Solve $LaTeX: \displaystyle 5 - 9 x \leq 5$ . Write the solution in interval notation.

Isolating $LaTeX: \displaystyle x$ gives $LaTeX: \displaystyle - 9 x\leq0$ . Dividing off the $LaTeX: \displaystyle x$ coefficient and reversing the inequality symbol because its negative gives $LaTeX: \displaystyle x\geq0$ . The solution is $LaTeX: \displaystyle \left[0, \infty\right)$
