Given:
The system of equation is:
To find:
The solution of the given system of equations.
Solution:
We have,
...(i)
...(ii)
Add (i) and (ii) to eliminate the variable x.
Putting in (ii), we get
Divide both sides by 2.
Therefore, the solution of given system of equations is (0,4). Hence, the correct option is A.

Given:
The geometric sequence is:
To find:
The 9th term of the given geometric sequence.
Solution:
We have,
Here, the first term is:
The common ratio is:
The nth term of a geometric sequence is:
Where, a is the first term and r is the common ratio.
Substitute to find the 9th term.
Therefore, the 9th term of the given geometric sequence is 5103.
