Chapter R.1, Problem 23PE

Determine whether the statement makes sense or does not make sense, and explain your reasoning. I prefer interval notation over set-builder notation because it takes less space to write solution sets.

Express the set -3x + 21≤ 4x + 7 using the interval notation.

Please tell me if i write it in interval or set

Graph the set {x |x<-5} on the number line. Then, write the set using interval notation. {x]x s -5} = 0 (□,0) [□,미 (O,미 [□.미) 00 -7 -6 -5 -4 -3 -2 -1 3 4 5 6. 7 -00 ?
