Pregunta Diagnostica: Un objeto de 10 kg de masa viaja a 30 m/s, y se mueve en oposición a otro cuya masa es de 5 kg y viaja a 50 m/s. Si el hoque es perfectamente elastico, las velocidades de los cuerpos después del choque son de 50 y 30 m/s 56,67 y 36.67 m/s 43.33 y 23:33 m/s 56.67 y 23.33 m/s​

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-by-step explanation:
