El costo de producir 10 juegos de video al día es de 350 dólares , mientras que producir 30 juegos del mismo tipo al día cuestan
Dovator [93]

Answer:

El coste de producir un juego de vídeo es de 125 dólares.

Step-by-step explanation:

(This exercise is written in Spanish and is incomplete. Complete statement will be presented below)

El costo de producir 10 juegos de video al día es de 350 dólares , mientras que producir 30 juegos del mismo tipo al día cuestan 850 dólares . Si suponemos un modelo lineal como el descrito anteriormente , determine:

¿Cuál es el costo de producir un juego de vídeo?

(Explanation will be held in Spanish)

El modelo lineal es un polinomio de primer orden de la forma:

y = a\cdot x + b

Donde:

x - Variable independiente (eje x - Cantidad de juegos de vídeo producidos - Adimensional)

y - Variable dependiente (eje y - Coste de producción de juegos de vídeo - Dólares)

a - Pendiente de la función.

b - Intercepto en el eje y.

Dados los dos costes para dos cuotas distintas de producción, se construye el siguiente sistema de ecuaciones lineales:

10\cdot a + b = 350

30 \cdot a + b = 850

Se resuelve el sistema con algo de manipulación algebraica:

(30\cdot a + b) - (10\cdot a + b) = 850 - 350

20 \cdot a = 500

a = 25

Luego:

b = 850 - 30\cdot a

b = 100

La ecuación lineal es:

y = 25\cdot x +100

Finalmente, el coste de producir un juego de vídeo es:

y = 25 \cdot (1) + 100

y = 125

El coste de producir un juego de vídeo es de 125 dólares.

If 2x+8=16, what is the value of x+4?​
True [87]

Answer:

\boxed{ \bold{ \huge{ \boxed{ \sf{8}}}}}

Step-by-step explanation:

<u>First</u><u>,</u><u> </u><u>finding </u><u>the </u><u>value</u><u> </u><u>of</u><u> </u><u>x</u>

\sf{2x + 8 = 16}

Move 8 to right hand side and change it's sign

\dashrightarrow{ \sf{2x = 16 - 8}}

Subtract 8 from 16

\dashrightarrow{ \sf{2x = 8}}

Divide both sides by 2

\dashrightarrow{ \sf{ \frac{2x}{2}  =  \frac{8}{2} }}

Calculate

\dashrightarrow{ \sf{x = 4}}

Value of x is 4

<u>Now</u><u>,</u><u> </u><u>Substituting</u><u> </u><u>/</u><u> </u><u>Replacing </u><u>the</u><u> </u><u>value </u><u>of</u><u> </u><u>x</u><u> </u><u>in</u><u> </u><u>order</u><u> </u><u>to</u><u> </u><u>find</u><u> </u><u>x</u><u>+</u><u>4</u>

<u>\sf{x + 4}</u>

plug the value of x

\dashrightarrow{ \sf{4 + 4}}

Add the numbers : 4 and 4

\dashrightarrow{ \sf{8}}

Hope I helped!

Best regards! :D
