How do you solve for Y in x=5 +8y-8

Rzqust [24]

x = 5 + 8y - 8

Combine like terms.

x = -3 + 8y

Add 3 to both sides.

x + 3 = 8y

Divide both sides by 8.

y = $\frac{x+3}{8}$

Solve the decay equation y' = -ky using the integrating factors method. Show work

Alex777 [14]

Answer:

$y=\frac{c}{e^{kx}}$

Step-by-step explanation:

$\frac{\mathrm{d} y}{\mathrm{d} x} =-ky$

$\frac{\mathrm{d} y}{\mathrm{d} x} +ky=0$

comparing with equation

$\frac{\mathrm{d} y}{\mathrm{d} x} + Py=Q(x)$

$I.F.= e^{\int P dx}$

$I.F.= e^{\int k dx}$

$I.F.= e^{kx}$

$y=\frac{1}{I.F.} ( \int {Q(x)} dx +c)$

$y=\frac{1}{e^{kx}} ( \int {0} dx +c)$

$y=\frac{c}{e^{kx}}$
