Answer:

The solution is: x = -5.2, y = 11.2

Step-by-step explanation:

We are given the following system of equations:

-7x-2y = 14

6x + 6y = 18

Simplifying the second equation by three, we have that:

x + y = 6

y = 6 - x.

Replacing in the first equation:

-7x - 2(6 - x) = 14

-7x - 12 + 2x = 14

-5x = 26

5x = -26

x = -5.2

y = 6 - x = 6 - (-5.2) = 6 + 5.2 = 11.2

The solution is: x = -5.2, y = 11.2

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

Oksanka [162]

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

Find the value of X?

daser333 [38]

Because we know the midpoint is in the middle, we know that both sides are equal.
So set both = to each other
4x - 1 = 3x + 3

add 1 to both sides

4x=3x+4

then subtract 3x from both sides and because there is always a 1 in front of x the answer would be

x=4
