Answer :

You isolate x^2 which makes it x^2=9-y^2
Then you substitute that into the second equations which gives you answer C!

Answer:

(C)[tex]\frac{9-y^2}{25}-\frac{y^2}{36}=1[/tex]

Step-by-step explanation:

It is given that there is the system of the equations that are:

[tex]x^2+y^2=9[/tex]      (1)

and [tex]\frac{x^2}{25}-\frac{y^2}{36}=1[/tex]            (2)

Becca isolated [tex]x^2[/tex] from the equation (1) and substituted in equation (2), therefore

From the equation (1), we have

[tex]x^2=9-y^2[/tex]

Substituting this in equation (2), we get

[tex]\frac{9-y^2}{25}-\frac{y^2}{36}=1[/tex]

This is the resulting equation.

Thus, option C is correct.
