1) What are the co-vertices of the following graph?

(0, 1) and (0, -1)

(1, 0) and (-1, 0)

(0, 8) and (0, -8)

(8, 0) and (-8, 0)

2) What is the equation of the following graph?

(x+1)^2/9 - (y-2)^2/16 = 1

(x-1)^2/9 - (y+2)^2/16 = 1

(y+2)^2/16 - (x-1)^2/9 = 1

(y-2)^2/16 - (x+1)^2/9 = 1

3) What is the center of the following graph?

(1, -2)

(4, -2)

(-1, -2)

(2, 0)

S

Step-by-step explanation:

a. she will receive a refund of $278.

step-by-step explanation:

y = 2x

step-by-step explanation:

if you divide each number in the sequence, you'll see that they all have a multiple factor of 2. each number in the series, and any other numbers which may continue, will be multiplied by 2. therefore, y is the next number in the sequence, and x is the current one, so, our formula will be y = 2x.
