Answer:
x=-4
Step-by-step explanation:
Subtract x from 3x ( 2x )
2x+5=-3
Subtract 5 from -3 ( -8 )
2x=-8
Divide ( -4 )
x=-4
Answer:
{(3,6),(2,1),(-8,4),(2,0)}
Step-by-step explanation:
when determining if a set of points is a function
determine if any of the x values or y values repeat. if they do then it is not a function because it will not pass the function like test. (which is where you can draw a line trough the function and it will hit more than once.
none if the x values repeat and none if the y values do either.
x values : 3,2,-8,2
y values: 6,1,4,0
I think the correct answer would be the second option. Given the data above, the type of association that the scatter plot would show would be a positive linear association. It is best if you plot these points so you will see that there is an almost linear relation of the points. By doing linear regression, you can validate that the correlation of the data points would be linear. A positive linear association would mean that it changes linearly from the left increasing to the right. So, most likely, the graph would be sloping up to the right and it can be observed for the given data above.
