Eliminate the parameter and write a rectangular equation for:
x=t^2 + 3
y=2t
2007-08-26 13:23:52 · 6 answers · asked by Anonymous in Science & Mathematics ➔ Mathematics
t = y / 2
x = (y / 2) ² + 3
x = y ² / 4 + 3
4 x = y ² + 12

I've never heard of a rectangular equation. I think you mean write in rectangular coordinates.
t^2 = (y^2)/4 so x=(y^2)/4 + 3 or 4x-(y^2)-3 = 0

im nt sure if this is write but from what i did on my note pad it seems right im only 11 so dont be surprrised if its wrong
t = y / 2
x = (y / 2) ² + 3
x = y ² / 4 + 3
4 x = y ² + 12
If its write can you lz ote me as best answer

t=y/2
x=y^2/4+3
y^2=4x-12

t = y / 2..........substitute into the other...........x = ( y / 2)^2 +3 , or x = ( y^2) /4 +3

t = +- Sqrt( x - 3 )
y = +-2 * Sqrt( x - 3 )
+- means "plus or minus" I just don't know how to get the nice looking symbol in my answer yet.
