Answer:
y=8(0.5)^x
Step-by-step explanation:
We can find the value of b, which is the rate. The rate is 0.5 because the y value is consistently going down by 2. A is the first value, which is 8. y=8(0.5)^x
 
        
             
        
        
        
Answer:
(x+7) is not a factor
Step-by-step explanation:
we know that
If (x+7) is a factor of f(x)
then
For 
Verify
we have

Answer:
   x = 21
Step-by-step explanation:
The parallel lines divide the segments proportionally.
   x/27 = 28/36
   x = 27(28/36) . . . . multiply by 27 (in your head: (3·9)(4·7)/(4·9) = 3·7)
   x = 21
