Question 2

Llana [10]

Hi here are the answers:)

Part A:

x = 3

Part B:

A = (3, 2)

Part C:

You can find the vertex by finding the mid-point of the focus and directrix. So the vertex is (-1, 2)

Part D:

The parabola opens left. This is because the parabola always opens toward the focus.

Part E:

The value of p is the distance from the focus to the vertex or the vertex to the directrix. To find p you can minus x-coordinate of focus with x-coordinate of the directrix, then divide it by 2. So this will be: -5-2/2 = -4

Part F:

p = -4

Part G:

$x=\frac{1}{4*-4}(y-2)^{2}-1$

Part H: image is attached down below. Fyi the C should be V (vertex)

Part I:

$x=\frac{1}{16} (y-2)^{2}-1$

*I'm not really sure about this one*

Part J:

1. x = 1/4 (y-3)>2+3

2. x = 1/12 (y +1)>2 +5

*I'm not really sure about this one either srry:(*

Hope this helped bai bye.

Anika [276]

Answer:

$y= 35+15x$

Step-by-step explanation:

Given data

It costs $35 for a membership

Monthly fee is $15

Let the number of months be x

and the total cost for x months be y
