Answer:
a = -1.
Step-by-step explanation:
y = ax^2 - 4x + 3
Convert to vertex form:-
= a(x^2 - 4/a) + 3
= a [ (x - 2/a)^2 - 4/a^2 ] + 3
From this we see that the line of symmetry is y = 2/a so
2/a = -2
-2a = 2
a = -1.

Answer:
200 Miles
Step-by-step explanation:
If two polygons are similar, then the ratio of a side-length of one of them
to the length of the corresponding side of the other one is the same number
for every pair of sides. All you need to do is find one pair of corresponding
sides, then find the ratio of their lengths, and there's your scale factor.
