Question

Eliminate the parameter, t, and write a rectangular equation for
x =t^2 +3 and y = 2t.

Answer 1

\[x = \frac{y^2}{4} + 3 \]

Answer 2

I eliminated t

Answer 3

I killed t ... I am math serial killer

Answer 4

i got t = \[\sqrt{3-x}\]

Answer 5

you said eliminate t not y

Answer 6

yeah to x = \[t ^{2} + 3\]
then t\[t ^{2} = 3-x\]
tehn t = \[\sqrt{3-x}\]

Answer 7

How do you write a rectangualr equation??

Answer 8

ah I really don't know what is rectangular equation ...

Answer 9

oh ok...but then to find y since y=2t what is \[2 (\sqrt{3-x}\]

Answer 10

maybe it means parabola's equation

Answer 11

how do i distribute the 2 to the radical?

Answer 12

use my equations to find y

x = y^2/4 + 3
4x = y^2 + 12
\[\sqrt{4x - 12 } =y \]
