Answer:

I believe the answer is B,

explanation:

Well, the others are exactly alike, the first answer is just the two numbers flipped, the third is where multiplication is needed, so (2 x m^3) + (2 x 2) = 2m^3 + 4. and the final one is m^3 plus itself which equals to 2m^3 + 4.

Rewrite in mathematical language. Every negative integer J is less than or equal to its inverse.

Luda [366]

Answer:

$-J \leq J$

Step-by-step explanation:

Given

Negative integer J

Required

Represent as an inequality of its inverse

The question didn't state if it's additive inverse or multiplicative inverse;

Since the question has to do with negation, I'll assume it's an additive inverse

The inverse of -J is +J

To represent as an inequality (less than or equal), we have:

$-J \leq +J$

Solving further, it gives

$-J \leq J$
