A price p (in dollars) and demand x for a product are related by

1 answer:

7 0

<span>Plugging in p = 10 to solve for x:

x^2-50x-600 = (x-60)(x+10) = 0 => x = 60
x^2 - 5xp + 50p^2 = 3100

Differentiate with respect to time,

2xx' - 50x'p - 50xp' + 100pp' = 0
240 - 100(10) - 3000p' + 1000p' = 0

p' = -.38

mylen [45]

<span>To find the slope, you divide the difference of the y-coordinates of a point on a line by the difference of the x-coordinates. It is expressed as:

slope = (y2 - y1) / (x2-x1)
slope = 8-(-7) / 4 - 4
slope = 15 / 0
slope = undefined <------ SECOND OPTION

The line should be vertical where the slope is undefined. Hope this answers the question. Have a nice day.</span>
