Answer:

  y' = -y/x

Step-by-step explanation:

It looks like you have ...

  e^z -z = 0 . . . . . where z = xy

Differentiating with respect to x gives ...

  z'·e^z -z' = 0

  z'(e^z -1) = 0

The zero-product rule tells you this is true for e^z = 1, which is not useful for finding y', and for z' = 0, which is.

  z = xy

  z' = y +xy' = 0

  y' = -y/x

_____

<em>Additional comment</em>

There appear to be no real values of x and y that will make your equation true.

Looking to solve (Ac+b-d)(a^2-c)=
Sunny_sXe [5.5K]

It should be noted that the expansion of the equation (ac+b-d)(a² - c) will be a³c + ac² + a²b - bc - a²d + cd.

<h3>How to illustrate the information?</h3>

It should be noted that an equation is used to show the relationship that occur between the variables that are illustrated.

In this case, it should be noted that the equation

(ac+b-d)(a² - c) will be solved accordingly. This will be:

(ac+b-d)(a² - c)

Open the parentheses

a³c + ac² + a²b - bc - a²d + cd

Therefore, it should be noted that the expansion of the equation (ac+b-d)(a² - c) will be a³c + ac² + a²b - bc - a²d + cd.

Do question 40 please i need help show your work please i need help so bad
zimovet [89]
So 15% is out of 100%, and the cab company has sent 30 cabs out of x?(x is the total number of cabs). \frac{15}{100} =  \frac{30}{x}

So, by setting up that data we already know, we can make this equation to figure out how many cabs total the company actually has:

<span>15x = 100 * 30
</span>
We do the multiplication on the right side

15x = 3000

And divide to isolate the "X" variable

x = 200

So, the cab company has 200 cabs total, and they sent out 30 of them.

Solve 2x-11 = k for x
LenKa [72]

2x-11 = k

add 11 to each side

2x-11+11 = k+11

2x = k+11

divide each side by 2

x = (k+11)/2
