Which property justifies this statement? if 12=x+5, then x+5=12. addition property of equality symmetric property of equality subtraction property of equality reflexive property of equality

Option 2 - Symmetric Property of Equality

Step-by-step explanation:

Given : If , then

To find : Which property justifies this statement?

Solution :

According to question,

If , then

Which is the property of symmetric.

Symmetric property of Equality states that if one value is equal to second value then second value is equal to first value.

i.e. If then

Therefore, The property justify the statement is Symmetric Property of Equality.

So, Option 2 is correct.

y = 2x

step-by-step explanation:

if you divide each number in the sequence, you'll see that they all have a multiple factor of 2. each number in the series, and any other numbers which may continue, will be multiplied by 2. therefore, y is the next number in the sequence, and x is the current one, so, our formula will be y = 2x.

answer:   b

step-by-step explanation:

x2 = 16

x can not be a negative number because 16 is positive

the only answer would be positive 8
