Solve the differential equation dy/dx+4xy=x

Irina-Kira [14]

$\dfrac{\mathrm dy}{\mathrm dx}+4xy=x$
$\dfrac{\mathrm dy}{\mathrm dx}=x(1-4y)$

This ODE is separable, so you can write

$\dfrac{\mathrm dy}{1-4y}=x\,\mathrm dx$

Integrating both sides gives

$-\dfrac14\ln|1-4y|=\dfrac12x^2+C$
$\ln|1-4y|=-2x^2+C$
$1-4y=e^{-2x^2+C}$
$1-4y=Ce^{-2x^2}$
$y=\dfrac{1-Ce^{-2x^2}}4$

5(x+4)-3x+3=5 solve for x

Elena L [17]

Answer: X= -9

Step-by-step explanation:

Multiply the 5 by x+4 then copy the -3x+3=5. It will be 5x+20-3x+3=5.

Then subtract or add the like terms

5x-3x and 20+3. It will be 2x+23=5

Then add -23 to both sides

It will be 2x+23-23=5-23 then solve it will be 2x=-18 then divide both sides by 2 to find the value of x

2x/2=-18/2 then the final answer is x= -9. I hope it help

Is 2/3 greater then 5/8?

sineoko [7]

The LCD is 24

2 * 8 16
3 * 8 24

5 * 3 15
8 * 3 24

Because 16 over 24 is greater than 15 over 24
2/3 is greater than 5/8
