Answer:
-6x^2-288
Step-by-step explanation:
18x - 432 - 18x - 6x² +144
Combine like terms
-6x^2+18x-18x-432+144
-6x^2-288
+ <span>The vertex of a parabola is (3,2),
that means the parabola's equation is y=a(x-3)</span>²+2
+ <span>A second point on the parabola is (1,5) and we replace x=1 and y=5. We have:
5</span>=a(1-3)<span>²+2 , so we have 4a=5-2 or a=3/4
So the equation is y=3/4 (x-3)</span>²+2
And by checking we have the point (5;5) is on the parabola

Answer: x(0.55)
Step-by-step explanation:
Because 45% of the price is being taking, off we are still paying for 55% of the market price, because 100%-45%=55%.
55/100=0.55
So the sale price is x(0.55)
