Answer:
The sum of the first 8 terms in the series is 65535.
Step-by-step explanation:
We have,
The common ratio in a geometric series, r = 4
First term of GP is, a = 3
It is required to find the sum of the first 8 terms in the series. The sum of first n terms of a GP is given by :
Here, n = 8
So, the sum of the first 8 terms in the series is 65535.
102 times 4 =408
i know this because a square has 4 sides and i just need to multiply 102 and 4
3916 so estimated it will be 3900
Answer:
A
Step-by-step explanation:
<span>-7x + 2y = 0
6x + 6y = 0
</span><span>ordered pair: (−2,2)
the way to figure out if that ordered pair is a solution is pretty simple, you just plug the ordered pair into both equations, and check if the outcome is true.
</span>-7(-2) + 2(2) = 0
14 + 4 = 0
18 = 0 is NOT true, so this isn't a solution. still, check your second equation as well.
6x + 6y = 0
6(-2) + 6(2) = 0
-12 + 12 = 0
for this equation, it is a solution. however, because the solution must apply to the system as a whole, and not just one of the equations, the ordered pair still is not a solution.
