Question

solve the inequality of solve the inequality of /x-800/≤80

Answer 1

|x-800|<=80
-80<=x-800<=80
x is in [720,880]

Answer 2

whenever you have an absolute value inequality like the one you have, you need to solve these two inequalities:

x-800 <= 80 AND x-800 >=-80

Answer 3

notice the two inequalities are joined by the conjunction AND. this will determine your solutions set to your inequality

Answer 4

can you solve the first inequality:
x-800 <= 80

Answer 5

i got it thanks
