Answer:
with the video game cost of x = $6
This agrees with the last option in the list of possible answers
Step-by-step explanation:
Recall that the maximum of a parabola resides at its vertex. So let's find the x and y position of that vertex, by using first the fact that the x value of the vertex of a parabola of general form:
is given by:
In our case, the quadratic expression that generates the parabola is:
then the x-position of its vertex is:
This is the price of the video game that produces the maximum profit (x = $6). Now let's find the y-position of the vertex using the actual equation for this value of x:
This value is the highest weekly profit (y = $246).
Now, recall that we can write the equation of the parabola in what is called "vertex form" using the actual values of the vertex position :
Therefore the answer is:
with the video game cost of x = $6
Answer:
The solution is B) (2, ).
Step-by-step explanation:
This system of equations can be solved by elimination, where we add the two equations together to eliminate one of the variables and solve for the remaining variable:
x + 2y = 3
<u>3x - 2y = 5</u>
4x = 8 or x = 2
To solve for 'y', plug in the value of x: 2 + 2y = 3 or 2y = 1 or y =
Putting the values into the point (x, y) = (2, )
