Absolute Value of −t: We have the inequality: ∣−t∣≥3First, we solve for ∣−t∣.∣−t∣ is the absolute value of −t, which means it is the distance of −t from 0 on the number line. The absolute value of a number is always non-negative, so ∣−t∣ can be either t or −t, depending on the sign of t.
Splitting into Two Inequalities: Since ∣−t∣)representsthedistancefrom$0, it can be split into two separate inequalities:−t≥3 or t≥3However, since we have −t in the first inequality, we need to multiply both sides by −1 to solve for t. Remember that multiplying or dividing an inequality by a negative number reverses the inequality sign.
Solving for t: Multiplying the first inequality by −1 gives us:t≤−3So now we have two inequalities:t≤−3 or t≥3This is the compound inequality that represents the solution to the original problem.
