¿Cuáles son los procedimientos a ambos lados de la igualdad que se deben realizar para calcular el valor de la incógnita x en la
PilotLPTM [1.2K]

Answer:

Los procedimientos que se deben realizar para calcular la incógnita x en la ecuación 2x+5=7 son:

  1. <u><em>El 5 que está sumando a la izquierda del igual, se pasa a restar a la derecha del igual.</em></u>
  2. <u><em>El 2 que multiplica a x a la izquierda del igual, se pasa a dividir a la derecha del igual.</em></u>

Step-by-step explanation:

Siguiendo los procedimiento descritos en la respuesta, para calcular el valor de la incógnita:

  • 2x + 5 = 7

Seguimos el primer paso: <em>el 5 que está sumando a la izquierda del igual, se pasa a restar a la derecha del igual</em>:

  • 2x = 7 - 5

Seguimos el segundo paso: <em>el 2 que multiplica a x a la izquierda del igual, se pasa a dividir a la derecha del igual:</em>

  • x=\frac{7-5}{2}

Como puedes ver, así se despejaría la incógnita x y solo faltaría operar los datos en la ecuación para obtener la respuesta:

  • x=\frac{2}{2}
  • x=1

<u><em>El resultado que nos daría la incógnita x sería 1</em></u>. Podemos probar el resultado en la ecuación original para comprobar el resultado que obtuvimos:

  • 2x + 5 = 7
  • 2 *(1) + 5 = 7
  • 2 + 5 = 7
  • 7 = 7

Así, identificamos que los procesos realizados fueron correctos.

Find the sum of (1-1/n) + (1-2/n) + (1 - 3/n)....upto n terms
bija089 [108]

Answer:

<em> (n - 1)/2</em>

Step-by-step explanation:

F = (1 - 1/n) + (1 - 2/n) + (1 - 3/n) + ...(1 - n/n)

  = (1 + 1 ... + 1) - (1/n + 2/n + 3/n + ...n/n)

     (there are n terms of 1)

  = n - (1 + 2 + 3 + ... + n)/n

  = n - [n x (n + 1)/2]/n

  = n - [n x (n + 1)]/[2 x n]

  = n - (n+1)/2

  = (2n - n - 1)/2

  = (n - 1)/2

Hope this helps!

State the domain of each function using interval notation<br> pls show ur work!!
Serggg [28]

Answer:

(-∞ , -6] ∪ [6 , +∞)

Step-by-step explanation:

<u>Let D be the domain of f </u>.

D = {x ∈ IR ; where  x² - 36 ≥ 0}

x² - 36 ≥ 0

⇔ x² ≥ 36  

⇔ x² ≥ 6²

⇔ √(x²) ≥ √(6²)

⇔ |x| ≥ 6

⇔ x ∈ (-∞ , -6] ∪ [6 , +∞)
