Answer:
6.95
Step-by-step explanation:
Check the picture below, that's a parabolic graph of a quadratic equation with a negative leading coeffficient, like this one, the one in the graph is just for initial velocity, but, the highest point is at the vertex for any of these parabolas.
and this one is not exception, so where's the vertex? what's A or the y-coordinate when the vertex is reached?, well, let's check.

so, that's the vertex, and when the width is that much, the Area reaches a maximum of that much.
Answer:
12x-11
Step-by-step explanation:
There is no known solution, but this can be simplified. Add up all of the coefficients(# connected by the variable). Since after 7x is a - , the x following has to be negative. After adding the coefficients, you should have below, 12x. Then, you add up all of your constants.(# w/ no variable). Adding negative and positive, you should get below, -11. Finally, you should of simplified your equation to 12x-11.
Equation:
7x- (x-4)= 6x -7
<u>7x- (x</u>-4)= <u>6x</u> -7
12x
7x- (x-<u>4</u>)= 6x <u>-7</u>
-11
12x-11
Answer:
Domain: {-2, 0, 1, 3}
General Formulas and Concepts:
<u>Algebra I</u>
- Domain is the set of x-values that can be inputted into function f(x)
Step-by-step explanation:
We are given a set of coordinates:
{(-2, 4), (1, 3), (0, -4), (3, 2)}
We can separate the <em>x</em> and <em>y</em> values:
x: {-2, 1, ,0, 3}
y: {4, 3, -4, 2}
We know that domain is all x-values. Rearrange into number line form:
x: {-2, 0, 1, 3}
