Solve for b.∣b∣−7≤7Write a compound inequality like 1 < x < 3 or like x < 1 or x > 3. Use integers, proper fractions, or improper fractions in simplest form.______
Q. Solve for b.∣b∣−7≤7Write a compound inequality like 1<x<3 or like x<1 or x>3. Use integers, proper fractions, or improper fractions in simplest form.______
Isolate absolute value: First, we need to isolate the absolute value expression on one side of the inequality.∣b∣−7≤7Add 7 to both sides to isolate the absolute value.∣b∣−7+7≤7+7∣b∣≤14
Consider absolute value definition: Now we need to consider the definition of absolute value, which states that |b|\(\newline) is the distance of b\(\newline) from \(0) on the number line. This means that b\(\newline) can be either positive or negative, but not farther than \(14) units away from \(0).So we have two cases:Case 1: b\(\newline) is non-negative, which gives us b \leq \(14).Case 2: b\(\newline) is negative, which gives us -b \leq \(14), or equivalently, b \geq \(-14) after multiplying both sides by \(-1) and reversing the inequality sign.
Combine cases into compound inequality: Combining both cases into a compound inequality, we get:−14≤b≤14This compound inequality represents all the values of b that satisfy the original inequality ∣b∣−7≤7.
