Eliminate the parameter “t” for the parametric equations, where 0 < t < 5. x = √5t

y = 2t — 2

Answers:

A) y = 2/5x^2 — 2
B) y = 5/2X^2 — 5
C) y = 2√5x — 2
D) y = 2/5x^2 — 2

A) y = 2/5x^2 — 2

Step-by-step explanation:

We are given the parametric equation:

To express y in terms of x, we solve for t in the first equation and substitute in the second equation.

Squaring:

Solving for t:

Substituting in the second parametric equation:

Correct choice: A) y = 2/5x^2 — 2

3. (5x + 1) - (-10x + 6)

simplify the answer choice. combine like terms. remember to distribute the negative to the terms inside the second parenthesis. also remember that two negatives = one positive, and one of each sign = negative.

- (-10x + 6) = + 10x - 6

simplify. combine like terms:

5x + 1 + 10x - 6

5x + 10x + 1 - 6

15x - 5

∴ it is your answer
