Problema de capacidades Una empresa aceitera ha envasado 3000 litros de aceite en 1200 botellas de dos y de cinco litros. ¿Cuánt
mariarad [96]

Answer:

Hay 200 botellas de 5 litros y 1000 botellas de 2 litros.

Step-by-step explanation:

Un sistema de ecuaciones lineales es un conjunto de dos o más ecuaciones de primer grado, en el cual se relacionan dos o más incógnitas.

Resolver un sistema de ecuaciones consiste en encontrar el valor de cada incógnita para que se cumplan todas las ecuaciones del sistema.

En este caso, las variables a calcular son:

  • x= cantidad de botellas de 2 litros.
  • y= cantidad de botellas de 5 litros.

Una empresa aceitera ha envasado 3000 litros de aceite en 1200 botellas de dos y de cinco litros. Entonces es posible plantear el siguiente sistema de ecuaciones:

\left \{ {{2*x+5*y=3000} \atop {x+y=1200}} \right.

Existen varios métodos para resolver un sistema de ecuaciones. Resolviendo por el método de sustitución, que consiste en despejar o aislar una de las incógnitas y sustituir su expresión en la otra ecuación, despejas x de la segunda ecuación:

x= 1200 - y

Sustituyendo la expresión en la primer ecuación:

2*(1200 - y) + 5*y=3000

Resolviendo se obtiene:

2*1200 - 2*y + 5*y= 3000

2400 +3*y= 3000

3*y= 3000 - 2400

3*y= 600

y= 600÷3

y= 200

Reemplazando en la expresión x= 1200 - y:

x= 1200 - y

x=1200 -200

x= 1000

<u><em>Hay 200 botellas de 5 litros y 1000 botellas de 2 litros.</em></u>

Solve the equation using the Zero-Product property<br><br> (2x-8)(7x+5)=0
Alekssandra [29.7K]
(2x-8)(7x+5)=0

2x-8=0
Divide both sides by 2
X-4=0
Add 4 to both sides
X=4

7x+5=0
Subtract 5 from both sides
7x=-5
Divide both sides by 7
X=-5/7

X=4, x=-5/7

Hope this helps :)

Question is shown in picture
konstantin123 [22]

To solve either part of this problem, you first need to find the slope of the line.  You can do this using the slope formula \frac{y_{2}- y_{1} }{x_{2}- x_{1} }.  In this problem, y2=2, y1=7, x2=1, and x1=-4.  Plug those values into the slope formula to find the slope.

\frac{2-7}{1--4}= \frac{-5}{5} =-1

The slope of the line is -1.


For the first part of the question, you need to create the point-slope equation.  Point-slope equations follow the model (y-y)=m(x-x), where m is the slope and x and y are coordinates.

We know the slope is -1.  To find the coordinates, take x and y from one of the ordered pairs (it doesn't matter which, but you cannot take x from the first one and y from the second).  We'll use the first one: (-4, 7).

The point-slope equation is (y-7)=-1(x+4).

The x is "plus" because the coordinate is negative, and subtracting a negative number is the same as addition.


To find the slope-intercept form, you can use the point-slope equation and solve for y.  Start by distributing the -1.  The equation becomes:

y-7=-x-4

Next, add 7 to both sides.  It becomes:

y=-x+3

Slope-intercept form follows the model, y=mx+b, where m is the slope and b is the intercept.  y=-x+3 matches this model because -1 is the slope and 3 is the intercept.

The slope-intercept equation is y=-x+3.


Hope this helps and makes sense!
