Answer:
Amy is correct in her answer.
Step-by-step explanation:
Here, the given expression is:
5X - 2 ≤ 18
The answer quoted by Amy = X ≤ -6
⇒ Possible values of X = -6, -7, -8, -9, -10,...
The answer quoted by Bryan = X ≥ -6
⇒ Possible values of X = -6, -5, -4, -3, -2, ...., 4, 5, 6, 7..
Now, simplifying the given inequality,
5X - 2 ≤ 18 ⇒ 5X - 2 + 2 ≤ 18 + 2
or, 5X ≤ 20
or, X ≤ 20/5 = 4
⇒ X ≤ 4
Hence, the possible values of X = 4, 3, 2, 1, 0, -1, -2, .....
So, from above answers, X ≤ -6 is the most appropriate answer
as here,all possible values of x are less than 4.
Hence, Amy is correct in her answer.
