The inequality is -3x <= -54. We can solve it by dividing both sides by -3, making sure to reverse the inequality sign since we are dividing by a negative number:
x >= (-54)/(-3)
Simplifying the right side:
x >= 18
To graph the solution set, we need to plot all the values of x that satisfy the inequality. Since x is greater than or equal to 18, we can represent this on a number line by shading the region to the right of 18 and including 18 itself.
The solution set in interval notation is [18, +∞).
Solve the inequality. Graph the solution set and write it in interval notation.
