Question 657498
5x/ -5x+17 ≥ 17
In my book the answer is [289/90,17/5]
**
[5x/ (-5x+17)] ≥ 17
add -17 to both sides
[5x/ (-5x+17)]-17 ≥0
LCD: (-5x+17)
[5x-17(-5x+17)]/ (-5x+17)≥0
[5x+85x-289)]/ (-5x+17)≥0
[90x-289)]/ (-5x+17)≥0
[90(x-289/90)]/[-5(x-17/5)]≥0
number line:
<..-....[289/90....+....17/5]....-......>
solution:[289/90,17/5]
