Question

The number line above shows the solution graph of which inequalit?

Answer 1

We are given a number line graph equivalent to the numbers of the line that are smaller than 8, where 8 is not included since in the graph it is shown with a hollow circle. Therefore, the inequality that represents this graph is the following:

`x<8`

we may multiply both sides by 2 and we get:

`2x<16`

Now we can add 9 on both sides:

`\begin{gathered} 2x+9<16+9 \\ 2x+9<25 \end{gathered}`

Therefore, the graph is the solution to inequality B
