Answer:
The vertex of this equation is (2, -7)
Step-by-step explanation:
In order to find the vertex of this equation we start with the base form of the vertex form.
y = a(x - h) + k
With this equation (h, k) is the vertex. You can see that 2 lines up with h and -7 lines up with k. This shows that (2, -7) is the vertex.

EXPLANATION</h3>
To work this out, you need to<em> times 1.2 by 7</em>, to get the answer of <u>8.4 litres</u>.
Hope this helps!
It's probably A because the fact that it is multiplied by 4 wouldn't change the number of zeros, and 10 to the 3rd power would be 1000 (if you include the X4 in this example it would be 4000).
