Answer:

Step-by-step explanation:

ABC is transformed into DEF.

We find from the pictures given that

when ABC is transformed in to DEF, there are three steps of transformations involved

I transformation is Triangle ABC is rotated by 90 degrees about Vertex A

Then we would get a right triangle with AC horizontal on top and AB vertically down with vertex A same as (-5,-4)

Next is simple transformation of shifting A to D i.e. vertex (-5,-4) to (2,2)

For this, first shifting of 7 units to the right is done to make A as (2,-4)

Now next is vertically up by 6 units so that A becomes (2,2)

Thus we have a series of 3 transformations

i) rotation about A 90 degrees

ii) Shifting to right by 7 units

iii) shifting up by 6 units

Step-by-step explanation:

A) 63 x (1 + 0.50) = 94.5

B) 94.50 = P(63)

94.50 (1/63)=P(63)(1/63)

1. La asistencia a un juego de béisbol profesional fue de 4500 personas y el dinero
Elena-2011 [213]

Resolviendo un sistema de ecuaciones veremos que se vendieron 900 boletos de $15 y 3600 boletos de $10.

<h3> ¿Cuántos boletos de cada tipo se vendieron?</h3>

Primero definamos las variables:

  • x = número de bolteos de $10 vendidos.
  • y = número de bolteos de $15 vendidos.

Sabemos que se vendieron 4500 boletos, entonces:

x + y = 4500

Y se recaudo un total de $49,500, entonces:

x*$10 + y*$15 = $49,500

Entonces tenemos un sistema de ecuaciones:

Para resolver esto, primero debemos aislar una de las variables en la primer ecuación, voy a aislar x:

x = 4500 - y

Ahora reemplazamos esto en la otra ecuación:

(4,500 - y)*$10 + y*$15 = $49,500

Ahora debemos resolver estoy para y.

$45,000 - y*$10 + y*$15 = $49,500

y*$5 = $49,500 - $45,000 = $4,500

y = ( $4,500)/$5 = 900

Entonces:

x = 4500 - 900 = 3600

Se vendieron 900 boletos de $15 y 3600 boletos de $10.

The length of a rectangular garden is 2 feet more than twice it's width. If the area is 40 square feet, how much fencing would b
Westkost [7]

Answer:

w =4 ft and l =10 ft

Step-by-step explanation:

Let w = width

l = 2w+2

A = l*w

A = (2w+2)(w)

 40  = (2w+2) w

Distribute

40 = 2w^2 +2w

Subtract 40

0 = 2w^2 +2w - 40

Dividing each side by 2

0 = w^2 +w -20

Factor

0 = (w+5) (w-4)

Using the zero product property

w+5 =0     w-4=0

w= -5  w=4

Since we cant have a negative length

w=4

l = 2w+2 = 2(4)+2 = 8+2 =10
