Final answer:
The opposite of +5 is -5, which is represented by option (b). The integral opposite is the number with the same magnitude but a different sign.
Step-by-step explanation:
The question asks us to match each integer with its opposite. The opposite of any integer is the integer with the same magnitude but a different sign. For example, the opposite of +5 is -5.
Therefore, the correct match for the opposite of 5 is:
- (a) 5
- (b) -5
- (c) 10
- (d) None of the above
The answer is (b) -5. When dealing with opposites, it's important to remember that we are simply changing the sign of the number, not its magnitude.
So when the problem asks for the opposite of +5, we change the plus to a minus and get -5.
