Answer:
I got x <= 8/7 which is none of the answer options given. Ask your professor about that.
Step-by-step explanation:
7x-1 <= 7
add 1 on each side
7x <= 8
Divide by 7 on both sides
7x/7 <= 8/7
Final answer
x <= 8/7
Answer:
Option #1, 3 and 4
Step-by-step explanation:
7x - 1 <= 7
Let's try them one by one:
1)
x <= -1
-7 - 1 = -8 is less than or equal to 7: True
There could be multiple answers, so let's do the other ones:
2)
x <= 4
28 - 1 = 27 <= 7: False
3)
x <= 1
7 - 1 = 6 <= 7: True
4)
x >= -1
-7 - 1 <= 7
-8 <= 7: True
Therefore, #1, 3, and 4 are correct.
