Usando conceptos de funciones lineales, se encuentra que hizo 5 cortes.

----------------

Una funcion lineale tiene el seguiente formato:

y(x) = ax + b

En que:

  • a eres lá inclinacion, o sea, lo que es pago por cada corte.
  • b eres el intercepto, o sea, lo pagamiento fixo por día.

----------------

  • Pagan $50 por corte realizado, o sea, a = 50.
  • $25 fixo al día, o sea, b = 25

Entonces, la funcion de su recibimiento y, como funcion de su numero de cortes x, es da por:

y(x) = 25 + 50x

----------------

  • Recibió $275, o sea, y(x) = 275

Entonces, el numero de cortes es:

y(x) = 25 + 50x

25 + 50x = 275

50x = 250

x = \frac{250}{50}

x = 5

Realizó 5 cortes.

Queremos encontrar y resolver una ecuación lineal que representa el problema dado.

Veremos que el miércoles Rocío realizó 5 cortes.

La información que se nos da es:

Rocío recive $50 por corte.

Adicionalmente, recibe $25 por día (esto se paga una sola vez)

Entonces si Rocío realiza x cortes, la cantidad de dinero que recibirá es:

C(x) = $25 + $50*x

Ahora sabemos que un dado día ella recibe $275, queremos ver cuantos cortes realizo ese día, entonces debemos resolver la ecuación lineal:

C(x) = $275 = $25 + $50*x

         $275 - $25 = $50*x

         $250 = $50*x

         $250/$50 = x = 5

Así podemos concluir que Rocío realizó 5 cortes.

Answer:

<h2>          \bold{a_n=-7n+39}</h2>

Step-by-step explanation:

25 - 32 = -7  and 18 - 25 = -7

It means an arithmetic sequence with common difference d = -7

a_n = a_1+d(n-1)\\\\a_1=32\\d=-7\\\\a_n=32+(-7)(n-1)\\\\a_n = 32-7n+7\\\\\underline{a_n=-7n+39}
