Answer:

The answer will be Y*(6*5)

Step-by-step explanation:

Find the points of intersection of the equation: xy=2 and x+y =4
Blizzard [7]

Answer:\Large\boxed{(2+\sqrt{2},~2-\sqrt{x} )~~and~~ (2-\sqrt{2},~2+\sqrt{x} )}

Step-by-step explanation:

<u>Given the system of equations</u>

1)~xy=2

2)~x+y=4

<u>Divide x on both sides of the 1) equation</u>

xy=2

xy\div x=2\div x

y=\dfrac{2}{x}

<u>Current system</u>

1)~y=\dfrac{2}{x}

2)~x+y=4

<u>Substitute the 1) equation into the 2) equation</u>

x+(\dfrac{2}{x} )=4

<u>Multiply x on both sides</u>

x\times x+\dfrac{2}{x}\times x=4\times x

x^2+2=4x

<u>Subtract 4x on both sides</u>

x^2+2-4x=4x-4x

x^2-4x+2=0

<u>Use the quadratic formula to solve for the x value</u>

x=\dfrac{-(-4)\pm\sqrt{(-4)^2-4(1)(2)} }{2(1)}

x=2\pm\sqrt{2}

<u>Substitute the x value into one of the equations to find the y value</u>

xy=2

(2+\sqrt{2} )y=2

y=2-\sqrt{2}

OR

xy=2

(2-\sqrt{2} )y=2

y=2+\sqrt{2}

Therefore, the points of intersection are

\Large\boxed{(2+\sqrt{2},~2-\sqrt{x} )~~and~~ (2-\sqrt{2},~2+\sqrt{x} )}

Hope this helps!! :)
