Answer:
Scale factor is the ratio of any two corresponding lengths in two similar geometric figures
Length of sign ×scale factor=length of flyer
scale factor = 1:3
Step-by-step explanation:
when you have two figures which are geometric similar, the scale factor is the ratio of their corresponding side's lengths.
To find scale factor you identify the sides that are similar in the figures then get the ratio of their lengths.
Given the dimensions of sign as ;
width= 2 feet--------change to inches by multiplying by 12 (1 foot=12 inches)
width=2*12=24 inches
length= 2feet 6 inches
length= 24+6 =30 inches
Hence the sign has dimensions
width=24 in
length=30 in
Flyers dimensions
width=8 in
length=10 in
Finding Scale factor
length of sign ×scale factor=length of flyer
30×scale factor=10
scale factor=10/30 =1/3 or 1:3

Answer:
y = 5x - 7
Step-by-step explanation:
We can make an equation for the perpendicular line by swapping the x- and y-coefficients, negating one of them. Then we can use that form with the given point to see what the constant is.
10x -2y = ...
Removing a common factor of 2 gives ...
5x -y = 5(2) -(3) = 7 . . . . using (x, y) = (2, 3), we can find the constant
Solving for y, we get ...
5x -7 = y . . . add y-7
y = 5x -7 . . . write in the desired form
Answer:
The simplified form of expression<u> </u>(-2 - 8x) + (-4x - 10) is
-12(x + 1)
Step-by-step explanation:
It is given an expression (-2 - 8x) + (-4x - 10)
<u>To find the simplified expression of (-2 - 8x) + (-4x - 10)</u>
Let expression is given by
(-2 - 8x) + (-4x - 10) = -2 - 8x -4x -10
= -2 -10 -4x -8x
= -12 -12x
-12(x + 1) (since -12 is common in both terms)
Therefore simplified form is -12(x + 1)
