Solve the inequality \(\displaystyle 6 \leq 1 - 5 x < 22\). Write the solution in interval notation.
Since this is a three part inequality we must do the same thing to all three parts.Subtracting 1 from all three parts gives \(\displaystyle 5 \leq 1 - 5 x < 21 \). Dividing off the coefficient of \(\displaystyle x\) gives and reversing all of the inequalies \(\displaystyle -1 \geq x > - \frac{21}{5}\)The solution is \(\displaystyle \big(- \frac{21}{5},-1\big]\)
