Answer:

Step-by-step explanation:
we are given
y varies directly as x
so, we can write equation as

where 
k is constant of proportionality
We have 
at x=-1 , y=6
so, we can use it to find k 

so, we get 

now, we can plug it back

now, we can plug x=5
and we get 


 
        
             
        
        
        
Answer:
Step-by-step explanation:
y+ 6= 5(x-4) 
y + 6= 5x-20 
    -6 .      -6
  ----------------
y= 5x-26
 
        
             
        
        
        
The width is the first numbers.
Width = 225 mm
Aspect ratio is the second number.
Aspect ratio is 45
Aspect ratio is width / height.
You have the ratio and width so you can calculate the height:
Multiply the width by the ratio:
Height = 225 x 0.45 = 101.25 mm
101.25/25.4 = 3.98 inches
The rim
Diameter is the last number
Rim diameter = 17 inches
So the overall height would be approximately 17 + 3.98 + 3.98 = 24.96 inches
Round the answers as needed.
