Solve the inequality LaTeX:  \displaystyle 0 \leq - 4 x - 9 < 13 . Write the solution in interval notation.

Since this is a three part inequality we must do the same thing to all three parts.Adding 9 to all three parts gives LaTeX:  \displaystyle -9 \leq - 4 x - 9 < 4  . Dividing off the coefficient of LaTeX:  \displaystyle x gives and reversing all of the inequalies LaTeX:  \displaystyle \frac{9}{4} \geq x > -1 The solution is LaTeX:  \displaystyle \big(-1,\frac{9}{4}\big]
