Solve for u.∣−7u∣≤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 u.∣−7u∣≤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.______
Identify Inequality: We have the inequality: ∣−7u∣≤7First, we solve for ∣−7u∣.∣−7u∣≤7This means that −7u is less than or equal to7 and greater than or equal to −7.
Split into Two: Now we split the inequality into two separate inequalities because the absolute value of a number is the distance from zero, and it can be either positive or negative.−7u≤7 and −7u≥−7
Solve for −7u: We solve the first inequality for u:−7u≤7To isolate u, we divide both sides by −7. Remember that dividing by a negative number reverses the inequality sign.u≥−1
Combine Inequalities: We solve the second inequality for u: −7u≥−7Again, we divide both sides by −7, and the inequality sign reverses.u≤1
Final Compound Inequality: Now we combine both inequalities to form the compound inequality: −1≤u≤1 This is the solution to the given problem.
