Answer:

Step-by-step explanation:
Given


Required
Find S
Midpoint is calculated as:

So, we have:

<em>Where x2 and y2 are the coordinates of S</em>
Multiply through by 2



By comparison:




So:

Answer:
second option: product is irrational because both are irrational
Step-by-step explanation:
Answer:
You can use Gaussian Elimination.
Double both sides of the first equation and add the second equation.
6x + 4y = 8
5x - 4y = 3
---------------
11x = 11
x = 1
5 - 4y = 3
-4y = -2
y = 1/2
Step-by-step explanation:
Answer:
Yes, because it can written as a ratio of integers
Step-by-step explanation:
0.12785 = 12785/100,000
