Question

MEDALS AWARDED

eliminate the parameter. x = square root of t y = 2t + 5

Answer 1

\[x=\sqrt{ty}\]

Square it and solve for t

Answer 2

Okay but I need a y = equation @AravindG

Answer 3

Once you can get t substitute in the equation.

Answer 4

Options:

a. y = 2 sqrt x+ 5, x ≥ 0
b. y = 2 sqrt x - 5, x ≥ 0
c. y = 2x2 + 5
d. y = 2x2 - 5

Answer 5

How do I find t?

Answer 6

@hartnn

Answer 7

x = sqrt t
square both sides
u will get t


now plug this t in your y= ... equation

Answer 8

@hartnn x = square root of t y

Answer 9

not actually
its the way she has written, its confusing
actually x= sqrt t
and
y=2t+5

Answer 10

oh ..Please use eqn editor next time

Answer 11

looking at tue choices, I m pretty sure about that

Answer 12

Sorry. But yeah, @hartnn is right about how it's written.

Answer 13

did u get t in terms of x?

Answer 14

Ha okay, wait. The answer is c (y = 2x2 + 5 ). Right?

Answer 15

yes:)

Answer 16

Thank you :)
