Question

This is compound inequality in Algebra II. I was wondering did I do this problem correctly.
- 4 ≤ 3+7x<24
= - 4 -3 ≤ 3 – 3+7x<24-3
= -7 ≤ 7x < 21
= -7 ≤ 7x< 21
7 7 7
= -1 ≤ x < 3

Answer 1

Yes mam it look s really good,

Answer 2

Thank you, How would I line graph this? <-----[-1--0----3]--->?

Answer 3

well a greater then or equal to has a closed dot over -1 and the just less then would have an open dot over 3 the line would be inbetween these.
