(adsbygoogle = window.adsbygoogle || []).push({}); 1. The problem statement, all variables and given/known data

Given that:

8y[tex]^{2}[/tex] + 4y = -4x + 6

x + y = 4t

where x and y are in metres, and t is in seconds.

If y is positive, what is the magnitude of the velocity when t = 0.1875s?

2. Relevant equations

N/A

3. The attempt at a solution

I am a little unsure on how to start.

I think I have to differentiate:

8y[tex]^{2}[/tex] + 4y = -4x + 6

Using implicit, then sub in x + y = 4t

And solve for x and y.

If all that is right, which I doubt it is. I then have to some how find the magnitude of velocity, which I am unsure how to do.

Any and all help would be greatly appreciated. :D
