Hi, I’m not sure what steps to take to solve this. Aubrey and Fatima will each run 150m on the two inside lanes of the track, so the end markers need to be placed correctly. To the nearest hundredth, what are x and y?

Thank you

x= time recorded by Audrey

y=time recorded by Fatima

Step-by-step explanation:

The distance that Aubrey and Fatima travel is the same (constant 150m) and the markers are also the same, so the difference will be the times that the markers (variables) that each take to travel the same distance will record, therefore x and y represent the times recorded by Aubrey and Fatima

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.
