Question

Which graph is a solution set to the opening sentence? 10< -2b or 2b+3>11

Answer 1

`10 < -2b\qquad\text{change the signs}\\\\-10>2b\qquad\text{divide both sides by 2}\\\\-5>b\to \boxed{b<-5}\\\\2b+3>11\qquad\text{subtract 3 from both sides}\\\\2b>8\qquad\text{divide both sides by 2}\\\\\boxed{b>4}`

The second graph.
