The independent variable (x) is the domain
Answer:
x=1/3
Step-by-step explanation:
You have to isolate the variable, so you must first separate the constants from the variable. Add 3 on both sides to cancel out the minus three and to move it to the other side. Now you have 27x=9. It's pretty simple from there just use your calculator and divide 27x/27 and also 9/27. That leaves you with 1/3

the number of protons identifies what element it is, since it has 35 protons it is Bromine
number of protons=atomic number
<span>You could set up the relation as a table of
ordered pairs. Then, test to see if each element in the domain is
matched with exactly one element in the range. If so, you have a function!</span>
