Question

@vocaloid Can you help me please?

Answer 1

any ideas?

Answer 2

I was thinking option D.

Answer 3

not quite

Answer 4

first step is to find our h,k,a,b values

Answer 5

I was thinking that it might be B too.

Answer 6

h and k = 0 since it's at the origin

Answer 7

Okay.

Answer 8

the vertex equation is

(h +- a, k)

since our vertex is (-6,0) our a value is -6

Answer 9

and since the co-vertex is (h, k +-b)

the b value is 4

Answer 10

so, given that a = -6 and b = 4

and the equation of an ellipse at the origin is

x^2/a^2 + y^2/b^2 = 1

Answer 11

Wouldn't I then multiply 6^2 and 4^2?

Answer 12

what do you think the equation is?

Answer 13

yes, 6^2 and 4^2 give us 36 and 16

Answer 14

Option C? Because 6^2 = 36 and 4^2 = 16 and a=6 and b=4

Answer 15

good!

Answer 16

anything else?

Answer 17

Can you check an answer for me?

Answer 18

sure, just open a new post
