The vertex form: y = a(x - h)² + k
y = ax² + bx + c then h = -b/2a and k = f(h).
y = x² - 12x + 8
a = 1; b = -12; c = 8
h = -(-12)/(2·1) = 12/2 = 6
k = f(6) = 6² - 12·6 + 8 = 36 - 72 + 8 = -28
Answer: y = (x - 6)² - 28.
Answer:
12 inches ^2
Step-by-step explanation:
The area of a triangle is found by
A = 1/2 bh
A = 1/2 (6)*4
A = 12 inches ^2

Answer:
Step-by-step explanation:
Unless it was a restaurant for the king ..... i am going to assume your
200200 is 200
$1010 is $10
$5555 is $55
$78507850 is $7850
Let x be the number of $10 design set
$10 design set = x
$55 design set = 200 - x
10x + 55(200 - x) = 7850
10x + 11000 - 55x = 7850
55x - 10x = 11000 - 7850
45x = 3150
x = 70
200 - 70 = 130
70 of the $10 design and 130 of the $55 design
