If a pipe is to be cut to a length of 9 meters accurate to within three tenths of its diameter the relationship between the length x of the pipe and its diameter y satisfies which inequality?

l x - 9 l ≤ 0.3y

Step-by-step explanation:

Let x is the length of the pipe

Let y is the length of the diameter

Given that:

So we have the inequality that model this situation is:

l x - 9 l ≤ 0.3y

Hope it will find you well.
