14. En la primera ronda de una competencia de ajedrez hay 20 participantes, pero solo 16 pasarán a la segunda ronda. El orden en que los participantes resulten clasificados es muy importante, ya que eso determinará quién será su contrincante en la segunda ronda. Resuelvan las consignas en grupos. ¿De cuántas maneras pueden clasificarse 16 participantes para la segunda ronda de entre los 20 iniciales?

answer: the price of one pound cabbage = $ 0.8

the point (10,8) represents that the cost of 10 pounds cabbage is $ 8

step-by-step explanation:

since, here is a proportional relation between the number of pounds of cabbage (x) and the price in dollars (y).

therefore, we can write,

⇒ y = k x

where k is the constant of proportionality.

now, point (5,4) is in the line.

thus, it will satisfies the above equation of line.

⇒ 4 = 5 k

⇒ k = 0.8

thus, the equation of the line is,

y = 0.8 x

a) for x = 1,

y = 0.8

therefore, the cost of one pound of cabbage is 0.8 dollars.

b) in the below graph (10,8) represents that the cost of 10 pounds of cabbage is 8 dollars.

step- i d k and i d c : )

you: : 0

bye

i use my brain for prombles like this maybe you could try it
