STUCK AGAIN Reply to this Post

Professor Skinner,
I'm stuck again. My book seems to be filled with "stump the chump" problems. Not sure how to do the following:

Eliminate the parameter of the curve given by x=t+5,=t^2+3


Your help is always much appreciated!

Cindy

I assume you mean: x=t+5 and y=t^2+3. Solve for t in the first equation, getting t=x-5, and substitute that value of t into the second equation:

y=(x-5)^2+3.

This eliminates the parameter t.
