Answer:
[tex]r<-8[/tex]
Step-by-step explanation:
The given inequality is
[tex]-2r+3>19[/tex]
Notice that the inequality has only one variable, which means it has solution only in one axis.
Solving for [tex]r[/tex], we have
[tex]-2r+3>19\\-2r>19-3\\-2r>16\\r<\frac{16}{-2}\\ r<-8[/tex]
The solution is a set formed by all real numbers least than -8.
The image attached shows the graph of this solution.
