marusya05 [52]
It is given in this item that the subject of interest has to pay the single coverage for the medical insurance and is given to be equal to $322.77. 

Let x be the number of hours that a person should work in order to pay for the cost of the medical insurance. The value of this variable is calculated by dividing the total insurance cost by the amount that a person earns every hour.

                             x = $322.77 / ($10/hr)
                             x = 32.277 hours

Therefore, the number of hours that a person should work is equal to 32.277 which is approximately equal to 32 hours and 17 minutes.

Please help

Answer:

<h2>        y = x² - 1</h2>

Step-by-step explanation:

y = -1 for x = 0 {point(0, -1)} means -1 at the end of formula

If we add 1 to y-coordinate of  every given point we get the squares of x-coordinate:

(1, 0):   1² - 1 = 0

(2, 3):   2² - 1 = 4 - 1 = 3

(3, 8):   3² - 1 = 9 - 1 = 8

(4, 15):   4² - 1 = 16 - 1 = 15

So for any x:

(x, y)   y = x² - 1
