Answer:
Option 4 - The expression is equivalent to 12 + 3 + (-7) because of the commutative property.
Step-by-step explanation:
To find : Which statement is true about the expression 
?
Solution :
Associative property states that, 
Commutative property states that, 
By definition of properties we conclude that option 4 applies the correct property i.e. commutative.
As 
Therefore, The expression is equivalent to 
because of the commutative property.
So, Option 4 is correct.
Answer: The parabola has its concavity downwards, so we need a function in the model:
With a negative value of 'a'
The vertex is (0,0), so we have that:
The x-coordinate of the vertex is given by the equation:
So we have a function in the model:
With a < 0
The only option with this format is B:
