Angelina_Jolie [31]

Answer:

  • Total cost/Costo total: TC=524+6x
  • Slope/pendiente: change in total cost when we produce an additional unit /cambio en el costo total cuando se incrementa la produccion en una unidad.
  • Total cost if 345 tables are made/costo total por elaborar 345 mesas: TC=524+6\times{345}=2594.

Step-by-step explanation:

  • Total cost/Costo total: 524+6x. Total amount of money spent when producing x amount of tables, equals a fixed amount that must be paid and an extra of $6 for every additional table produced./ Cantidad de dinero gastado cuando se produce una cantidad x de mesas, es equivalente a $524 de costos fijos mas $6 adicionales por cada mesa producida.
  • Slope/pendiente: change in total cost when we produce an additional unit. It is the coefficient that is linkes the extra amount of money spent when producing an extra unit of x (tables). /Cambio en el costo total cuando se incrementa la produccion en una unidad. El el coeficiente que vincula el cambio en el costo total con el cambio en las cantidades producidas.
  • Total cost if 345 tables are made/costo total por elaborar 345 mesas: TC=524+6\times{345}=2594. (Is the result of replacing in the equation x=345, which means to evaluate the total costo when we produce 345 tables/Es el resultado de remplazar en la ecuacion x=345, lo que resulta en saber el costo total de producir 345 mesas).

Rina8888 [55]

Answer:

m+6n

Step-by-step explanation:

Let number of men who attended last year=m

Let number of women who attended last year=n

This year, we expect Six times the amount of women attendance last year =6 X n = 6n

The same number of men, m will be expected this year

Therefore, Number of Expected Attendees

= Number of Men + (Six Times the Number of Women)

=m+6n

We can expect (m+6n) people to be in attendance this year.

Write an equation that is parallel to the line x + 3y = 2 and passes through the point (1, 0).
Nady [450]

Answer:

y = -1/3x + 1/3

Step-by-step explanation:

x+3y=2

3y = 2 - x

y = 2/3 - 1/3x

y = -1/3x +2/3

the slope is -1/3 and the equation that is parallel will have the same slope also

y = mx + b

y = -1/3x + b

0 = -1/3(1) + b

0 = -1/3 + b

1/3 = b

y = -1/3x + 1/3
