Which transformation was performed on PQRS to form P'QʻR'S'? (1 point)
1) A dilation factor of 2
2) A dilation factor of 4
3) A dilation factor of 1/2
4) A dilation factor of 1/4

Answers

Given:

A transformation was performed on PQRS to form P'QʻR'S'.

To find:

The transformation.

Solution:

The given graph shows two similar polygons. It means, dilation was performed.

From the given graph it is clear that,

[tex]PS=2[/tex] units

[tex]P'S'=1[/tex] units

Now,

[tex]\text{Scale factor}=\dfrac{P'S'}{PS}[/tex]

[tex]\text{Scale factor}=\dfrac{1}{2}[/tex]

A dilation factor of [tex]\dfrac{1}{2}[/tex] was performed on PQRS to form P'QʻR'S'.

Therefore, the correct option is (3).

What is the value of x in the system of equations shown below?
5x + 4y = 1
y = 1 - x

Answers

Answer:

x=-3

Step-by-step explanation:

Answer:

x = -3

Step-by-step explanation:

Plug in                

5x + 4(1 - x) = 1    

(y gets replaced by 1 - x)

Multiply                

5x + 4 - 4x = 1

(multiply 4 by whats in the parenthesis)

Combine Constants          

5x - 4x = -3

(constant = numbers without a variable)

(separate constants from variables = numbers with letters)

Combine Variables        

1x = -3

(then you got your answer and you can take the "1" off the x)

Add the x-coordinate of each points to -3 and add the y-coordinates to 6

A (3, 0) -> 3 + -3 = 0   0 + 6 = 6  A' (0, 6)

B (3, -2) -> 3 + -3 = 0   -2 + 6 = 4  B' (0, 4)
