by-step explanation:
y = -9x - 45 -5
y = -9x - 50
slope = x coefficient = -9
we can use the point where
x = 0
y = -50
P1 (0, -50)
and when y = 0
-9x = 50
x = -50/9
P2 = (-50/9 , 0)
The number under 56 would be 3, the number under that would be 59, the number above 7 would be 42, the number to the right of 42 would be 98, the number under 10 would be 108. I think that's all of them, let me know if you have any questions :)
You would run 5mi and your friend would run 4mi. 5*8=40 and 4*10=40 40 the lowest shared factor.
300 because u have to dived and take away 50 from it
