Q. Solve for qq.q+82|q + 8| \leq 2Write a compound inequality like 1<x<31 < x < 3 or like x<1x < 1 or x>3x > 3. Use integers, proper fractions, or improper fractions in simplest form.\newline______
  1. Absolute Value Definition: We have the inequality q+82|q + 8| \leq 2. To solve for qq, we need to consider the definition of absolute value, which states that x=x|x| = x if x0x \geq 0 and x=x|x| = -x if x < 0. Therefore, the inequality q+82|q + 8| \leq 2 means that q+8q + 8 is at most 22 units away from 00 on the number line, in either direction.
  2. Non-Negative Case: First, we consider the case where q+8q + 8 is non-negative. In this case, we can drop the absolute value without changing the sign:\newlineq+82q + 8 \leq 2\newlineNow, we solve for qq by subtracting 88 from both sides:\newlineq+8828q + 8 - 8 \leq 2 - 8\newlineq6q \leq -6
  3. Negative Case: Next, we consider the case where q+8q + 8 is negative. In this case, we must change the sign when we remove the absolute value:\newline(q+8)2-(q + 8) \leq 2\newlineNow, we distribute the negative sign and solve for qq:\newlineq82-q - 8 \leq 2\newlineq2+8-q \leq 2 + 8\newlineq10q \geq -10 (after multiplying both sides by 1-1, we must reverse the inequality sign)
  4. Compound Inequality: Combining both cases, we have a compound inequality that represents all possible values of qq that satisfy the original inequality:\newline10q6-10 \leq q \leq -6\newlineThis compound inequality includes both the case where q+8q + 8 is non-negative and the case where q+8q + 8 is negative.
