The non separable differential equation dy dx = 8x − 2y has a linear particular solution of the form y = mx + b. Find m + b.
yulyashka [42]

Answer:

m + b=2

Step-by-step explanation:

From the question we are told that

The non separable differential equation \frac{dy}{dx} = 8x - 2y

Generally the chi form of a give equation is mathematically represented as

\frac{dy}{dx} +P(x)y= q(x)

\frac{dy}{dx} + 2y = 8x

ye^2^x=\int e^2^.8xdxx

ye^2^x=8(\frac{xe^2^x}{2}-\frac{\int e^2^x}{2})

ye^2^x=8(\frac{xe^2^x}{2}-\frac{e^2^x}{1})+c\\

ye^2^x=4x^2^x-2e^2^x+c

y=4x-2+c

for c=0

y=4x-2

Therefore

m=4\\b=-2\\m + b=4-(+2)

m + b=2

Rita goes for a bike ride on a trail by her house. After 15 minutes of riding she sees a mile marker. When she reaches the third
lana66690 [7]

Given:

Rita covered 1 mile in 15 minutes.

She covered 3 miles in 30 minutes.

To find:

The rate at which she is riding.

Solution:

Let y be the number of miles covered in x minutes.

Rita covered 1 mile in 15 minutes. So, the point is (15,1).

She covered 3 miles in 30 minutes. So, the point is (30,3).

Slope of the line:

m=\dfrac{y_2-y_1}{x_2-x_1}

m=\dfrac{3-1}{30-15}

m=\dfrac{2}{15}

Therefore, she is riding \dfrac{2}{15} miles per minute.
