Answer: it is slope intercept form

Example: y= 5x + 8

this means that 5x is the slope so when graphed, you would go 5 up and 1 over (you can think of it as 5/1) and the 8 signifies the y- intercept. The y- intercept indicates where you start graphing

For the differential equation dy/dt=ky, k is a constant, y(0)=24, and y(1)=18. What is the value of k?
Gre4nikov [31]

The equation is separable, so solving it is trivial:

\dfrac{\mathrm dy}{\mathrm dt}=ky\implies\dfrac{\mathrm dy}y=k\,\mathrm dt

Integrating both sides gives

\ln|y|=kt+C\implies y=e^{kt+C}=Ce^{kt}

Given y(0)=24 and y(1)=18, we find

24=C

18=Ce^k=24e^k\implies e^k=\dfrac34\implies k=ln\dfrac34

so the answer is E.

30 POINTS FOR SIMPLE QUESTION
Komok [63]

-4 = y + 3


y = -4x - 3


 Solve for Y in the first equation:

-4 = y +3

Subtract 3 from both sides:

y = -7

Now using the addition method:

rewrite the second equation as 4x+y = -3


Multiply y = -7 by - 1 to get -y = 7

Now add the two together:

4x +y = -3

    -y =7

4x = 4

Divide each side by 4:

x = 4/4 = 1


Then replace x in one of the equations to solve for y which is -7

X = 1, Y = -7
