<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
One bottle has a height of 12 centimeters or 12 cm. Let
us call this h1, so h1 = 12 cm
While the other bottle has a height of 15 centimeters or
15 cm. Let us call this h2, so h2 = 15 cm
The difference in height can be calculated by subtracting
the smaller number from the bigger number, therefore:
difference in height = h2 – h1
difference in height = 15 cm – 12 cm
difference in height = 3 cm
We know that in 1 meter there is:
1 meter = 100 centimeters = 1000 millimeters
Therefore,
difference in height = 3 cm (1000 millimeters / 100
centimeters)
difference in height = 30 mm
6(a-7)(a^2-2)
thats the answer for your quesion
Answer:
Landing on a 3.
Step-by-step explanation:
The probability of landing on a 3 is 3/8.
The probability of landing on a 5 is 1/8.
3/8 > 1/8
