Associative property of addition is used when you want to group addends.
This is mainly used to cluster set of numbers or in this case, addends. How do
you use the associative property when you break apart addends? Simple you group
them using the open and closed parentheses or brackets. Take for an example 1 +
1 + 2 = 4. Using the associative property you can have either (1 + 1) + 2 = 4
or 1 + (1 + 2) = 4 clustered into place.
Answer:
Step-by-step explanation:
It is the same process as in previous problems.
Once the origin is the point (0, 0):
So basically, the first question after the word problem is asking you to write an equation to represent the value of Mama's car after a certain amount of years (t). Since the value of her car decreases by 3% each year, you could multiply 3% by the original value of her car, to find what 3% is, OR you could subtract 19,400 (the value of her car after 1 year) from 20,000 INSTEAD of multiplying 20,000 by 3%.
Equation: value=20,000 - 600t
To answer the next question, just plug it into the equation you created.
500<20,000 - 600t
-19500< -600t
32.5>t
Final Answer: It would take at least 32 and 1/2 years for the value of Mama's car to be less than $500.
Hope this helps!! :)
Answer:
It's +2
Step-by-step explanation:
As the positive occurs on the right side of the negatives in the number line so if we keep extending on the right side so we get +2
