Problem: Find the value(s) of \(b\) that make(s) the following piecewise-defined function continuous for all real numbers. If there is no such value of \(b\), explain why.\[
      f(x) =
      \begin{cases}
        |2x-13|& \text{ $x\leq-5$} \\
        \\
        \dfrac{bx}{{x+7}} & \text{ $x>-5$} \\
                                       
      \end{cases}
    \]

\(b=-\dfrac{46}{5}\)
