$[3,6)$. The graph is shown below.

Work Step by Step

The given inequality is $\Rightarrow -3\leq\frac{2x}{3}-5\lt-1$ Multiply the inequality by $3$. $\Rightarrow -9\leq2x-15\lt-3$ Add $15$ to the inequality. $\Rightarrow -9+15\leq2x-15+15\lt-3+15$ Add like terms. $\Rightarrow 6\leq2x\lt12$ Divide the inequality by $2$. $\Rightarrow 3\leq x\lt 6$ The interval notation is $[3,6)$.
