So since the vertex falls onto the axis of symmetry, we can just solve for that to get the x-coordinate of both equations. The equation for the axis of symmetry is 
, with b = x coefficient and a = x^2 coefficient. Our equations can be solved as such:
y = 2x^2 − 4x + 12: 
y = 4x^2 + 8x + 3: 
In short, the vertex x-coordinate's of y = 2x^2 − 4x + 12 is 1 while the vertex's x-coordinate of y = 4x^2 + 8x + 3 is -1.
False.
Right triangles do not have to be congruent.

I'm sorry, I don't see the question. Could you please retake the photo in better quality so I could answer it? Thanks!
Answer:
35=0.5x+20
Step-by-step explanation:
y=mx+b
35= money you can spend
0.5= cost of each ride
x=number of rides you ride
20= price to enter
