Answer:
1x
Step-by-step explanation:
12x-9= 3x.
1/3 of 3 is 1.
So therefore the answer is 1x.
1. vertex is -4 because:
x^2-8x-20,
a=1, b=-8 , c=-20
use vertex form! -b/2a = -8/2(1) = -8/2 = -4.
2. axis of symmatry is the x which is also -4. The same steps go for the second one.
3. y intercept, I think the answer is -20. Im not sure for this one.
