You can find the answer by doing 4048 / 23 which is 176.
The question isnt coming up clearly like we cant see the full page do you think you could try to take amnother picture?
to find slope use 
which means the answer is -1
Hey there!!
Equation given :
... 78 = -2 ( m + 3 ) + m
... 78 = -2m - 6 + m
... 78 = -m - 6
... 78 + 6 = -m
... 84 = -m
... m = -84
Hope my answer helps!!
This is a problem dealing with permutations and combinations.
Order does not matter in this problem.
Since order doesn't matter, it is a combination.
Repetition matters, since you can't have the same person count as two people.
There are twelve slots.
_ _ _ _ _ _ _ _ _ _ _ _
Each slot needs to be multiplied by the next.
_*_*_*_*_*_*_*_*_*_*_*_
Now we have to fill in the slots.
Each slot will be filled with a number one less than the one before it. It has to be one less, since repetition matters.
The numbers will be decreasing from 30, since there are 30 possible people.
30 * 29 * 28 * 27 * 26 * 25 * 24 * 23 * 22 * 21 * 20 * 19
Multiply these numbers together and you get your answer.
