Question

17. Match each example with the appropriate property.

Answer 1

Answer:

1. x+(-x)=0  matches D. Additive inverse (When you add at any number its inverse value, the result is allways 0 - zero- example : 3 + (-3) =3 -3 =0.
2. x+ 0 =x matches C. Additive identity (Zero is a neutral element in any sum, then, if you add zero to any number, the number remains the same, example: 3 + 0 =3)
3. (sorry, I understand that this expression may be not well copied)            x. (1/x)  = 1  matches B. multiplicative inverse (multiplicative inverse is that number that when multiply with our originalnumber,in this case x will give us the number 1 - example: the multiplicative inverse of 3 is $\frac{1}{3}$, because $3\frac{1}{3}=1$.
4. x . 1 = x matches A. Multiplicative identity (One is the neutral element of multiplication, thenif you multiply any number by 1, it remains the same, example: 3 . 1= 3)
