Use the equation y=1/3x-2<br> Draw a graph of the line, and identify the slope and Y intercept

xz_007 [3.2K]

I can't graph the equation for you, but I can tell you where the points will be. The y-intercept is easy; 1/3×0=0 and 0-2= -2. One of your points (the y-intercept) should be at (0,-2). To find another point is slightly trickier, but all you have to do here is find a multiple of three. For the simplest one, go to 3 on the x-axis. Then, apply the equation, y=1/3x-2. Your second point should lay at (3,-1). Then, just connect those two points and extend them to show that the line is continuous. Hope I could help!

Find the solution of the differential equation that satisfies the given initial condition. dy/dx = xe^y, y(0) = 0

Anna [14]

$\dfrac{\mathrm dy}{\mathrm dx}=xe^y$
$e^{-y}\,\mathrm dy=x\,\mathrm dx$
$-e^{-y}=\dfrac{x^2}2+C$

$y(0)=0$
$\implies-1=C$
$\implies -e^{-y}=\dfrac{x^2}2-1$
$e^{-y}=1-\dfrac{x^2}2$
$-y=\ln\left(1-\dfrac{x^2}2\right)$
$y=-\ln\left(1-\dfrac{x^2}2\right)$

⚫We have to find out the value of $1 \frac{2}{3} \div 6$

⚫So we have to convert it like this first,

$\frac{5}{3} \div 6$

⚫Do reciprocal to change the sign of divide into multiply

$\frac{5}{3} \times \frac{1}{6}$

⚫By doing this, we will get

$\frac{6}{18}$

Simplify this,

$\frac{1}{3}$

⚫⚫So our answer will be $\frac{1}{3}$
