Answer:
The x-axis should be the units and the y-axis should be the prices.
Step-by-step explanation:
IF you guys have time, this is my explanation:
In a graph, we always think of "rise over run" or "y over x." Another way to write this is "y PER x." For example, 90 percent is "90 per 100," which can also be written as, "90 OVER 100." So, do we have price per unit or unit per price?
The answer would be, "unit per price." This is because the question asks to compare the unit prices, not the price units. Think unit price = unit PER price. Price unit = price PER unit. So the question asks, "For every unit, what will the price be?"
Therefore, units is x and prices are y because we are trying to compare price per unit, which we now know is y PER x.
Answer:
No it doesnt
Step-by-step explanation:
It doesnt, because the x values or domain repeat here. It would be a functionif the x didnt repeat. Y can repeat but x cant. Hope it helps. Feel free to ask questions. God bless you
I got the answer to be 0.9. To get the mean, you add up all the data and then divide it by the number of numbers in you data, so I did 0.5+0.7+1.0+1.7+0.6+1.0=0.8 and then divided by 7, giving me 0.9.
Answer:
A. (-1, -4)
Step-by-step explanation:
The vertex can be found by converting the equation from standard form to vertex form.
<h3>Vertex</h3>
Considering the x-terms, we have ...
y = (x^2 +2x) -3
where the coefficient of x is 2. Adding (and subtracting) the square of half that, we get ...
y = (x^2 +2x +(2/2)^2) -3 -(2/2)^2
y = (x +1)^2 -4
Compare this to the vertex form equation ...
y = a(x -h)^2 +k
which has vertex (h, k).
We see that h=-1 and k=-4. The vertex is (h, k) = (-1, -4).
On the attached graph, the vertex is the turning point, the minimum.
