Answer: or (1,1)
Step-by-step explanation:
You can apply the Method of substitution.
Knowing that (second equation), you can substitute it into the first equation and solve for the variable y:
Now you need to substitute into the second equation to calculate the value of the variable x. Then:
Then, the solution is:
or (1,1)

Answer:
B
Step-by-step explanation:
This is a geometric sequence with common ratio r and n th term
= a
where a is the first term
r = =
r = = =
The first term a =
= ×
[ Note × = 2 ], hence
= 2 × 2 × 2 × 2 = 16
⇒ = 16 → B
