Question

PLEASE HELP ME FIND AND SOLVE THE INEQUALITY
`(b)/(3) \geqslant - 1`

Answer 1

we have

`(b)/(3)\ge-1`

Multiply by 3 both sides

`b\ge-3`

The solution for b is all real numbers greater than or equal to -3

{-3, infinite)

In a number line the solution is the shaded area at right of b=-3 (close circle)
