Question

I need to answer this question then find the matching graph

Answer 1

we have

`\begin{gathered} 5a-2\ge8 \\ \text{solve for a} \\ 5a\ge8+2 \\ 5a\ge10 \\ a\ge2 \end{gathered}`

the solution is the interval {2, infinite)

In a number line the solution is the shaded area at right of a=2 (close circle)

therefore

the answer is

First option
