QuestionSolve $10|7 x+7|+10 \geq 80$ for $x$.

Studdy Solution
Divide both sides of the inequality by -7. Remember that when you divide or multiply an inequality by a negative number, the direction of the inequality sign changes.
$$x \leq -\frac{15}{7}$$So, the solution to the inequality $10|7x +7| +10 \geq80$ is $x \geq \frac{}{7}$ or $x \leq -\frac{15}{7}$.
