Question

For the points (0,0) and (x,-4) find x so that the distance between the points is 5.

Answer 1

\[\sqrt{(x-0)^2+(-4-0)^2}\]

Answer 2

=5

Answer 3

25=x^2+16

25-16=x^2
x^2=9
x=3

Answer 4

y answer ur own question? haha..

Answer 5

just checking it, i realized when i did it and check back it was correct but i already posted it so i said i will finish it

Answer 6

Hi pirplec16 ..
The work done by you is correct but not complete.
The answer is

\[\pm 3\]

Answer 7

what sgad says is true
x=3
or
x=-3

Answer 8

yeah i was wondering if i should put +/- three thanks myininaya!

Answer 9

\[Let A(x _{1};y _{1}) and B(x_{2};y_{2})\] be 2 points.Then,the distance between them is \[\sqrt{(x_{2}-x_{1})^{2}-(y_{2}-y_{1})^{2}}\]
