Solve $LaTeX: \displaystyle 5 x - 9 \geq -2$ . Write the solution in interval notation.

Isolating $LaTeX: \displaystyle x$ gives $LaTeX: \displaystyle 5 x\geq7$ . Dividing off the $LaTeX: \displaystyle x$ coefficient gives $LaTeX: \displaystyle x\geq0$ . The solution is $LaTeX: \displaystyle \left[\frac{7}{5}, \infty\right)$
