Answer:
-9
Step-by-step explanation:
We are summing the 3rd 4th and 5th terms because k goes from 3 to 5
The third term is
-2(3) +5 = -6+5 = -1
The fourth term is
-2(4) + 5 = -8+5 = -3
The fifth term is
-2(5) +5 = -10 +5 = -5
Add these 3 terms together
-1+-3+-5 = -9

Answer:
= - 3n - 3
Step-by-step explanation:
The nth term of an arithmetic sequence is
= a₁ + (n - 1)d
where a₁ is the first term and d the common difference
Here a₁ = - 6 and d = a₂ - a₁ = - 9 - (- 6) = - 9 + 6 = - 3 , then
= - 6 - 3(n - 1) = - 6 - 3n + 3 = - 3n - 3
Answer:
Each month Manuel reads 6 novels so you get
n = 6mn=6m
If you plug in 13 for m we get
n = 6(13) = 78n=6(13)=78
Manuel needs to read 78 novels in 13 months.
Set B has 2 of the same Y values which makes it not a function.
