9. For a class picnic, two teachers went to the same store to purchase drinks. One teacher purchased 9 juice boxes and 16 bottles of water and spent
$14.25. The other teacher purchased 3 juice boxes and 9 bottles of water and
spent $7.50. (6 points)
Write a system of equations to represent the scenarios mentioned above.
Let x = the cost of a juice box
Equation:
I
Equation:
Let y = the cost of a water
Kara said that the juice boxes might have cost $0.31 each and that the bottles
of water might have cost $0.73 cents each. Use your system of equations to
justify that Kara's prices are not possible. Check the point in the system.

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.

false

step-by-step explanation:

false.   two legs of the trapezoid would be congruent, but the other two would not.   were all the legs congruent, then we'd have a square; were the 2 shorter sides congruent and the 2 longer sides also congruent, we'd have a rectangle.
