Answer:
B. Commutative Property of Multiplication
Step-by-step explanation:
The slope of the line is the velocity, or rate of change, of y with respect to x. In other terms, the slope tells you how much y will change for every change in x by one unit. For example if the slope, which is velocity, is 2. y will increase by two units every time x increases by one unit. Your graph is not pictured nor explained, so I cannot give you the specific context beyond the principle that the slope of a line is a constant velocity or rate of change.
Answer:


Step-by-step explanation:
Given

Solving (a): Equation when it hits the ground.
This means that 
So, we have:


Solving (b): The value of t in (a)

Using quadratic formula, we have:

This gives:




Split



Time can't be negative; So:

If the table is:
x | y
------
1 | 76
------
2 | 92
---------
3 | 108
-----------
4 | 124
-------------------------------------------------------------------------------------------------------------------
Find the change inbetween each amount per week
92 - 76 = 16
108 - 92 = 16
etc.
This means that her initial deposit should be subtracting 16 from her first deposit.
76 is the amount first deposited
76 - 16 = 60
A) $60 should be your answer
hope this helps
