Simple system of equations problem,
m = member
n = nonmember
1m + 3n = 210
2m + 1n = 120
You can multiply the top equation by 2 to get:
2m + 6n = 420
2m + 1n = 120
Then you can subtract the two equations and the members will cancel out (2m - 2m = 0)
and get:
5n = 300 so dividing by 5 on both sides you get
n = 60
then you can plug in the value of 60 into one of the equations
2m + 1(60) = 120
So subtracting 60 u get
2m = 60
member = 30
nonmembers = 60
The Geometric Sequence Formula:
We have:
Substitute:
Answer:
It would roll in this direction.
Step-by-step explanation:
It would roll to the direction of maximum decrease, which is the -1 times the direction of maximum increase, which is given by the gradient of the function.
Since
For this case, the gradient of your function would be
And -1 times the gradient of your function would be
Then, at
So it would go towards
The magnitud of that vector is
and to conclude it would roll in this direction.
