Given the inequality.
t + 31 <2
Determine the minimum and maximum values.
Solution:
In order to solve for the minimum and maximum values, transpose first 31 on the other side of the equation, note that when transposing a number, the sign changes.
t < 2 - 31
t < -29
Th value is less than -29, in order to get the maximum value, multiply both sides by negative, hence when multiplying a negative in inequality, the inequality sign changes.
t > 29
Final answer:
t < -29
t > 29
