Either table c or table d shows a proportional relationship. plot all the points from the table that shows a proportional relationship. i'll post a picture of the graph. table c is ( x= 2,4,6,8) and y= ( 1,3,5,7). table d is ( x= 2,6,8,10) and y= ( 1,3,4,5).

Step-by-step explanation:

A proportional relationship is a straight line through the origin that grows at a constant rate

For table C

The constant of proportionality is y/x

2/1 = 4/3 = 6/5 = 8/7   This is not true so this is not proportional

For table D

The constant of proportionality is y/x

1/2 = 3/6 = 4/8 = 5/10   This is  true so this is  proportional

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.

step-by-step explanation:

you can add the two numbers and divide the result by 2. or you can find the gap between the two numbers and add half of this to the smaller number.
