1. Parabola

2. Choice A

Step-by-step explanation:

1. We have been given the following parametric equations;

We first need to obtain the equation that connects x and y directly;

we solve for t in the first equation,

x = t + 3

t = x - 3

This implies that we shall substitute t with x - 3 in the second equation;

The graph of the function is shown in the attachment below. The conic section created by the parametric equations is thus a parabola.

2.

In the next question, the following parametric equations have been given;

It is much easier to solve for t in the second equation;

t is simply equals to y; t = y

The next step is to substitute t with y in the first equation;

We then square both sides to eliminate the square root;

Thus, choice A is the correct answer.

there are many solutions.

step-by-step explanation:

step 1: simplify both sides of the equation.

4x+6=4x^2+10x−4

step 2: subtract 4x^2+10x-4 from both sides.

4x+6−(4x^2+10x−4)=4x^2+10x−4−(4x^2+10x−4)

−4x^2−6x+10=0

step 3: factor left side of equation.

−2(2x+5)(x−1)=0

step 4: set factors equal to 0.

x=-5/2 or x=1

answer: no
