Question
Solve each compound inequality. Graph the solution set and write it using interval notation.$$2(x+2)<x-11 \text { or }-\frac{x}{5}<20$$
Step 1
For the first inequality, we distribute the 2 on the left side to get $2x+4<x-11$. Then, we subtract $2x$ from both sides to get $4<-x-11$. Adding 11 to both sides gives us $15<-x$, or equivalently, $x<-15$. Show more…
