Answer:
Vertex form is

where (h,k) is the vertex
So our vertex form is

It passes through (6,0) so we have

Solve for a.



So our equation is

Answer:
y = 110 and x = -15
Step-by-step explanation:
y = 110 because whenever x = 0 then y is the number in relation with x.
So it would be
y = -15x + 110
I used my calculator.
I'm going to say 180 degrees
Answer:
It would be the transitive property! If you look up "If a = b, and b = c, then a = c" you'd see the transitive property. I hope this helps!
