victus00 [196]

Step-by-step explanation:

Health insurance covers essential health benefits critical to maintaining your health and treating illness and accidents

Health insurance protects you from unexpected, high medical costs.

You pay less for covered in-network health care, even before you meet your deductible.

You get free preventive care, like vaccines, screenings, and some check-ups, even before you meet your deductible.

If you have a Marketplace plan or other qualifying health coverage through the plan year 2018, you don’t have to pay the penalty that people without coverage must pay.

Answer:

The price of price of the stock after it has been owned for 12 weeks is $92.55

Step-by-step explanation:

Given: The price of a particular stock is represented by the linear equation

y = -0.91x + 103.47

where x represents the number of weeks the stock has been owned and y represents the price of the stock, in dollars.

We have to find the price of price of the stock after it has been owned for 12 weeks.

Since , x represents the number of weeks the stock has been owned.

Thus, by substitute, x = 12

We get the value of y , the price of stocks.

Thus, y(x) =  -0.91x + 103.47

⇒ y(12) =  -0.91(12) + 103.47

⇒ y(12) =  -10.92 + 103.47

Solving , we get,

⇒ y(12) = 92.55

Thus, the price of price of the stock after it has been owned for 12 weeks is $92.55.
