Y = x + 2 is closest to what I believe is the solution.
If the club begins with 2 members, then +2 MUST appear in the formula.
If the club adds 2 members every week, then the total number of members would be
f(x) = y = 2 + 2(x-1), where x is the number of weeks.
Test this: If x = 1, then y = 2+2(1-1) = 2 + 0 = 2. This is correct. The club began with 2 members in week 1
Hello!if you mean 3.28 divided by 9.84 then the answer is 0.33333333 and so on
The answer is 3/2
3 units up and 2 units to the left that is the slope
Answer:
(x+1)(x-1)(x+3)(x-3)
Step-by-step explanation:
x4-10x^2+9
Group expression so that the coefficients of the x^2 terms add up to +9.
= x^4 -9x^2 - x^2+9
match coefficients in both groups
= x^4 -9x^2 - (x^2-9)
factor each group
= x^2 (x^2-9) - 1(x^2-9)
now factor out the common factor (x^2-9)
= (x^2-1)(x^2-9)
Finally, factor each quadratic factor
= (x+1)(x-1)(x+3)(x-3)
