Part B.

Given the inequality:


7x-3(4x-8)\leq6x+12-9x

Given that the solution to part a is a number in the interval [4, 8], let's state all inetgers that satisfy the given inequality.

Here, we have the interval:

[4, 8]

After solving the inequality, we have the solution:


x\ge6

The interval [4, 8] means all numbers from 4 to 8.

Therefore, all numbers in this interval are:

4, 5, 6, 7, 8.

But for this solution we have that x is greater than or equal to 6.

This means it will be 6 or greater but less than 9.

Therefore, the integers that satisfy the given inequality are:

6, 7, 8

ANSWER:

6, 7, 8
