Pentagon PQRST is drawn on a coordinate plane below. what rule best represents a dilation to create pentagon PQRST with a scale factor of 1/2 and with the origin as the center of dilation?

Answers

Answer: [tex](x,y) \to (\dfrac12 x, \dfrac12 y)[/tex]

Step-by-step explanation:

Dilation is a transformation, in which the size of the image gets changed but not shape.

The rule of dilation with scale factor k and wither origin as center of dilation :

(x,y) → (kx, ky)

Here , [tex]k= \dfrac12[/tex] , center of dilation = Origin

Then, the rule best represents a dilation to create pentagon PQRST will be :

[tex](x,y) \to (\dfrac12 x, \dfrac12 y)[/tex]

Step-by-step explanation:

Solve the equations:
1. 9x - 5 = 5x + 7
2. 8x - 2 = x - 16
3. 8x + 5 = 2x + 23
4. 2x + 8 = 5x + 20
5. 5(2x + 6) = 3x - 5

Answers

Answer:

5(x – 4) + 3x – 9x = 6 – (2x + 5) + 8x

step1:-   5x - 20 + 3x - 9x = 6 - 2x - 5 + 8x

step2:- 5x + 3x - 9x - 20 = 8x - 2x + 6 - 5

-x - 20 = 6x + 1

stp 3

-20 = 7x + 1

step 4

-21 = 7x

divide both sides by 7:-

-3 = x

thats the solution   x  = -3

Answer:

1. X=3, 2. X= -2, 3. X=3, 4. X= -4

11x + 6 = 28

Answers

Answer:

X = 2

Step-by-step explanation:

11 x 2 = 22

22 + 6 = 28

Answer is 2
Explanation: you first try to isolate the x
And your only choice is to subtract the 6 so it cancels out on that side and whatever you do to one side you always have to do to another so 28-6 equal 22, 11x=22, now you divide by 11 making it x = 2. Hope this helps if you have any questions ask me

Answers

Answer:

60 percent.

Step-by-step explanation:

Answer:

The answer is 62.5%

Step-by-step explanation:

So basically if u do

%/100= part/whole

1.Use cross product

P/100=40/64

40*100=4000

The p stand for percent

2. Divide the two numbers

64p/64= 4000/64

So what you can do is divide 4000 and 64 and you will get 62.5

P=62.5

Answer:

Length = 11 1/3 ft; Width = 4 2/3 ft

Step-by-step explanation:

First question:

The length is 2 more than twice the width, so

L = 2W + 2

Second question:

2L + 2W = 32

L = 2W + 2

Since the second equation is already solved for L, we can use the substitution method. Replace L of the first equation with 2W + 2, and solve for W.

2L + 2W = 32

2(2W + 2) + 2W = 32

4W + 4 + 2W = 32

6W = 28

W = 28/6 = 14/3 = 4 2/3

L = 2W + 2 = 2(14/3) + 2 = 28/3 + 6/3 = 34/3 = 11 1/3

L = 11 1/3

W = 4 2/3

Answer: Length = 11 1/3 ft; Width = 4 2/3 ft
