What happens if an absolute value equation is set equal to a negative number?

• There are two solutions

• There is one solution

• There are no solutions

When solving absolute value inequalities, what does it mean if the inequality is 'less than'?

• There is no solution

• The solution is above the graph

• The solution is inside the interval

• The solution is outside the interval

For the inequality |5 - x| > 3, what is the solution set?

• x < 2 and x > 8

• x < 2 or x > 8

• x > 2 and x < 8

• x = 2 or x = 8

What is the first step in solving an absolute value inequality?

• Set the inequality to zero

• Isolate the absolute value expression

• Graph the function
