Answer:
k = -12/77
Step-by-step explanation:
OG problem: k(3k−6)−7k(6k+10)=12
Step-by-step:
3k - 6k - 42k - 70k = 12
-3k - 42k - 70k = 12
-7k - 70k = 12
-77k = 12
k = -12/77
Vertex is now at (-1,5)
for
y=a(x-h)^2+k
vertex is (h,k)
so veertex is (-1,5)
y=a(x-(-1))^2+5
y=a(x+1)^2+5
a is a constant, we will asssume that it is 1 because all the choices have 1
y=1(x+1)^2+5
y=(x+1)^2+5
2nd option
We are to select 2 people to sit in first row from 6.
This is a problem of Combinations. We are find permutation of 6 people taken 2 at a time. This can be represented as 6C2.
So, the answer is option B
