Question

Help?
Write an inequality for its exterior.

Answer 1

write the equation of this elipse first..

Answer 2

\[(y^2/169) +x^2/25) = 1 \]

Answer 3

true.. now whenever y^2/169 + x^2/25 > 1 .. the point is x,y is outside the elipse.
so your inequality would be y^2/169 + x^2/25 > 1..

also worth nothing.. y^2/169 + x^2/25 < 1 .. when the ineq is this, the point lies inside the elipse..
this is true for any curve.. for a circle, hyperbola, elipse..

Answer 4

Oh okay. Thanks!

Answer 5

You're welcome. :)
