she had 6 grandchildren and she used $9 for one grandchild so we multiply
9 x 6 = $ 54
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:
-1 , 1 , 3 , 5 , 7
Step-by-step explanation:
An = = 2n - 3
n = 1; A1 = 2*1 - 3 = 2 - 3 = -1
n =2; A2 = 2*2 - 3 = 4 - 3 = 1
n = 3; A3 = 2*3 - 3 = 6 - 3 = 3
n= 4; A4 = 2*4 - 3 = 8 - 3 = 5
n = 5; A5 = 2*5 - 3 = 10 - 3 = 7
