the solution to the system of equation below is (−2, −1). 2x − 3y = −1 11x − 9y = −13 when the first equation is multiplied by −

Evgen [1.6K]

When the first equation is multiplied by -3, the sum of the two equation and any of the original equations will have the same solution as the original equations. Hence 5x = -10 and 11x - 9x = -13 will have a solution of (-2, -1).

Using the quadratic formula to solve 2x^2 = 4x – 7, what are the values of x?

LekaFEV [45]

For this case we have the following quadratic equation:

$2x ^ 2 = 4x - 7$

Rewriting the equation we have:

$2x ^ 2 - 4x + 7 = 0$

From here, we have:

$a=2 b = -4c = 7$

Substituting values in the quadratic equation we have:

$x = \frac{-b+/-\sqrt{b^2-4ac}}{2a}$

$x = \frac{-(-4)+/-\sqrt{(-4)^2-4(2)(7)}}{2(2)}$

Rewriting the equation we have:

$x = \frac{4+/-\sqrt{16-56}}{4}$

$x = \frac{4+/-\sqrt{-40}}{4}$

$x = \frac{4+/-\sqrt{-4*10}}{4}$

$x = \frac{4+/-2i\sqrt{*10}}{4}$

$x = \frac{2+/-i\sqrt{*10}}{2}$

Answer:

The values of x are given by:

$x = \frac{2+i\sqrt{*10}}{2}$

$x = \frac{2-i\sqrt{*10}}{2}$
