Question

solve the inequality.
r + 4 < 5
the solution is .
graph the solution.

Explanation:

Step1: Isolate the variable r

Subtract 4 from both sides of the inequality $r + 4<5$.
$r+4 - 4<5 - 4$

Step2: Simplify the inequality

$r<1$

Answer:

$r < 1$; For the graph, you would use an open - circle at 1 (since 1 is not included in the solution) and an arrow pointing to the left on the number line.
