So the associative property is basically as long as it's addition or multiplication,  you can move around the groupings and it will still be the same.


For example, you can say:(21 * 7) (3x)  instead of (21)(7)(3x)


And it would be equal to the old version.


(To answer your other question, the commutative property is you can move around all the parts of the equation as long as it's addition or multiplication.)


So basically, it would be the first one you sent me.

Ehh, now it's letting me answer.

A point lies on AB and is the distance from A to B. Point A is located at (4, 8) and point B is located at (14, 10)
Rzqust [24]

Answer:

(9,9)

Step-by-step explanation:

Assuming the point is exactly halfway between A and B, to find it we just need to find the centre point between (4,8) and (14,10).

To find the midpoint, we just need to find the middle value, by dividing the difference between the x values by 2, and repeating the process with the y values.

This is because the point is in the middle, so it's y value will be in the middle of the given AB y values, and its x value will also be directly in the middle of the AB x values.

The x values are 4 and 14. The midpoint is

14-4=10

10/2=5 (the midpoint is 5 away from each reference point)

4+5=9

The midpoint is 9 for the x values. This means the x-value for the point is 9.

Repeat for y-values:

10-8=2

2/2=1

8+1=9

The midpoint is 9, therefore it has the y coordinate of 9.

Therefore the coordinates for the point are (9,9).

Hope this helped!

Pleaseee help. Oh yeah this has to be 20 characters soooo

It is more than one I think because it becomes -1 over -12 WITHOUT the -power and then add the power and it becomes positive. Make the power positive and it will become negative making it less than 1.
