Answer:
| x - 0 | ≤ 2
Step-by-step explanation:
Given,
The ideal temperature of the freezer = 0° F,
Also, it can fluctuate by 2° F,
Thus, if x represents the temperature of the freezer,
Then, there can be two cases,
Case 1 : x > 0,
⇒ x - 0 ≤ 2
Case 2 : If x < 0,
⇒ 0 - x ≤ 2,
⇒ -( x - 0 ) ≤ 2,
By combining the inequalities,
We get,
| x - 0 | ≤ 2,
Which is the required inequality.
We would need to know how many students are in the class to properly answer the question.
You should plug this into a graphing calculator on your computer! It helps a lot!
Answer:
(-3,12)
Step-by-step explanation:
The picnic area is 20 inches wide in the drawing in her scale of 1 inch : 4 yards.
<h3>What is unitary method ?</h3>
Unitary method is a technique for first solving the value of a single digit unit and from there we can find the value of any given unit.
According to the given question lillian drew a scale drawing of a county park. the scale she used was 1 inch : 4 yards.
The picnic area is 80 yards wide in real life.
∴ The width of the picnic area in here drawing in inches will be
= 80/4 inches.
= 20 inches.
