Question

Eliminate the parameter.

x = radical t , y = 2t + 5

Answer 1

I just started learning this, so you have\[x=\sqrt{t}\]and\[y=2t+5\]So you can get t by itself in x=sqrt t\[x=\sqrt{t}=>x ^{2}=t\]Plug t into y=2t+5\[y=2(x ^{2})+5\]

Answer 2

so you just get t by itself and plug it in?

Answer 3

I think so, and when graphed, you have to make sure only graph where t exists.

Answer 4

Thank you! That was pretty easy haha also lets say i have an x=7t, for my next question, would the x be x=x/7?

Answer 5

Did it just give you x=7t?

Answer 6

No other equation?

Answer 7

no x=7t, y=t+4
but i think the answer is y= x/7 +4
is that right?

Answer 8

Yeah
