Pentagon PQRST Is Drawn On A Coordinate Plane Below. What Rule Best Represents A Dilation To Create Pentagon

Answers

Answer 1

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]

Jimmy takes 12 minutes to run 6 times around a 600 meter track. Assuming he runs at a constant speed, how long does he take to run 1 kilometer?

Answers

Answer:

10/3 minutes

Step-by-step explanation:

12 minutes to run 6 times is the same as 2 minutes to run once (ratios)

so it takes 2 minutes to run once around a 600 m track

so 2 minutes/600m = x minutes/1000m

x = 2/600 * 1000 = 20/6 = 10/3

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
