Convert to vertex form.
Whitepunk [10]

Answer:

<em>f</em>(x) = (x + 4)² - 13

Step-by-step explanation:

You will have to "complete the square [½B]²" to figure this out. Here is how you would set it up:

(x + 4)² → x² + 8x + 16

x² + 8x + 16 - 13 → x² + 8x + 3 [TA DA!]

We know that our vertex formula is correct. Additionally, that <em>-</em><em>h</em><em> </em>gives you the OPPOSITE terms of what they really are, and <em>k</em><em> </em>gives you the EXACT terms of what they really are. Therefore, your vertex is [-4, -13].

I am joyous to assist you anytime.

A store offers a 15% discount on all items in the store during a sale. All store employees get an additional 10% employee discou

0.765 (100) + .06 (.0765 x 100)
76.5  + .06 (76.5)  
76.5 + 4.59 = 81.09    Chris will pay $81.09

A better way ( if you don't care to know the tax just the bottom line of what it will cost) would be to do:

0.765x x 1.06 = 76.5 x 1.06 = $81.09 too.

Why the 1 in front of the .06?  The one includes the price of the coat so you don't have to add the tax on after.
Think about it like this. When you buy something you pay (even with an employee 
discount) for all of it (100%) + the tax (in this case, it's 6%)  So you pay 106% of the cost of the item.  106% = 1.06
