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,
 units
 units
 units
 units
Now,


A dilation factor of  was performed on PQRS to form P'QʻR'S'.
 was performed on PQRS to form P'QʻR'S'.
Therefore, the correct option is (3).
 
        
             
        
        
        
Answer:
13
Step-by-step explanation:
Let the number be x. 
ATQ x+22=455/x. x^2+22x=455. x=-35 or 13. Since x is positive, x=13
 
        
             
        
        
        
slope intercept form is: y = mx + b
m = slope
b = y-intercept
In the equation y = 1/4x + 8
m = 1/4 = slope
b = 8 = y-intercept
