Answer:

x=13

y=14

Step-by-step explanation:

We know that angle JNK is equal to angle MNL. We also know that angle JNK and angle KNL are supplementary.

Knowing this, we can write two equations: 4x-1=3y+9 and (4x-1)+(2x+6y+19)=180. We can solve for y in the first equation. Subtracting 9 from both sides gives us 4x-10=3y. Dividing both sides by 3 gives us \frac{4x-10}{3} =y.

We can plug that in to the second equation to get (4x-1)+(2x+6(\frac{4x-10}{3} )+19)=180. Expanding the second parenthesis, we get 2x+8x-20+19 which equals (10x-1). We now have (4x-1)+(10x-1)=180. Expanding gives us 14x-2=180. Adding 2 to both sides gives us 14x = 182. Dividing both sides by 14 gives us x=13.

We can now plug 13 into the above equation to solve for y. y= \frac{4*13-10}{3} Solving that gives you y=14.

Explain why a quadratic function is a reasonable model for revenue. choose the correct answer below.
Andrei [34K]
Revenue = Sales Volume (x) times Price. Price depends on volume sold: the more you are willing to sell per week, the lower your average price will have to be to get them all sold. 

<span>eg, if there are a fixed number of buyers with a variety of incomes, then you might be able to sell the first 10 per month for £30 each through the up-market High Street jeweller. If you want to sell an extra 10 per month you might have to reduce the price to £15 and sell them through Asda/WalMart. And to move another 10 per month you may have to sell them from a street stall at £5 each! </span>
