Q. Solve for t.∣t+8∣≤4Write a compound inequality like 1<x<3 or like x<1 or x>3. Use integers, proper fractions, or improper fractions in simplest form. ______
Absolute Value Inequality: We have the inequality ∣t+8∣≤4. The absolute value inequality means that the expression inside the absolute value, t+8, can be either less than or equal to4 or greater than or equal to −4. We will split this into two separate inequalities to solve for t.
Case 1: Non-Negative Expression: First, let's consider the case where the expression inside the absolute value is non-negative: t+8≤4. To find the value of t, we subtract 8 from both sides of the inequality.t+8−8≤4−8t≤−4
Case 2: Non-Positive Expression: Now, let's consider the case where the expression inside the absolute value is non-positive: −(t+8)≤4. This is equivalent to −t−8≤4. To find the value of t, we first add 8 to both sides of the inequality.−t−8+8≤4+8−t≤12Multiplying both sides by −1 (and remembering to reverse the inequality sign because we are multiplying by a negative number), we get:t≥−12
Combining Inequalities: Combining the two inequalities we have found, we get the compound inequality:−12≤t≤−4This means that t must be greater than or equal to −12 and less than or equal to −4.
