do you know where is the center of the ellipse?
you need to compute only some distances.
draw a graph, that will help you

this graph does NOT correspond with the information you're giving.

anonymous · Answer

yes... your graph does not correspond with the conditions of the problem...

anonymous · Answer

these are the answer choices..

anonymous · Answer

your answer choice give equations for ellipses and hyperbolas.... do you know what conic section you have?

anonymous · Answer

I dont know what you mean

anonymous · Answer

would it be B?

anonymous · Answer

your posted question is about the vertices of an ellipse...
in your answer choices, you are given equations of ellipses and hyperbolas....
do you know the standard equation for an ellipse?

anonymous · Answer

No i do not

anonymous · Answer

ok... here's a good resource about conics... page 3.... http://tutorial.math.lamar.edu/pdf/Algebra_Cheat_Sheet.pdf

anonymous · Answer

Your answer choice matches with your post
( However the pic is the one matches with your previous post which so many solvers already guided you)

anonymous · Answer

Anyway, in this case: major axis a = 25, and minor axis b = 15

Do you want to learn some conic stuff at all?

anonymous · Answer

so I was correct?

anonymous · Answer

If your choice is B, so it's WRONG!

anonymous · Answer

what are you saying?? Is B right or wrong??!

anonymous · Answer

B IS WRONG!

anonymous · Answer

A?

Hint: this is horizontal ellipse!

anonymous · Answer

That's where your HUGE mistake, ellipse equation is the one with PLUS sign!

anonymous · Answer

d..

anonymous · Answer

I hope you know what you're talking about. Anyway you don't have any other choice!

anonymous · Answer

nooo it could be c
