Ido not get how to write it in a number line

Step-by-step explanation:

Representing inequalities on number line:

First of all we write the inequalities that are to be represented.

Let x represent the elevation of the miner at any time of the day.

The minimum elevation is 6 ft below the sea level. If we consider the sea level as 0 on the number line, the lower limit is -6.

The maximum elevation is 6 ft above the sea level. Hence the upper limit is 6.

The elevation throughout the day is represented by the inequality:

-6 ≤ x ≤ 6 and represented on the line as shown in the picture attached.

Note: The solid end points of the line at 6 and -6 means that 6 and -6 are included in the inequalities.

step-by-step explanation:

a.   since the profit made in 2012 is equal to the profit made in 2014, the profit is           symmetric about the line y = 120,000.

step-by-step explanation:

given that megan owns a clothing boutique.

the profits of 2010, 11, are recorded and shown as follows:

years since     2010 0     1     2     3       4       5

profits made in 1000's   39       84     111     120   111     84

we find that profit gradually increases form 2010 to 2013 upto 120,   then starts decreasing.

the profits for 2012 and 2014 are the same while that of 2011 and 2015 are also the same.

this shows that there is symmetry about the line profit = 120000

hence answer is:

a.   since the profit made in 2012 is equal to the profit made in 2014, the profit is           symmetric about the line y = 120,000.
