2x + 8 = -4 solve for c Show work please

Mathematics
1 answer:
andrew-mc [135]3 years ago
7 0

Answer: x=-6

Step-by-step explanation:

Given

2x + 8 = -4

Subtract 8 on both sides

2x + 8 - 8 = -4 - 8

2x = -12

Divide 2 on both sides

2x / 2 = -12 / 2

x = -6

NOTE: I assume the questions "solve for c" actually means "solve for x"

Hope this helps!! :)

Problem1 The behavior of a physical system can be described by the following first order differential equation: dy/dt=2y +t^2
daser333 [38]

Answer:

y = \dfrac{t^3e^{2t}}{3}+Ce^{2t}.

Step-by-step explanation:

Using first order linear differential equation:

\dfrac{\mathrm{d} y}{\mathrm{d} t} = 2y + t^2

\frac{\mathrm{d} y}{\mathrm{d} t} - 2y =t^2

finding integrating factor:

I.F = e^{\int -2dt}

I.F =e^{-2t}

now,

y = \dfrac{1}{IF}(\int t^2dt+ c )

y = \dfrac{1}{e^{-2t}}(\int t^2dt+ c )

y = \dfrac{t^3e^{2t}}{3}+Ce^{2t}

hence the solution is

y = \dfrac{t^3e^{2t}}{3}+Ce^{2t}
