How do I solve for y:<br> x²y² = 12/z²

Vika [28.1K]

Answer:

Y=Srt(12xs^2/z^2)

Step-by-step explanation:

Firstly

We multiply both sides with 1/x^2

We get

Y^2=12/z^2*1/x^2

Y^2=12x^2/z^2

Next: introduce a srt root

We have

Y=srt(12x^2/z^2)

Question part points submissions used solve the given differential equation by separation of variables. dx + e2xdy = 0

lina2011 [118]

Try this:
if given dx+e²ˣdy=0, then
$dy=- \frac{dx}{e^{-2x}} \ =\ \textgreater \ \ \int dy=-\int e^{-2x}dx; \ =\ \textgreater \ \ y= \frac{1}{2}e^{-2x}+C;$

How do you do this TwT

tangare [24]

Answer:

Step-by-step explanation:

First step plug the numbers into the equation.

-10/(5+2) = (-10/5) + (-10/2)

Solve both sides of the equation separately.

-10/(5+2) Use distributive property, multiply both 5 and 2 by -10.

= -50 + (-20) = -70

-10/5 + -10/2 Multiply the fractions so they can be added together.

-10/5*2 = -20/10 -10/2*5 = -50/10

-20/10 + -50/10 = -70

Now you have solved both equations and they are both equal to -70, so you have verified that the equations are equal to each other because they both equal -70.
