Answer:
A. 
Step-by-step explanation:
The given parabola has vertex at (2,-5).
The equation of this parabola in vertex form is given by:
, where (h,k)=(2,-5) is the vertex of the parabola.
We substitute the values to get:

The graph passes through; (0,3).




Hence the equation of the parabola is

We expand this to get:


Since the outward region was shaded, the corresponding inequality is

The correct answer is A
Answer:
Three times the difference of two times a number and five is equal to 24, what is x?
Step-by-step explanation:
To write any equation in word problems, it is important to identify all your parenthesis operations by their technical names. Subtraction is a difference. So since we are multiplying it by 3, it becomes three times a difference.
Answer:
C
Step-by-step explanation:
If 9 members paid on the first day, this means they did not pay on the third day
The remaining people (everyone but the 9) paid on the third day
Therefore we must subtract to find out how many members paid on the third day
22 - 9 = 13
Each of the 13 members paid $12.80 which means we must multiply
13 × 12.80 = 166.40
In total, the grocery store collected $166.40 on the third day of the month
