Consider the following system of equations:
-1/3x^2 = -5/6 + 1/3y^2 and
5y^2 = 25/2 - 5x^2
How many solutions does the system have?

Respuesta :

Answer:

The system has infinitely solutions

Step-by-step explanation:

we have

[tex]-\frac{1}{3}x^{2}=-\frac{5}{6}+\frac{1}{3}y^{2}[/tex]

[tex]\frac{1}{3}x^{2}+\frac{1}{3}y^{2}=\frac{5}{6}[/tex]

Multiply by 3 both sides

[tex]x^{2}+y^{2}=\frac{5}{2}[/tex] ----> equation A

The equation A is a circle centered at origin with radius [tex]r=\sqrt{5/2}\ units[/tex]

and

[tex]5y^{2} =\frac{25}{2}-5x^{2}[/tex]

[tex]5x^{2}+5y^{2} =\frac{25}{2}[/tex]

Divide by 5 both sides

[tex]x^{2}+y^{2} =\frac{5}{2}[/tex] ----> equation B

The equation B is a circle centered at origin with radius [tex]r=\sqrt{5/2}\ units[/tex]

Equation A and Equation B are the same

Therefore

The system has infinitely solutions
