Question

P (x,y) is 6 units from A (0,0) and 9 units from B (9,0). Find x and y.

Answer 1

you have two equations from this
by pythagoras \[x^2+y^2=6^2\] which says \((x,y)\) is 6 units from \((0,0)\)

Answer 2

if it is 9 units from \((9,0)\) then \((x-9)^2+y^2=9^2\)
now you can solve this \[x^2+y^2=36\\
(x-9)^2+y^2=81\]

Answer 3

How do you solve it after that?

Answer 4

@satellite73

Answer 5

idk i didn't do it
probably subsitution

Answer 6

for example first one says \(y^2=36-x^2\) so you can substitute that in to the second equation and solve \[(x-9)^2+36-x^2=81\]

Answer 7

Okay thank you! @satellite73
