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.

Y-x=15 y-x=5 using elimination
Galina-37 [17]

Answer:

No solution

Step-by-step explanation:

To eliminate is to get rid of one of the variables.

You can choose to either add each term in the equations or subtract each term in the equation.

For a variable to be eliminated, there must one pair that have the same constant with it. Each equation already has the same constant with a variable.

Try adding them.

.     y - x = 15

<u>+    y - x = 5</u>

2y - 2x = 20   No variables were eliminated.

Try subtracting.

.     y - x = 15

<u>-     y - x = 5</u>

0y - 0x  = 10   All variables were eliminated.

.         0 = 10     This is false.

This system of equations cannot be solved.

Graphically, these two lines would have the same slope and are parallel. The solution to a system is same as the point of intersection. Parallel lines never meet, never intersect, therefore there is no solution.

100 POINTS FOR BRAINLIEST! according to the image, whats the answer? Answer wisely for the full 100
lesantik [10]

Answer:

Step-by-step explanation:

To find the area of a semicircle the formula is

\frac{\pi r^2}{2} \\=\frac{\pi 1^2}{2} \\=6.283m^2

The square

A=a^2=2^2=4m^2\\6.283+4=10.283m^2

A=wl=7*9=63m^2 (rectangle)

A=\frac{ab}{2} =\frac{6*4.5}{2} =13.5m^2\\63+13.5=76.5m^2 (triangle)
