Inequalities are used to represent unequal expressions.
The solution of [tex]\mathbf{5 \le 9 - 4a}[/tex] is [tex]\mathbf{a \le 1}[/tex]
The expression is given as:
[tex]\mathbf{5 \le 9 - 4a}[/tex]
Subtract 9 from both sides
[tex]\mathbf{-4 \le - 4a}[/tex]
Divide both sides by -4
[tex]\mathbf{1 \ge a}[/tex]
Rewrite as:
[tex]\mathbf{a \le 1}[/tex]
See attachment for the graph of [tex]\mathbf{a \le 1}[/tex]
