Obtain the general solution of<br> y ln x ln y dx + dy = 0

oksano4ka [1.4K]

Dy/dx = -y inx iny

(y in x in y) dx + dy = 0

(y in x in y ) dx = - dy

(in x )dx = - (1/ y in y) dy

you just need to integrate both sides

Hope this helps

Carlos takes classes at both Westside Community College and Pinewood Community College. At Westside, class fees are $ 98 per cre

Sholpan [36]

Answer:

x + y = 13

98x + 115y = z

Step-by-step explanation:

Let x represent the time spent taking class in Westside community college

Let y represent the time spent taking class in Pinewood community college

Let z represent the combined total amount paid for the class fees.

The total combined time for the two school is given as:

x + y = 13.

For the combined total amount; we multiply the price for each school with the time spent on the school and sum them together.

Westside: $98 * x = 98x$

Pinewood: $115 * y = 115y$

The combined total amount represented as z is given as:

z = 98x + 115y
