An object starts at position 12 on a horizontal line with a reference point of 0. what is the position of the object if it moves 14 units to the left? –26 –2 2 26

Answer;

–2  

Explanation;A reference point is a point required in order to determine whether or not an object moves. In this case; the position with reference to point 0 would be -2. This is because the starting position would be 12 units from the right of 0, assigning right direction to be positive. Assigning left of 0 point to be negative, when moving 14 units to the left, the object's final position is 2 units to the left of 0 or -2

therefore, the efficiency is:
