2x = 4y + 8, x - 2y = 4

Evgen [1.6K]

Answer: x = 8, y = 2, coordinates (8,2)

Step-by-step explanation:

2x = 4y + 8 (divide by 2 to get value of x)

x = 2y + 4

(now substitute x into the second equation to find value of y)

2y + 4 - 2y = 4

2y - 2y = 4 - 4 (divide by 2 to get value of y)

y - y = 2 - 2

y = 2

Now plug in value of "y" to get value of "x".

x - 2(2) = 4

x - 4 = 4

x = 8

Coordinates (8,2)

Step-by-step explanation:

we know that

A geometric sequence, is a sequence of numbers where each term after the first is found by multiplying the previous one by a fixed, non-zero number called the common ratio.

$a_n=r^{n-1}$

where

a_n----> $n^{th}$ term of the sequence

r ---> is the common ratio

a ---> the first term of the sequence

$a=50\\r=100\%-10\%=90\%=90/100=0.90$

substitute

$a_n=50(0.90)^{n-1}$

For n=12

substitute

$a_n=50(0.90)^{12-1}=16$
