Step-by-step explanation:

since 2/9 is a bit small

and

since 10/11 is almost whole

Escribe una ecuación de la recta que pasa por el punto (5, –8) con pendiente 5.

Nana76 [90]

Considerando la expresión de una ecuación lineal, la ecuación de la recta que pasa por el punto (5, –8) con pendiente 5 es y= 5x - 33.

<h3>Ecuación lineal</h3>

Una ecuación lineal o línea se puede expresar en la forma y = mx + b

donde

x y son coordenadas de un punto.
m es la pendiente.
b es la ordenada al origen y representa la coordenada del punto donde la línea cruza el eje y.

La ecuación lineal se puede expresar también mediante la ecuación punto-pendiente de la recta, que se plantea si se conoce la pendiente de la recta y cualquiera de sus puntos. Con ello queda determinada la recta, conociendo la pendiente “m” y un punto (x1, y1) dado:

y - y1= m(x -x1)

<h3>Ecuación de la recta en este caso</h3>

En este caso, la recta que pasa por el punto (5, –8) con pendiente 5.

Reemplazando en la ecuación punto-pendiente de la recta:

y - (-8)= 5(x -5)

Resolviendo:

y + 8= 5(x -5)

Aplicando propiedad distributiva:

y + 8= 5x - 5×5

y + 8= 5x - 25

Aislando la variable "y":

y= 5x - 25 - 8

Finalmente, la ecuación de la recta que pasa por el punto (5, –8) con pendiente 5 es y= 5x - 33.

What is the equation of a circle centered at the origin with radius 20?

Colt1911 [192]

We know that
the equation of a circle is
(x-h)²+(y-k)²=r²
where
(h,k)-----> is the center
r--------> is the radius

is the center is the point (0,0) and radius r=20
then
(h,k) is (0,0)

(x-0)²+(y-0)²=20²---------> (x)²+(y)²=400

the answer is
the option D.) x2 + y2 = 400

Copy the figure below onto a separate sheet of paper. Find the image of the figure under reflections in line m and then line t.

son4ous [18]

The image of the pentagon under reflections in line m and then line t is shown below.

<h3>What is a transformation of geometry?</h3>

A spatial transformation is each mapping of feature shapes to itself, and it maintains some spatial correlation between figures.

Reflection does not change the size and shape of the geometry.

The image of the figure under reflections in line m and then line t.

The reflection of the pentagon DEFG will be given in the figure.

More about the transformation of geometry link is given below.

% of 6,000 = 4,500<br> Please help

babymother [125]

Answer:

450

Step-by-step explanation:

Solution for What is 75 percent of 600:

75 percent * 600 =

(75:100)* 600 =

(75* 600):100 =

45000:100 = 450

Now we have: 75 percent of 600 = 450

Question: What is 75 percent of 600?

Percentage solution with steps:

Step 1: Our output value is 600.

Step 2: We represent the unknown value with $x$x.

Step 3: From step 1 above,$600=100\%$600=100%.

Step 4: Similarly, $x=75\%$x=75%.

Step 5: This results in a pair of simple equations:

$600=100\%(1)$600=100%(1).

$x=75\%(2)$x=75%(2).

Step 6: By dividing equation 1 by equation 2 and noting that both the RHS (right hand side) of both

equations have the same unit (%); we have

600

100%

75%

Step 7: Again, the reciprocal of both sides gives

600=

100

Therefore, $75\%$75% of $600$600 is $450$
