Answer:
The temperature dropped 12 degrees over 3 hours. How much did it change each hour?
Step-by-step explanation:
This question (the answer) is asking you to do 12 divided by 3. That would be 12/3 (which is what was in the original question). Also, the temperature dropped, so that would be why it is -12/3
Option C: 
is the correct answer.
Explanation:
The given expression is 
We need to determine the factor of the expression.
Now, let us break the given expression into two groups.
Hence, we get,
Simplifying, we get,
Let us factor out 7g from the term 
Hence, we have,
Similarly, let us factor out -6h from the term 
Thus, we have,
Now, we shall factor out the term 
, we get,
Thus, the factorization of the given expression is
Therefore, Option C is the correct answer.

Answer:
Step-by-step explanation:
y = x^2 - x - 2 is a quadratic function. It's easily factorable: y = (x + 1)(x - 2). Setting this result equal to zero yields the x-intercepts: -1 and 2. This matches the x-intercepts shown on the graph.
The axis of symmetry, x = -b/(2a), derived from the coefficients 1, -1 and -2 of this particular function, is x = 1/2. This x = 1/2 is also the x-coordinate of the vertex. To find the y-coordinate of the vertex, we evaluate y = x^2 - x - 2 at x = 1/2, obtaining:
y = (1/2)^2 - (1/2) - 2, or y = 1/4 - 1/2 - 2, or -2 1/4. This does not quite agree with the y value (-2) shown in the diagram, but is close.
