By definition, we have to:

 In mathematics, the commutative property or commutativity is a fundamental property that has some operations according to which the result of operating two elements does not depend on the order in which they are taken.

 This is fulfilled in ordinary addition and multiplication: the order of the addends does not alter the sum, or the order of the factors does not alter the product.

 We have then, that the commutative property of the addition is:
 3 + (-7) = (-7) + 3

 Answer:
 
An expression that illustrates the commutative property of addition is:
 
3 + (-7) = (-7) + 3

Which relationship between x and y in the equation shows a proportional relationship?
denis23 [38]
Yap,

It seems to me that there are two answers. Both y = .5x and y = 12x. Direct variation is what I'm thinking of so hopefully this helps.

BTW - with Direct Variation, the line will go through (0, 0).

The newly elected president needs to decide the remaining 5 spots available in the cabinet he/she is appointing. If there are 15
skad [1K]

Answer: There are 360360 ways to appoint the members of the cabinet.

Step-by-step explanation:

Since we have given that

Number of eligible candidates = 15

Number of spots available = 5

We need to find the number of different ways the members can be appointed where rank matters

For this we will use "Permutations":

So, the required number of different ways in choosing the members for appointment is given by

^{15}P_5=360360

Hence, there are 360360 ways to appoint the members of the cabinet.

Andrea baked h muffins. violet baked 8 fewer muffins then andrea. find the average number of muffins baked by both girl, in term
Nana76 [90]
This is the concept of algebra, the average number of muffins baked by each girl will be given as follows;
Muffins baked by Andrea=h muffins
Muffins baked by Violet =h-8

Average=(Total sum of numbers)/(Number of items)
total sum=h+(h-8)=2h-8 
Number of items=2
thus;
average=(2h-8)/2=h-4
the answer in terms of h is (h-4)

Murljashka [212]
5x^2-22x-15=5x^2\underbrace{-25x+3x}_{-22x}-15\\\\=(5x^2-25x)+(3x-15)=5x(x-5)+3(x-5)\\\\=\boxed{(x-5)(5x+3)}
