Mariulka [41]

Answer:

x = 8

Step-by-step explanation:

$\frac{x+7}{3} =\frac{2x+4}{4}$

do cross multiplication

$3(2x+4) = 4(x+7)\\6x + 12 = 4x + 28\\6x - 4x = 12 - 16\\2x = 16\\x = 16/2\\x = 8$

Find an equation of the plane. The plane through the points (0, 9, 9), (9, 0, 9), and (9, 9, 0) Incorrect: Your answer is incorr

Andrei [34K]

Answer:

The equation of the plane is represented by $\frac{1}{18}\cdot x + \frac{1}{18}\cdot y + \frac{1}{18}\cdot z = 1$ .

Step-by-step explanation:

Algebraically speaking, a plane can be represented by following vectorial product:

$(a,b, c)\,\bullet\,(x,y,z) = 1$ (1)

Where:

$a$ , $b$ , $c$ - Plane coeffcients.

$x$ , $y$ , $z$ - Coordinates.

We need three distinct points to determine all coefficients. If we know that $(x_{1},y_{1},z_{1}) = (0,9,9)$ , $(x_{2},y_{2}, z_{2}) = (9,0,9)$ and $(x_{3},y_{3},z_{3}) = (9,9,0)$ , the system of equations to be solved is:

$9\cdot b + 9\cdot c = 1$ (1)

$9\cdot a + 9\cdot c = 1$ (2)

$9\cdot a + 9\cdot b = 1$ (3)

The solution of this system is $a = \frac{1}{18}$ , $b = \frac{1}{18}$ , $c = \frac{1}{18}$ .

Hence, the equation of the plane is represented by $\frac{1}{18}\cdot x + \frac{1}{18}\cdot y + \frac{1}{18}\cdot z = 1$ .
