Answer: D.
Step-by-step explanation:
The last statement is false.
Hey there!
The equation for axis of symmetry is ![\frac{-b}{2a}](https://tex.z-dn.net/?f=%5Cfrac%7B-b%7D%7B2a%7D)
The A, B, and C are:
Ax+By+C= f(x)
A=4 B=-8 C=12
So we have:
![\frac{-(-8)}{2(4)}](https://tex.z-dn.net/?f=%5Cfrac%7B-%28-8%29%7D%7B2%284%29%7D)
Two negatives make a positive.
![\frac{8}{8}](https://tex.z-dn.net/?f=%5Cfrac%7B8%7D%7B8%7D)
8/8= 1
x=1 is the correct answer.
I hope this helps!

Answer:
These are both 20 so that means that this is proportional, yes.
Step-by-step explanation:
Hi.
To figure this out we can do something called cross multiplying to find a cross product. If we do this and our two answers are equal then it is indeed a proportion.
Here is how we do this.
![\frac{10}{5}](https://tex.z-dn.net/?f=%5Cfrac%7B10%7D%7B5%7D)
So basically what we are doing is multiplying across in a diagonal direction.
Diagonal meaning like a slash / .
So in this case we would multiply the 4 and the 5 , since they're diagonal from each other.
Do the same for the 2 and the 10.
So we have to multiply :
4 x 5
2 x 10
=
20
These are both 20 so that means that this is proportional, yes.
Hope this helps.
