Which statement about the ordered pairs (−9, 3) and (2, −4) is true for the equation 6x−y2=14? 1. Neither ordered pair is a solution.

2. (−9, 3) is a solution to the equation.

3. Both ordered pairs are solutions.

4. (2, −4) is a solution to the equation.

Correct answer choice is:

C. A stopwatch

Explanation:

The best a decent eye will do is fix a reading to one tenth of a second, that is so the design of the stopwatch. The digital stopwatch has 2 digits on the far side the seconds, thus it further separates the time in hundredths of a second. Since it's simple to scan to hundredth of a second, that's its design.
