Calcule la ecuación general de la recta que pasa por la intersección de la recta:
adell [148]

La ecuación general de la recta es x + 3 · y = - 15.

<h3>¿Cómo determinar la ecuación de una recta?</h3>

Según la geometría, una recta es generada por la existencia de dos puntos distintos y en este problema debemos hallar una ecuación de la recta que pasa por la intersección de las dos rectas y otro punto. Primero, determinamos la solución del sistema de ecuaciones lineales para conocer la localización del primer punto:

7 · x - 15 · y = 39                 (1)

5 · x + y = - 19                     (2)

The solución del sistema de ecuaciones lineales is (x, y) = (- 3, - 4).

Segundo, determinamos la pendiente de la recta mediante la fórmula de la recta secante:

m = [- 6 - (- 4)] / [3 - (- 3)]

m = - 1 / 3

Tercero, determinamos el intercepto a partir de la ecuación de la recta:

b = y - m · x

b = - 6 - (- 1 / 3) · 3

b = - 6 + 1

b = - 5

Finalmente, determinamos la ecuación de la recta en su forma general:

y = (- 1 / 3) · x - 5

(1 / 3) · x + y = - 5

x + 3 · y = - 15

La ecuación general de la recta es x + 3 · y = - 15.

P and Q are points on the line 3y - 4x = 12
Lorico [155]

Answer:

Step-by-step explanation:

Since the coordinates of P are (0, 1), this makes P the y-intercept of that line. The y-intercept exists where x = 0. And in the coordinate (0, 1), x does in fact equal 0.

Since the one coordinate given in Q is (?, 0), this means that Q is the x-intercept of the line. The x-intercept exists where y = 0. And in the coordinate (?, 0), y does in fact equal 0. So in order to solve for the x coordinate of Q, we plug in a 0 for y and solve for x:

3(0) - 4x = 12 and

-4x = 12 so

x = -3

Create an equivalent expression for 1.3 cubed over 1.2 raised to the fourth power all raised to the power of negative six. 1.2 r
Oxana [17]

Based on the given parameters, the equivalent expression of [(1.3^3)/(1.2^4)]^-6 is (1.2^[24])/(1.3^[18])

<h3>How to determine the equivalent expression?</h3>

The expression is given as:

[(1.3^3)/(1.2^4)]^-6

Apply the power law of indices to the above expression

[(1.2^4)/(1.3^3)]^6

Next, we expand the exponents using the power law of indices

(1.2^[4 * 6])/(1.3^[3 * 6])

Evaluate the products

(1.2^[24])/(1.3^[18])

Hence, the equivalent expression of [(1.3^3)/(1.2^4)]^-6 is (1.2^[24])/(1.3^[18]) based on the given parameters
