Answer:
Step-by-step explanation:
One is given the following function:
One is asked to evaluate the function for 
, substitute 
in place of 
, and simplify to evaluate:
A recursive formula is another method used to represent the formula of a sequence such that each term is expressed as a function of the last term in the sequence. In this case, one is asked to find the recursive formula of an arithmetic sequence: that is, a sequence of numbers where the difference between any two consecutive terms is constant. The following general formula is used to represent the recursive formula of an arithmetic sequence:
Where (
) is the evaluator term (
) represents the term before the evaluator term, and (d) represents the common difference (the result attained from subtracting two consecutive terms). In this case (and in the case for most arithmetic sequences), the common difference can be found in the standard formula of the function. It is the coefficient of the variable (n) or the input variable. Substitute this into the recursive formula, then rewrite the recursive formula such that it suits the needs of the given problem,
Answer:
A polynomial is factored completely when nothing else in the expression can be factored
Example:
x^2+3x-4 completely factored looks like (x+4)(x-1)
Answer: figures 1 and 3 i think

Answer:
50 people
Step-by-step explanation:
If you are to calculate the number of people that will come to the concert that will ensure option 1 and option 2 to yield equal amount
Let
x = number of people
Option 1:
Malcolm's Music Hall = 100 + 15x
Option 2:
Reggie's Reggae Room = 350 + 10x
Equate both options
100 + 15x = 350 + 10x
Collect like terms
100 - 350 = 10x - 15x
-250 = - 5x
x = -250/-5
x = 50 people
