Math Problem Statement
Which statement about the ordered pairs (3, −8) and (4, 4) is true for the equation 3x−y4=11?
Responses
(4, 4) is a solution to the equation but not (3, −8). Begin ordered pair 4 comma 4 end orderd pair is a solution to the equation but not Begin ordered pair 3 comma negative 8 end ordered pair .
(3, −8) is a solution to the equation but not (4, 4). Begin ordered pair 3 comma negative 8 end ordered pair is a solution to the equation but not Begin ordered pair 4 comma 4 end ordered pair .
Both ordered pairs are solutions. Both ordered pairs are solutions.
Neither ordered pair is a solution.
Solution
We need to check whether each ordered pair satisfies the given equation:
For the first ordered pair :
Substitute and into the equation:
Since the equation holds true, is a solution.
For the second ordered pair :
Substitute and into the equation:
Since this equation also holds true, is a solution.
Conclusion:
Both ordered pairs are solutions. Thus, the correct response is:
Both ordered pairs are solutions.
