Answer:

2) y = x - 4

y = -x + 2

=> x - 4 = -x + 2

=> 2x = -6

=> x = -3

=> y = -3 - 4 = -7

3) y = 3x + 1

y = 5x - 3

=> 3x + 1 = 5x - 3

=> 2x = 4

=> x = 2

=> y = 3(2) + 1 = 7

4) 2x + y = 8 => y = -2x + 8

y = x - 7

=> -2x + 8 = x - 7

=> 3x = 15

=> x = 5

=> y = 5 - 7 = -2

Form the quadratic equation whose one root is 2 + 2^(1/2)

Oksanka [162]

9514 1404 393

Answer:

x^2 -4x +2 = 0

Step-by-step explanation:

The other root is the conjugate of the given one, so is 2-√2. The quadratic equation in factored form is then ...

(x -2-√2)(x -2+√2) = 0

Expanding this, we get ...

(x -2)^2 -(√2)^2 = 0

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

x^2 -4x +2 = 0 . . . . the equation you're looking for

Ainat [17]

The answer would be the first one or 3y2, this is because it goes into each term evenly enough to simplify it.
