Answer:
Step-by-step explanation:
2x - y + z = 4
4x - 2y + 2z = 8
-x + 3y - z = 5
2x - y + z = 4
-x + 3y - z = 5
x + 2y = 9
4x - 2y + 2z = 8
-2x + 6y - 2z = 10
2x + 4y = 18
x + 2y = 9
2x + 4y = 18
-2x - 4y = -18
2x + 4y = 18
0 =0
infinitely many solutions
70,000
The 0 means that it stays the same.
Hope it helps.
Answer:
This is a geometric sequence because any term divided by the previous term is a constant called the common ratio. r=36/18=18/9=2 A geometric sequence is expressed as
\begin{gathered}a_n=ar^{n-1},\text{ where a=initial term, r=common ratio, n=term number}\\ \\ a_n=9(2^{n-1})\\ \\ a_6=9(2^5)\\ \\ a_6=288\end{gathered}an=arn−1, where a=initial term, r=common ratio, n=term numberan=9(2n−1)a6=9(25)a6=288
