The rectangle on the right is a scaled copy of the rectangle on the left. Identify the
scale factor. Express your answer as a whole number or fraction in simplest form.
Answers
Answer:
Scale factor = [tex]\frac{1}{3}[/tex]
Step-by-step explanation:
Given question is incomplete; find the question in the attachment.
Scale factor = [tex]\frac{\text{Dimension of image}}{\text{Corresponding dimension of preimage}}[/tex]
Scale factor = [tex]\frac{\text{Dimension of image rectangle B}}{\text{Corresponding dimension of preimage rectangle A}}[/tex]
From the figure attached,
Length of rectangle B = [tex]\frac{20}{3}[/tex]
Length of rectangle A = 20
Scale factor = [tex]\frac{\frac{10}{3}}{10}[/tex]
= [tex]\frac{\frac{10}{3}}{10}[/tex]
= [tex]\frac{1}{3}[/tex]
Therefore, image rectangle A is dilated with by a scale factor of [tex]\frac{1}{3}[/tex].

Answers
Answer:
The graph of the line x = -2 is also attached below.
Step-by-step explanation:
Given the line
x=-5
x=-5 represents the vertical. We know that the slope of a vertical line is undefined. Thus, the slope of x=-5 is undefined.
Since parallel lines have the same slopes, it means the line which is supposed to be the parallel line to the given line and passing through p(-2, 6) must also be in the form (x = a).
As the line passes through (-2, 6). As the line is vertical, meaning no matter what the value of y is, the x-value remains the same.
Thus, the equation of the line would be x = -2
The graph of the line x = -2 is also attached below.

A rectangular field has a length of x metres.
The width of the field is (2x-5) metres.
Show that the perimeter of the field is (6x-10) metres.
Answers
The perimeter of a shape is the length of all the sides added together. In this problem, the length of the rectangle is x and the width is (2x-5). With the information given, we want to show that it equals or is equivalent to (6x-10), which is supposed to represent the perimeter of the rectangle.
Before I write my equation I what to make sure you understand that there are of course two side lengths of this rectangle and two widths. That being said, the equation would look like this:
2x + 2(2x-5) = 6x-10
(both side lengths) + (both widths) = perimeter
I'll show you how you can simplify this equation to show that the perimeter of the field is 6x-10 :
2x + 2(2x-5) = 6x-10
(first step would be to distribute the 2 into 2x-5)
2x + 4x-10 = 6x-10
(add the x's on the left side to simplify)
6x-10 = 6x-10
Well well, what do we have here :). We ended up with the same expression on each side of the equal sign. We totally know that they're equivalent, in fact they're the same.
(I honestly really hope this helps. I confused myself a little thinking a lot about this problem. Please let me know if you run into any issues with my answer. I'm pretty sure I'm accurate on the work I showed. I also wasn't able to view your PDF sadly :( )

you get y=0 -4= -4
so x=0 y= -4
look at each graph
then substitute y=0
into y=abs(x) -4
you get 0= abs(x) -4
4=abs(x)
x=4 or x=-4
look at each graph
so you will find it`s graph 2
