Basically you do fractions side by side. so, 6/3=15/h and then cross multiply to get your answer so that would give you 3h=80, then divide 80÷3

Find dy/dx by implicit differentiation for x – y = xy.

frez [133]

Answer:

$\frac{dy}{dx}$ = $\frac{1-y}{1+x}$

Step-by-step explanation:

Differentiate xy using the product rule, then

Given

x - y = xy

1 - $\frac{dy}{dx}$ = x. $\frac{dy}{dx}$ + y. 1 = x $\frac{dy}{dx}$ + y ( subtract 1 from both sides )

- $\frac{dy}{dx}$ = x $\frac{dy}{dx}$ + y - 1 ( subtract x $\frac{dy}{dx}$ from both sides )

- $\frac{dy}{dx}$ - x $\frac{dy}{dx}$ = y - 1 ( multiply through by - 1 )

$\frac{dy}{dx}$ + x $\frac{dy}{dx}$ = 1 - y

$\frac{dy}{dx}$ (1 + x) = 1 - y ← divide both sides by (1 + x)

$\frac{dy}{dx}$ = $\frac{1-y}{1+x}$

Oh my gosh <br> I don't have no idea, <br><br> Please help and don't forget to show your work.

A=LW
7x^3-42x^2=L(7x^2)
7x^2(x-6)=L(7x^2)
divide both sides by 7x^2
x-6=L
legnth=x-6

Can u answer this? (you can do it!)

Leto [7]

Hello!

A circular pan is the same as a circle

To find the area of a circle you use the equation

$\pi r^{2}$

r is radius which is half the diameter

put in 3.14 for pi and the radius

3.14 * $4^{2}$

square the 4

3.14 * 16

Multiply

The answer is 50.24

Hope this helps!
