Solve for x<br> 4(x−3)=8(x−1)

ikadub [295]

Answer:

x=-1

Step-by-step explanation:

4(x−3)=8(x−1)

Distribute

4x - 12 = 8x -8

Subtract 4x

4x-12 -4x= 8x-8-4x

-12 = 4x-8

Add 8 to each side

-12+8 = 4x-8+8

-4 = 4x

Divide by 4

-4/4 = 4x/4

-1 =x

Suppose f(x, y) is a differentiable function of x and y and let g(r, s) = f (2rs, 8s − 2r). Use

worty [1.4K]

By the chain rule,

$\dfrac{\partial g}{\partial r} = \dfrac{\partial f}{\partial r} \\\\ ~~~~~ = \dfrac{\partial f}{\partial x} \dfrac{\partial x}{\partial r} + \dfrac{\partial f}{\partial y} \dfrac{\partial y}{\partial r} \\\\ ~~~~~ = 2 s \dfrac{\partial f}{\partial x} - 2 \dfrac{\partial f}{\partial y}$
