B/5>-1<br> Solve the inequality. Graph and check the solution.

Usimov [2.4K]

Answer:

b>-5

Step-by-step explanation:

$\frac{b}{5} > - 1$

Multiply by 5 to isolate b.

$b > - 5$

If you graph this on a line, it would be a hollow point facing the right, since it's any number greater than five, not including 5.

If you put any number greater than -5, you'll output greater than - 1.
