Question

After you have your answer(s), you should always:
Select one:
a. Graph the solution(s)
b. Take the cube root of the solution(s)
c. Substitute the solution(s) into the equation to check if the statement is true
d. None of the above

Answer 1

c

Answer 2

are you sure

Answer 3

100% sure. Use deduction. You can't always graph a solution and also graphing solution is sometimes not practical neither does it help when trying to check an answer.
Taking the cube root of a solution almost 99% of the time is pretty useless when checking a solution.
c) Think about it.
example
5=2x+1 Solve for x
x=2
Try substituting answer back into equation
5 = 2(2) +1
Is the answer 5? yes it is therefore x does = 2
