D)x^2+y^2=625 X^2+(y50)^2=1122 Y=20 (15,20)(15,20)
E)x^2+y^2=625 X^2+y^2200y+10000=13618 Y=18 (20,15)(20,15)
1)Combine your answers from Parts D and E to pinpoint the epicenter of the earthquake
2)Graph the equations for all three stations to verify your algebraic solution.

you can graph the three circles at wolframalpha . com by typing
plot x^2+y^2=625, x^2+(y50)^2=1122, x^2+y^2200y+10000=13618
but they don't intersect in a common point. Not sure how to interpret the results.
