<h3>
Answer: Choice C) 31</h3>
==============================================
Explanation:
The recursive rule
f(n+1)=f(n)-3
can be rearranged to
f(n) = f(n+1)+3
after adding 3 to both sides
----------------
Now let's say we plug in n = 3
f(n) = f(n+1)+3
f(3) = f(3+1)+3
f(3) = f(4)+3
f(3) = 22+3
f(3) = 25
Repeat for n = 2
f(n) = f(n+1)+3
f(2) = f(2+1)+3
f(2) = f(3)+3
f(2) = 25+3
f(2) = 28
Each time we keep adding 3 to get the previous term (since the original recursive rule says to subtract 3 to get the next term; we just go backwards of what the instructions say).
Lastly, we can find that f(1) = f(2)+3 = 28+3 = 31 making the answer to be choice C.
If the greatest value of m can only be less than 9, then m<9 is the correct choice.
Answer:
to what?
Step-by-step explanation:
Answer:
A. Would be your answer
Step-by-step explanation:
7 plus a number n is 7+n, so B and D are already incorrect.
The phrase “and then multiply” suggests parenthesis be around the numbers/variables you would need to do first, so that excludes C.
Making A. your only answer left
