"Increasing" and "decreasing" are references to what the y-values do when the x-values increase.
Attached is a copy of all four tables, marked with whether the y-values increased or decreased on each step (and it also shows how much that increase or decrease was.
The only table that does this is the top right table in the attachment, which is your second table.
we know that
The vertex of the function is the point
The vertex of the function is the point
The x-coordinate of the vertex is equal to h
the y-coordinate of the vertex is equal to k
so
the value of h is
the value of k is
the equation is
therefore
<u>the answer is the option a</u>
Answer: There are 249 times Jamie takes a counter from the bag.
Explanation:
Since we have given that
Ratio of colour of red to blue to green is 1:3:7.
Number of blue counters = 68
Let the total number of times Jamie does from the bag be x.
So, According to question,
Hence, there are 249 times Jamie takes a counter from the bag.
