36P2
smaller example: say 4 people are running for office, A,B,C, and D
first way: A is prez, B is vice
second way: A is prez, C is vice
Let;'smakeit simpler
A, B
A,C
A, D
B, A
B, C
B, D
C, A
... get it?
Now we don't wantto do that with 36 people so we do some math
Let's say we order four people; A, B,C, D
at first we have 4 choices for 1st. Once we pick a 1st, we have 3 to choose from. 4 1stpicks, from that there can be 3 2nd picks, so thetotal so far is 4*3. Once 2nd is picked, there are 2 choices for 3rd; 4*3*2. And only one choice for the lastplace; 4*3*2*1
For 36 people, we have 36 choices for prez, that leaved 35 choices for vice. but here, thank goodness, we are only picking two places; prez and vice. So we can stop there. You shoid be able to figure out what to do based on the example I gave
Answer:
The system is dependent:
x=-3t-7
y=-5t-15
z=t
Step-by-step explanation:
I chose to use a matrix to solve this system of equations. Once put into matrix form, you need to row reduce the system into its simplest form (Row Reduced Echelon form). Doing this, we find that the system is dependent on the z variable. And following usual procedures, we let z equal some other letter; which is t in this case. Then we isolate each variable to get the answer.
