Answer:
A correlation coefficient of 0.02 indicates that the data are not correlated.
Step-by-step explanation:
0.02 is very close to zero and tells you that there is no linear relationship between the two variables.
Answer: 2 is not a function because 1 has no unique image
Step-by-step explanation:
I believe the slope of any vertical line is "undefined" because slope= rise(change in y values)/ run(change in x values).
Therefore, the slope for a horizontal line is
m= 0/(x2-x1).
However, for a vertical line the x-values are the values that are not changing. So, m= (y2-y1)/0. It is not possible to divide anything by zero. So, the slope of a vertical line is reported as m= undefined.
Any questions?
Answer:
Alway set your equations up with x first.
4x + 8 = x
-- x + 2 = x
4. x + 2 - 2 = x. is -2
You will always come up with the opposite of the last number in. × + 2
---- = x -2 so x is -2
-2
Step-by-step explanation:
The reason you do this, is what you do to 1 side you must do to the other side. This leaves you with
× = x-2, so x is -2
