a. x+0=xb. x+1=1+xc x+1+(-1)=xd (x)(1/x)=1i think its C. because its the best that fits, but can u kinda explain
it is C.. the additive inverse is just adding the opposite of a number.
A is the Additive Identity (you can add 0 to anything to get the same number back) B is the Commutative Property (you can add or multiply in any order) C I guess this would be the additive inverse because you are adding a number and then adding the negative of that number (which is what subtraction really is). D is the Multiplicative Identity (if you multiply something by its reciprocal you get 1)
Answer: C In mathematics, the additive inverse, or opposite, of a number x is the number that, when added to x, yields zero. The additive inverse of X is denoted ?X. For example, the additive inverse of 7 is ?7, because 7 + (?7) = 0, and the additive inverse of ?0.3 is 0.3, because ?0.3 + 0.3 = 0. In other words, the additive inverse of a number is the number's negative. For example, the additive inverse of 8 is ?8, the additive inverse of 10002 is ?10002 and the additive inverse of x? is ?(x?). The additive inverse of a number is defined as its inverse element under the binary operation of addition. It can be calculated using multiplication by ?1; that is, ?n = ?1 × n.
Your instincts and logic are quite right! Trust yourself, you do good work!
