Answer: 48 litros.
Step-by-step explanation:
El recipiente está inicialmente lleno, definamos esta cantidad como X.
Se extrae un tercio, entonces lo que queda en el recipiente son dos tercios de la cantidad inicial, esto es:
(2/3)*X
Luego se extrae (1/4) de esta cantidad, eso quiere decir que queda (3/4) de esta cantidad, entonces lo que queda es:
(3/4)*(2/3)*X = (2/4)*X = (1/2)*X
Luego se agrega un litro, entonces tenemos:
(1/2)*X + 1 L
Sabemos que esta cantidad es igual a 25 L, entonces:
(1/2)*X + 1 L = 25 L
Resolvamos esto para X
(1/2)*X = 25 L - 1 L = 24 L
X = 2*24 L = 48 L
La cantidad que puede contener el contenedor son 48 litros.

Answer:
The equation which best describes the graph of a line that has a slope of - 1/2 and passes through the point (2,-3) will be:
Step-by-step explanation:
The slope-intercept form of the line equation
where
In our case, we are given
The slope m = -1/2
Point (2, -3)
now substituting m = -1/2 and (2, -3) in the slope-intercept form of the line equation to determine the y-intercept
-3 = -1/2(2) + b
-3 = -1 + b
b = -3 + 1
b = -2
now substituting m = -1/2 and b = -2 in the slope-intercept form of the line equation
y = mx + b
y = -1/2x + (-2)
y = -1/2x - 2
Therefore, the equation which best describes the graph of a line that has a slope of - 1/2 and passes through the point (2,-3) will be:
Answer:
y-2=1/3(x+3)
Step-by-step explanation:
m=(y2-y1)/(x2-x1)
m=(4-2)/(3-(-3))
m=2/(3+3)
m=2/6
simplify
m=1/3
y-y1=m(x-x1)
y-2=1/3(x-(-3))
y-2=1/3(x+3)
