Question

Solve, write your answer in interval notation and graph the solution set.

2c. |6x+5| greater than or euqal to -5

2d. |3x| less than -1

Answer 1

2c. |6x+5| greater than or equal to -5
we know that |t|>=0>-5 for every t so|6x+5|>0>-5 for every x graph : real line (-infinity; infinity)
2d. |3x| less than -1
we know that |t|>=0 for every t so |3x| can't be lessthen 0 and then -1 so solution is empty set graph : empty set
