Answer with explanation:
⇒The Meaning of Additive Identity is that element in a set when added to any member or elements of set yields that element.
Consider a system of forces under a set F , which is a vector space under a field .
The set F having three forces a, b, c will be a vector space if,
1.→ a +(b+c)=(a+b)+c
2.→ a+b=b+a
3.→There must exist a force equal to 0, such that when any of the forces added to 0 the resultant is force itself.
That is , a+0=a=0+a
→→So,If you consider any vector space over a field ,there exist an element in that set equal to 0, when added to any member of the elements of the set the result being that element.So, element 0 is the Additive Identity of any vector space.
Answer:
the original number is greater
Step-by-step explanation:
1. let 1x be your starting number
2. therefore, 0.5 * 1x = 0.5x ( amount after you decreased it by 50%)
3. then increase: 0.5x * 1.5 = 0.75x (amount after you increased it by 50%)
4. 0.75x < 1x (this means that the original number is larger than the one you decreased and then increased)
