This is a linear differential equation of first order. Solve this by integrating the coefficient of the y term and then raising e to the integrated coefficient to find the integrating factor, i.e. the integrating factor for this problem is e^(6x). 
<span>Multiplying both sides of the equation by the integrating factor: </span>

<span>(y')e^(6x) + 6ye^(6x) = e^(12x) </span>

<span>The left side is the derivative of ye^(6x), hence </span>

<span>d/dx[ye^(6x)] = e^(12x) </span>

<span>Integrating </span>

<span>ye^(6x) = (1/12)e^(12x) + c where c is a constant </span>

<span>y = (1/12)e^(6x) + ce^(-6x) </span>

<span>Use the initial condition y(0)=-8 to find c: </span>

<span>-8 = (1/12) + c </span>
<span>c=-97/12 </span>

<span>Hence </span>

<span>y = (1/12)e^(6x) - (97/12)e^(-6x)</span>

Blake solved the following division exercise : 136 divided by 3 = 44 R4. Explain how you know the answer is wrong just by lookin
son4ous [18]
The remainder (which is what Blake says is the remainder), can never be more than the number you are dividing by (the dividend), which in this problem is three.

Divide 136 by 3 and you will prove that answer is incorrect.

What 2/10 repensnets in percent form?
Sonja [21]
2/10 represents 20 percent, as 10 is 100% because it is the Max, so something like 4/10 would be considered 40%
