Suppose the price p, in dollars, and number of sales, x, of an item is related by 5 8 6 50 p x px + + = . If p and x are functio

Natali5045456 [20]

Answer:

According to the information of the problem x = 15 , p=2.90 and dp/dt = -1.15

then $\frac{dx}{dt} = -3.357\\$

Step-by-step explanation:

Since everything is changing with respect to time and $p,x$ are related according to the following equation

$5p+5x+3px = 71$

We need to find the implicit derivative with respect to the time. And we get the following.

$5\frac{dp}{dt}+5\frac{dx}{dt}+3x\frac{dp}{dt}+3p\frac{dx}{dt} = 0$

$\frac{dx}{dt}$ is what we don't know, so we solve for it and get

$\frac{dx}{dt} = - (5\frac{dp}{dt}-3x\frac{dp}{dt})/ (5+3p)$

Now. According to the information of the problem x = 15 , p=2.90 and dp/dt = -1.15

then $\frac{dx}{dt} = -3.357\\$

6x + 14 = 7 - x А. В. ДІ 1 D. I NA Huh?

ipn [44]

Answer:

x = -1

Step-by-step explanation:

6x + 14 = 7 - x

Add x to each side

6x+x + 14 = 7 - x+x

7x+14 = 7

Subtract 14 from each side

7x+14-14 = 7-14

7x = -7

7x/7 = -7/7

x = -1
