@MARC_

Answer 2

sry, i'm busy. maybe @Directrix can help u

Answer 3

its okay thank you

Answer 4

Try out the distance between two points calculator at this link.

http://www.mathwarehouse.com/calculators/distance-formula-calculator.php

The attachment shows you how the calculator looks.

I'll also post the distance formula if you decide you want to use it.

Answer 5

Let me know what you get from the calculator if you chose to use it, okay?

Attached is the distance formula if you prefer that.

Answer 6

ok ill use it give me one min

Answer 7

It just acted the fool with me. I don't know what's up. See what happens with your computer.

Answer 8

You can use simple distance/line/slope calculator:

Result is : The length of the segment AB: |AB| = 8.0623

Rounded to 10th is 8.1

Answer 9

@triangleguru has a better calculaor. Thanks.

Answer 10

To get the x-coordinate of the midpoint of the segment with endpoints (3,1) and (11,7), take the average of the two x-coordinates of the endpoints of the segment.

So, that would be what?

Answer 11

is it 7?

Answer 12

Let's see: (3+11)/2 = 14/2 = 7 YES, I agree.

Answer 13

On that third question, would you check to ensure that we are doing x-coordinate again?

Somehow, I expected the question to ask what is the y-coordinate?

Answer 14

were looking for the x-value

Answer 15

Okay, then do the same as on the previous question

Take the average of the two x-coordinates.

Answer 16

ok

Answer 17

Post what you get.

Answer 18

i got 6

Answer 19

Let's see. (3+9)/2 = 12/2 = 6. YES, I agree.

I have the midpoint formula attached in case you want to review it at some point.

Answer 20

thank you for your help!

Answer 21

You are welcome.
