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.
12+6=18 18+18=36 total coins.
12 quarters:36 coins.
To simplify divide each side by 12.
12/12=1 36/12=3
The simplified ratio is 1:3.
Therefore the answer is B.
Hope this helps! (:
Answer:
n > 3
Step-by-step explanation:
Given
3n + 6 > 15 ( subtract 6 from both sides )
3n > 9 ( divide both sides by 3 )
n > 3
Answer:
the slope of function A is less than the slope of function B because 1/4 <1
