Question

Choose the correct solution and graph for the inequality-5y<_-15

Answer 1

For this case we have the following inequality:

`-5y \leq-15`

To solve, we follow the steps below:

We divide between 5 on both sides of the inequality:

`-y \leq \frac {-15} {5}\\-y \leq-3`

We multiply by -1 on both sides taking into account that the sense of inequality changes:

`y \geq3`

Thus, the solution is given by all values of "y" greater than or equal to 3.

Answer:

`y \geq3`
