What you meant was the "commutative" property.
So we can say that when adding:
<em>"<u>Commutative</u> means that the order does not make any difference in the result."</em>
Example:
5 + 6 = 6 + 5
a + b = b + a
The commutative property does not hold for subtraction.
Example:
4 - 1 ≠ 1 - 4
a - b ≠ b - a
Ok, now does the commutative property hold true for multiplication?
2 x 3 = 3 x 2
2 x 3 x 4 = 4 x 3 x 2
Yes.
What about division?
12 ÷ 4 ≠ 4 ÷ 12
The commutative property does not hold for division.
Answer:
The number of DVD's is 6.
Step-by-step explanation:
Given:
Grace bought a television for $329.
Some DVDs for $5.75 each.
She spent total of $363.50
Now, to find out the number of DVD's Grace bought.
Let the number of DVD's be 
So, cost of DVD's =
Cost of television = $329.
Total amount spent = $363.50.
According to question:
Now, putting the equation to solve:
<em>Subtracting with 329 on both sides we get:</em>
<em>Dividing both sides by 5.75 we get:</em>
Therefore, the number of DVD's is 6.
The parent function of the function g(x) = 3cos (x + 180°) + 1 is f(x) = cos(x)
<h3>What are parent functions?</h3>
Parent functions are the basic function that represents the entire family of that function family
<h3>How to determine the parent function?</h3>
The function is given as;
g(x) = 3cos (x + 180°) + 1
As a general rule, the parent function of any function is the basic equation of the function family
The basic equation of the function g(x) = 3cos (x + 180°) + 1 is f(x) = cos(x)
Hence, the parent function of the function g(x) = 3cos (x + 180°) + 1 is f(x) = cos(x)
