X + y = 6
x - 6y = -9

Subtract the equations, you get:

y - (-6y) = 6 - (-9)
7y = 15

y = 15/7

x + 15/7 = 6
x + 15/7 = 42/7
x = (42-15)/7
x = 27/15

None of your answer choices are correct, since the solution to the systems of equation is (27/15, 15/7)

Find the sum of the geometric series 9000-900 +...+ 0.009

bagirrra123 [75]

Based on the calculations, the sum of this geometric series is equal to 9,990.

<h3>The standard form of a geometric series.</h3>

Mathematically, the standard form of a geometric series can be represented by the following expression:

$\sum^{n-1}_{k=0}a_1(r)^k$

Where:

a₁ is the first term of a geometric series.

r is the common ratio.

<h3>How to calculate the sum of a geometric series?</h3>

Also, the sum of a geometric series is given by this mathematical expression:

$S=\frac{a_1(1-r^n)}{1-r}$

<u>Given the following data:</u>

First term, a = 9000.

Common ratio, r = 900/9000 = 0.1

Substituting the given parameters into the formula, we have;

$S=\frac{9000(1-0.1^3)}{1-0.1}\\\\S=\frac{9000(1-0.001)}{1-0.1}$

S = 9000(0.999)/0.9

S = 8,991/0.9

S = 9,990.
