What is the solution set for x-4> 2?

(6,∞)

x > 6

Step-by-step explanation:

Solve by adding 4 to both sides.

To put this in interval notation for your solution set, consider your sign.

You have a greater than sign, which means that 6 is not a solution. In interval notation, that means that you should use parentheses " ( " instead of brackets " [ ".

Your solution set goes on infinitely, and infinity also uses parentheses rather than brackets.

You can write your solution set in interval notation as follows:

(6, ∞)

reduce the friction between its moving parts

step-by-step explanation:

in fact, by reducing the friction between the moving parts of the machine, it is possible to reduce the energy wasted due to this friction; therefore, more input energy is converted into useful work, and this will improve the efficiency of the machine.

answer: $201

step-by-step explanation: to get the answer, you first get 3 nieces that he sold and multiply it by 67 and get $201, so he earned $201 selling his nieces.
