<u>Answer</u>:
Option 5: -4 ≤ 7x - 7 ≤ 4
<u>Step-by-step explanation:</u>
It is required to find which expression is equivalent to |7x-7| ≤ 4
So, at the beginning we should review the rules of absolute value inequalities.
1) If |x| ≤ a ⇒ -a ≤ x ≤ a
2) If |x| < a ⇒ -a < x < a
3) If |x| ≥ a ⇒ x ≤ -a or x ≥ a
4) If |x| > a ⇒ x < -a or x > a
Applying the first rule to the given absolute value inequality:
|7x-7| ≤ 4 ⇒ -4 ≤ 7x-7 ≤ 4
So, the answer is option 5
we are rounding to the tenths place so we need to look at the hundredths place 5 and higher it goes up 4 and below it remains the same
15.50 thru 15.54 would round to 15.5
15.45 to 15.49 would round to 15.5
so 15.51 rounds to 15.5
15.49 rounds to 15.5
15.48 rounds to 15.5
