elena-s [515]

Answer:

a^n=-9+(n-1).5

Step-by-step explanation:

Arithmetic sequence=a+(n-1)d

a=-9

n=?

d=+5

Arithmetic sequence=-9+(n-1)5

=-9+5n-5

Collect like terms

-9-5+5n

-14+5n

So the final answer is

an=-9+(n-1).5

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.

A battery with
horrorfan [7]
Y = 5x + 20

Start at (0, 20).
Then plot a point at (1, 25).

The line should be going through points (2, 30), (3, 35), (4, 40), (5, 45), etc.

For every time the x number goes up, the y number goes up 5 times for the 5%.

What number should come next ?
babymother [125]
<h2>Answer: <u>The number that comes next is 52 </u></h2>

Step-by-step explanation:

2 + (1^2 - 1 ) = 2

2 +( 2^2 - 1 ) = 5

5 + ( 3^2 - 1) = 28

28 + (5^2 - 1) = 52

Thus the next number would be 52

Hope this helps :D
