Answer:
Subtraction property of inequality
Step-by-step explanation:
Step 1: Definition of Subtraction property
Subtraction property of equality refers to balancing an equation by using the same mathematical operation (minus) on both sides.
Step 2: Relate the definition above with the given question.
It can be seen from the statements in the question that 3 was subtracted from both sides of the initial equation to get:

I'm just going to give the answers snce so many questions
1. 2
2. 2/(m^2)
3. 1/(16x^8)
4. 3x^4
steps one: the one that starts with squareing both sides (√5x-9)^2=4^2)
23. x=9
24. 0
last graph one: third one (one that starts at 2 up from the origin)
