(5x+3) is the width, its factors form is (5x+3)(3x-5)
        
             
        
        
        
Answer:
a) yx=63
b) y=3
Step-by-step explanation:
a)
yx=k (inverse formula)
7(9)=k
63=k
b)
y(21)=63
y=63/21
y=3
 
        
             
        
        
        
Answer:

Step-by-step explanation:
See attachment for complete question.
From the attachment:


Dilation:

Required
Determine R'
First, subtract the coordinates of P from R. This means that R is measured from P.



Next, apply dilation factor 0.5




Lastly, measure R' from the origin by adding the coordinates of P to R'
