Square root both sides
we get x-3=±√7
so that would be B
In algebra, the "domain" of a relation is the set of unique and acceptable INPUT values to the function. In typing out a domain, you'd eliminate any duplicates:
{1, 2, 2, 3, 4, 5, 7} (wrong, because 2 shows up twice)
and you'd ensure that the function/relation is defined at each INPUT value.
Note that the function y = sqrt(x) has domain [0, infinity), so negative numbers are not part of the domain; they are not acceptable input values.
Answer:
<em><u>Answer is below</u></em>
Step-by-step explanation:
<u><em>3+5(2−3)−6</em></u>
<u><em>=3+(5)(−1)−6</em></u>
<u><em>=3+−5−6</em></u>
<u><em>=3+−11</em></u>
<u><em>=−8</em></u>
<u><em>So therefore, your answer would be -8</em></u>
X=7
So...
7+6=13
Hope this helps!
