Which of the following is the general solution of the differential equation dy dx equals the quotient of 4 times x and y?

katovenus [111]

The ODE appears to be

$\dfrac{\mathrm dy}{\mathrm dx}=\dfrac{4x}y$

It's separable; we can write

$y\,\mathrm dy=4x\,\mathrm dx$

and integrating both sides yields

$\dfrac{y^2}2=2x^2+C$

$\implies y^2=4x^2+C$

What is the equation of the line that passes through the point(1,7) and has a slope of -1

zhuklara [117]

Answer:

y = -1x + 8

Step-by-step explanation:

(1,7)

y = mx + b

7 = -1 × 1 + b

solving for b:

b = 7 - (-1)(1)

b = 8

Therefore,

y = -1x + 8
