Since <span>y = x2 - 8x + 12 is a quadratic equation, it is the same of y=ax²+bx+c
the main formula of the vertex is x= -b/2a, and y=f(-b/2a)
for our case x= -(-8) / 2=4, and f(4)= -4
the answer is </span><span>B. (4, -4)</span>

Answer:
option D is the correct answer
Answer: 9 boys and 12 girls
Step-by-step explanation:
21 * 3/7 = 9
21 * 4/7 = 12
''so add everything together and set it equal to 540. 13x-19+260=540
and solve for x. to solve for point p, plug in the x value, which is 13. 13(4) gives 92+2= 94.''
