If j = k, then j + 9 = k + 9 represents which algebraic property
sleet_krkn [62]

Answer:

c) The given  expression represents Addition Property of Equality.

Step-by-step explanation:

Here, the given expression is j = k

Now by ADDITION PROPERTY OF EQUALITY:

The property that states that if you add the same number to both sides of an equation, the sides remain equal.

So,  <u>  if A  = B  ⇒  A + </u><u>x </u><u> =  B + </u><u>x</u>

<u></u>

Now, here given that j = k

If we add the same number 9 on both the sides, the equation remains  undisturbed.

⇒   j + 9  = k + 9

Hence, the above expression represents Addition Property of Equality.
