Answer:
Addition Property of Equality
Step-by-step explanation:
Given expression:
To find the missing justification.
We will evaluate the given expression and justify the step.
Using Addition Property of Equality( by this property of equality we can add a number to both sides of the equation without effecting the equality of the equation)
Adding to both sides of the equation.
The description of the corresponding partition is given as follows:
The infinite classes can be defined as:
At equal distance of x from point [1,2]
Where x can vary from o to infinity.
<h3>What is a corresponding partition?</h3>
The analogous partition, commonly known as "the set of equivalence classes," is the set A/R, the elements of which are the subsets of A satisfying the following:
For every a∈A there is some B∈A/R such that a∈B.
