Oh gosh….this is my personal nightmare. i’m sorry i don’t know
Answer:
12/7
Step-by-step explanation:
- Vertex form:
, with (h,k) as the vertex.
For this, we will be using vertex form. Firstly, plug the vertex into the vertex form equation:

Next, we need to solve for a. Plug in (-2,4) into the x and y coordinates to solve for a as such:

Putting our equation together,<u> it's
</u>

- Standard form:

Converting to standard form as such:

<span>2(3z-2)+8=34
6z - 4 + 8 = 34
6z + 4 = 34
6z = 34 -4
6z = 30
z =30/6
z = 5
