Y=-4x + 2 y = -x - 1

USPshnik [31]3 years ago

Hey there! I'm happy to help!

We have two values for y in terms of x. We can now create an equation to solve for what x is.

-4x+2=-x-1

We add x to both sides

-3x+2=-1

We subtract 2 from both sides.

-3x=-3

We divide both sides by -3.

x=1

Now, we can plug our x into one of the original equations and then solve for y!

y= -4+2

y=-2

We can also test this with the other.

y= -1-1

y=-2

Therefore, our solution is (1, -2), or x=1 and y=-2.

I hope that this helps!

El volumen <em>remanente</em> entre la esfera y el cubo es igual a 30.4897 centímetros cúbicos.

<h3>¿Cuál es el volumen remanente entre una caja cúbica vacía y una pelota?</h3>

En esta pregunta debemos encontrar el volumen <em>remanente</em> entre el espacio de una caja <em>cúbica</em> y una esfera introducida en el elemento anterior. El volumen <em>remanente</em> es igual a sustraer el volumen de la pelota del volumen de la caja.

Primero, se calcula los volúmenes del cubo y la esfera mediante las ecuaciones geométricas correspondientes:

Cubo

V = l³

V = (4 cm)³

V = 64 cm³

Esfera

V' = (4π / 3) · R³

V' = (4π / 3) · (2 cm)³

V' ≈ 33.5103 cm³

Segundo, determinamos la diferencia de volumen entre los dos elementos:

V'' = V - V'

V'' = 64 cm³ - 33.5103 cm³

V'' = 30.4897 cm³

El volumen <em>remanente</em> entre la esfera y el cubo es igual a 30.4897 centímetros cúbicos.

In a group of 50 people 28% of them has flue shots done. What is the probability to choose from this group 15 people that didn't
aliina [53]

Answer:

0.0025 = 0.25%

Step-by-step explanation:

First we need to find how many people don't have flue shots.

28% of 50 is equal to 0.28 * 50 = 14 people.

If 14 people have flue shots, we have 50 - 14 = 36 people that don't have flue shots.

Now, to solve this problem, the probability will be the cases where  we have a group of people that don't have flue shots (that is, a combination of 36 choose 15) over the total cases (combination of 50 choose 15):

C(36,15) / C(50,15) = (36!/15!*21!) / (50!/15!*35!) = 0.0025 = 0.25%

Write a set of ordered pairs that is represented by the arrow diagram 49,13 69,32 18,22 78,57 28,57 the set of order pair is? 
Komok [63]

Answer:

The mapping can also be represented as the set of ordered pairs: (4, 9) (5, 10) (6, 11) (7, 12). The ordered pair preserves the directional property of the relation. It is consistent with the order of points plotted on a Cartesian Plane represented by (",$). In the Arrow Diagram that follows.
