The GreatestCommonFactor is 20.........
First, it is to be noted that the variable being used in this item is p. We get the value of 1/3 of p by multiplying 1/3 to p giving us p/3. Then, the word less means to subtract from p/3 the given value. Therefore, the final expression for this item is,
p/3 - 2

Answer:
The value of a = 3
Step-by-step explanation:
Given the function

From the attached graph, it is clear that
at x = 0,

∵ 

Thus
When x = 0, the y-intercept will be:

From the attached figure, it is clear that
at x = 0, the value of y = 3
so
putting y = 3 in the equation

3 = a ∵ 
Therefore, the value of a = 3
