Question

find the distance between the points (9,9) and (-7,-7)

Answer 1

Use the distance formula
\[\huge d=\sqrt{(x_2-x_1)^2+(y_2-y_1)^2}\]

Answer 2

(x1,y1)(x2,y2)

Answer 3

so how would I enter the values

Answer 4

\[\huge d=\sqrt{(-7-9)^2+(-7-9)^2}\]

Answer 5

ok

Answer 6

Yea....now solve that :)

Answer 7

why dont u solve it for him... Qualified helper O_O

Answer 8

I dont give the answers.

Answer 10

Really? That's all I look for 90% of the time

Answer 11

@drkid15 have you solved it?

Answer 12

wouldnt it just be (-7 - 9) + (-7 - 9)? cause its sqrted?

Answer 13

d = -32?

Answer 14

is that the answer

Answer 15

im guessing so

Answer 16

is ur question multiple choice?

Answer 17

no

Answer 18

Why not try solving it yourself?

Answer 19

If you need help i can GUIDE you.

Answer 20

idk how

Answer 21

Im, 99% sure its -32, but I am blond... so I might be stupid

Answer 22

can u just guide me plz

Answer 23

Alright, so the equation is \[D = \sqrt{(x2-x1)^{2} + (y2 - y1)^{2}}\] right?

Answer 24

D is the distance between 9,9 and -7,-7

Answer 25

both of those sets have an x and a y its like this (x,y)

Answer 26

but since theres 2 sets, were gonna label it like (x1,y1) and (x2,y2)

Answer 27

Are you paying attention Drkid15?

Answer 28

yes

Answer 29

For the equations we have 9,9 as the first pair, so it takes over the x1 and y1

Answer 30

can u show me what it looks like when u enter the values

Answer 31

\[D = \sqrt{(9 - (-7))^{2} + (9 - (-7)^{2}}\]

Answer 32

By the way yes, the -32

Answer 33

thx

Answer 34

o wait no
