Answer:
C) The axis of symmetry is x = −1.5 and the vertex is (−1.5, 8.25).
Step-by-step explanation:
The axis of symmetry is x = − b/2a
= -(-3) / 2(-1)
= 3/(-2)
= -1.5
the vertex => x = -1.5
y= -(-1.5)²-3(-1.5)+6 =
-2.25 +4.5+6= 8.25

Answer:

Step-by-step explanation:
We are given that 20% of her calls, there is no answer or the line is busy.
So, remaining calls = 100% - 20% = 80%
Now we are given that She sells subscriptions to 6% of the remaining calls
So, she make a sale of calls = 
= 
= 
= 
= 
Hence she make a sale of
calls .
The answer would be 3, 6 times 3 is 18 and 18 minus 10 would be 8.
