Question

Which of the following graphs represents all values of such that 7x+4 < 9.r - 2 ?

Answer 1

`7x+4\leq9x-2`

To find the graph you solve the inequality, as follow:

`\begin{gathered} 7x+4\leq9x-2 \\ 7x-9x\leq-2-4 \\ -2x\leq-6 \\ \\ x\ge(-6)/(-2) \\ \\ x\ge3 \end{gathered}`

Then, the graph is:
