HELP format is y=mx+b!!!!
Gekata [30.6K]

Answer:

y = - 3x - 3

Step-by-step explanation:

the equation of a linear function in slope- intercept form is

y = mx + b ( m is the slope and b the y- intercept )

To calculate m use the slope formula

m = (y₂ - y₁ ) / ( x₂ - x₁ )

with (x₁, y₁ ) = (- 2, 3) and (x₂, y₂ ) = (6, -21) ← 2 points from the table

m = \frac{-21-3}{6+2} = \frac{-24}{8} = - 3

y = - 3x + b ← is the partial equation

To find b substitute any other point from the table into the partial equation

using (2, - 9), then

- 9 = - 6 + b ⇒ b = - 9 + 6 = - 3

y = - 3x - 3 ← linear relationship

The general solution of 2 y ln(x)y' = (y^2 + 4)/x is
Sav [38]

Replace y' with \dfrac{\mathrm dy}{\mathrm dx} to see that this ODE is separable:

2y\ln x\dfrac{\mathrm dy}{\mathrm dx}=\dfrac{y^2+4}x\implies\dfrac{2y}{y^2+4}\,\mathrm dy=\dfrac{\mathrm dx}{x\ln x}

Integrate both sides; on the left, set u=y^2+4 so that \mathrm du=2y\,\mathrm dy; on the right, set v=\ln x so that \mathrm dv=\dfrac{\mathrm dx}x. Then

\displaystyle\int\frac{2y}{y^2+4}\,\mathrm dy=\int\dfrac{\mathrm dx}{x\ln x}\iff\int\frac{\mathrm du}u=\int\dfrac{\mathrm dv}v

\implies\ln|u|=\ln|v|+C

\implies\ln(y^2+4)=\ln|\ln x|+C

\implies y^2+4=e^{\ln|\ln x|+C}

\implies y^2=C|\ln x|-4

\implies y=\pm\sqrt{C|\ln x|-4}
