Answer: The answer is 2.
All they're doing is multiplying by 2.
 
        
             
        
        
        
F(x) = 4x - 1. You can get this by using the slope formula and then point-slope form. 
1. The slope of f(x) is twice as steep as that of g(x).
2. The y intercept of g(x) is much greater than that of f(x) because 8>-1
        
             
        
        
        
In case A, as the error would be a difference of 1, the assumption could be mantained, but in case B the difference will be bigger, showing that the ratio is not 3:1 but 4:1.
<h3><u>Ratios</u></h3>
Given that a preliminary study was carried out to test the hypothesis that the ratio of white to dark herons on the island was 3:1, but A) a small census found 16 white morphs and 4 dark, to determine if the assumption of a 3 :1 ratio could be rejected, and B) to determine the same question if the census were larger with 160 white morphs and 40 dark, the following calculations must be made:
A) 
- 3 + 1 = 4
- 16 + 4 = 20
- 4 = 20
- 3 = X
- 60 / 4 = X
- 15 = X
- Therefore, as the error would be a difference of 1, the assumption could be mantained. 
B) 
- 3 + 1 = 4
- 160 + 40 = 200
- 150 = 3:1
- In this case, the difference will be bigger, showing that the ratio is not 3:1 but 4:1.

Answer:
A
Step-by-step explanation:
The easiest way to simplify the expression below is using a property: if we take random non-0 number  to the 0 power, we finally get 1, so 
 
        
             
        
        
        
The formula of a function is the rise over run. 
The slope would be 2/5. 
Hope this helps!
