Answer:
Step-by-step explanation:
An equation in the vertex form is written as
Where the point (h, k) is the vertex of the equation.
For an equation in the form 
the x coordinate of the vertex is defined as
In this case we have the equation 
.
Where
Then the x coordinate of the vertex is:
The y coordinate of the vertex is replacing the value of 
in the function
Then the vertex is:
Therefore The encuacion excrita in the form of vertice is:
To find the coefficient a we substitute a point that belongs to the function
The point (0, -1) belongs to the function. Thus.
<em>Then the written function in the form of vertice is</em>
To solve this problem you must apply the proccedure shown below:
1. You have that Darren can get to work in
and <span>with the traffic and lights, he can average </span>
<span>.Therefore, you must apply the formula for calculate the distance, which is:
</span>
<span>
Where </span>
<span> is the speed and </span>
<span> is the time.
2. The time in hours is:
</span>
<span>
3. Substituying values, you have:
</span>
<span>
The answer is:</span>
Ok, let’s take it step by step.
In order to write an equation in slope intercept form, solve for y.
3x+4y=12
First, subtract 3x from both sides.
4y=-3x+12
Now, divide both sides by 4.
y=-3/4x+3.
So, 3x+4y=12 written in slope intercept form is y=-3/4x+3.
