Which system is equivalent to 3x^2 - 4y^2 = 25
Archy [21]

For this case we have the following system of equations:

3x ^ 2 - 4y ^ 2 = 25\\-6x ^ 2 - 2y ^ 2 = 11

We can write a system of equivalent equations.

For this, it is enough to multiply one of the two equations by a scalar.

Multiplying the equation 1 by 2, we have:

6x ^ 2 - 8y ^ 2 = 50

Therefore, the new system of equations is:

6x ^ 2 - 8y ^ 2 = 50\\-6x ^ 2 - 2y ^ 2 = 11

Answer:

A system that is equivalent is:

D) 6x ^ 2 - 8y ^ 2 = 50\\-6x ^ 2 - 2y ^ 2 = 11
