Step-by-step explanation:
<u>Answer:</u>
(x, y) = (-2, 2)
<u>Step-by-step explanation:</u>
We are given the following two equations which we are to solve using the substitution method:
--- (1)
--- (2)
From equation (1):
Substituting this value of x in (2) to get:
![x = [tex]x - 2y = -6\\\\(y-4)-2y=-6\\\\-y=-6+4\\\\-y=-2](https://tex.z-dn.net/?f=x%20%3D%20%5Btex%5Dx%20-%202y%20%3D%20-6%5C%5C%5C%5C%28y-4%29-2y%3D-6%5C%5C%5C%5C-y%3D-6%2B4%5C%5C%5C%5C-y%3D-2)
[/tex]
y = 2
Substituting the value of y in (1) to get x:
x = -2
Therefore, (x, y) = (-2, 2).
Answer:
Following are the solution to this question:
Step-by-step explanation:
For this set, the correlation coefficient is = -0.015.
It shows that financial variables have trust issues. Once a price rises, the other one is decreasing the value of -0,015 shows, that there are several fewer associations in the set of data among x and y and between y values. This interaction also can range between -1 to 1, to 0 being completely unrelated. But you'd never be sure, in this situation, 0.015 is very similar to 0.
It means that your prediction is nothing better than just a wild choice. Its odds of an estimated value being relatively close to the actual result are therefore much smaller as the points are it's hardly the best match.
Answer:
the slope is 4/3
Step-by-step explanation:
use the formula:
m=
where x1 and y1 can be any point and x2 and y2 can be any point.
I used the last relation as my x1,y1 and second last relation as my x2,y2 because it is easier to subtract them.
which is 8/6 or 4/3
