the answer to that question is 31.80
THe answe is 6x squared on the number line
Answer: y = 7- 5x
Step-by Step Explanation: The variable x is multiplied by a larger value here; it's multiplied by 5. So I should expect that my y-values will grow fairly quickly. This means that I should expect a fairly "tall" graph.
First I'll do the T-chart.
T-chart
This equation is an example of a situation in which you will probably want to be particular about the x-values you pick. Because the x is multiplied by a relatively large value, the y-values grow quickly. For instance, you probably wouldn't want to use x = 10 or x = –7 as inputs. You could pick larger x-values if you wished, but your graph would very quickly get awfully tall.
I can see, from my T-chart, that my y-values are getting pretty big on either end (that is, in the positive numbers above the horizontal axis, and in the negative numbers below). I don't want to waste time computing points that will only serve to make my graph ridiculously large, so I'll quit with what I've got so far. But I'm glad I plotted more than just two points, because lines that start edging close to vertical can easily go wrong, if I'm not neat in my work.
Here's my graph:
y = 7 - 5x
14.85 divided by 36 is all you needed to do,an that is .41

Answer:
P = 250 +50t
Step-by-step explanation:
We are given two pairs of time and price:
(t, P) = (0, 250) and (5, 500)
We can put these into the 2-point form of the equation for a line:
y = (y2 -y1)/(x2 -x1)(x -x1) +y1
P = (500 -250)/(5 -0)(t -0) +250
P = 250/5t +250
P = 50t +250 . . . . Madelyin's cost equation
