Answer:

The equation of the elipse is

$\frac{x^2}{169} + \frac{y^2}{25} = 1$

Step-by-step explanation:

Equation of an elipse:

The equation of a elipse with centre $(x_c,y_c)$ has the following format:

$\frac{(x - x_c)^2}{a^2} + \frac{(y - y_c)^2}{b^2} = 1$

Centre at (0,0):

Means that $(x_c,y_c) = (0,0)$ .

$\frac{x^2}{a^2} + \frac{y^2}{b^2} = 1$

Vertex at (13,0):

Vertex at 13 means that $a = 13, a^2 = 13^2 = 169$

Focus at (-12,0):

Means that $c = 12, c^2 = 12^2 = 144$

We have that:

$a^2 = b^2 + c^2$

$169 = b^2 + 144$

$b^2 = 25$

So, the equation of the elipse is

$\frac{x^2}{169} + \frac{y^2}{25} = 1$

Brums [2.3K]

Step-by-step explanation:

a-2=3+6a/3

By cross multiply

3(a-2)=3+6a

3a-6=3+6a

-6-3=6a-3a

-9=3a

a=-3
