Answer:
The vertex of the function is 
Step-by-step explanation:
Vertex of a quadratic function:
Suppose we have a quadratic function in the following format:

It's vertex is the point 
In which


Where

If a<0, the vertex is a maximum point, that is, the maximum value happens at
, and it's value is
.
f(x) = x² - X + 2.
Quadratic equation with 
So



The vertex of the function is 
Answer: 9
Step-by-step explanation:
Given
The function is 
To make it a perfect square, compare it with 
Here,

So, c must be square of b i.e. 9

Therefore, value of c is 9.
"one tenth" as a decimal is 0.1 .
You have to leave Y by itself in one side. To do that, you need to subtract 2x from both sides. You're now left with -3y = 8-2x. Last step is that you divide 3y, 8, and -2 by -3.
Good luck :)
