Answer:
Step-by-step explanation:
its not right equation
because
5X - 10 ≠ 2X - 4
Answer:
B
Step-by-step explanation:
Using the expansion
tan(x - y) =
, then
tan(x -
)
= 
note that tan( -
) = - tan(
) = - 
= 
=
→ B
Answer:
x - 10, I believe
Step-by-step explanation:
The differences between the x-values and the y-values are
1) 12 & -12 = 0
2) -4 & 0 = 4
3) 0 & 7 = 7
4) 10 & 0 = -10
Since the question asks which must be A factor of p(x) or the y-value, I would advise to look for the answer that helps you receive one of the differences shown above. That said, I would go with <em>x - 10.</em>

Does that help?
