A. by decreasing the amount of work you do on an object
To determine how a machine can make work easier for you, let's go through each option:
A. By decreasing the amount of work you do on an object: This is correct. Machines can reduce the amount of effort or force required to perform a task. For example, using a lever to lift a heavy object requires less force than lifting it directly with your muscles.
B. By changing the direction of your applied force: This is also correct. Machines can change the direction of your applied force, allowing you to exert force in a more convenient or efficient way. For instance, using a pulley system to lift objects can change the direction of your force from vertically downwards to horizontally sideways.
C. By increasing the work done by the machine: This is incorrect. Machines do not increase the work done; they simply enable you to accomplish the work with less effort.
D. None of the above: This is incorrect, as options A and B are valid ways in which machines can make work easier.
So, the correct answer is A, by decreasing the amount of work you do on an object, and B, by changing the direction of your applied force.
