79 cents marked down 15%
so
79 x (1 - 0.15)
79 x 0.85 = 67 cents
plus <span>Sales tax is 5.5%
67 x (1.055) = 71 cents
answer
71 cents</span>

Answer:
THE answer is y= -2x²+16x-24
Step-by-step explanation:
OK, so the standard form for an equation is ax²+bx+c
When you look at the equation we see that there is a -2 all by itself so we need too bring it within the parenthesis, so we'll distribute it..... so now instead of 2(x-6), we have -2x-12..........Why? because (2 times x is 2x and 2 times six is 12)
next when you write it ALL out, you get (-2x+12)(x-2) now we need to put this in the standard form by using the FOIL method
F- first O-outer I-inner L-last..... so multiplying the First from both equations we get -2x², Outer is -2x times -2 which is 4 because two negatives make a positive, Inner is 12 times x which is 12x, Last is 12 times -2 whchis -24. Put them all together and you get. 2x²+12x+4x- 24, now we combine like terms (in bold) and we get -2x²+16x-24. Look at the standard form i gave above and see how the final answer matches
-2x²+16x-24
ax² +bx + c
