Substitute each value for x into the absolute value equation to solve this problem. Start with A. x = 4/5.

|(4/5) + 3| = 4(4/5) - 7

Add 4/5 and 3 inside the absolute value symbols, and multiply 4 times 4/5 on the right side of the equation.

|19/5| = 16/5 - 7

Subtract 16/5 and 7.

|19/5| = -19/5, which is a false statement because the absolute value of 19/5 is 19/5, and 19/5 does not equal -19/5. This cancels out A from our possible solutions.

Now substitute B. x = 10/3 into the equation.

|(10/3) + 3| = 4(10/3) - 7

Add 10/3 and 3 inside the absolute values, and multiply 4 times 10/3 on the right side of the equation.

|19/3| = 40/3 - 7

Subtract 40/3 and 7.

|19/3| = 19/3, which is a true statement so we can include B in our possible solutions. Check the box B.

Substitute C. x = -4/5 into the equation.

|(-4/5) + 3| = 4(-4/5) - 7

Solve as you did the other ones; add inside the absolute values and multiply and subtract 7 from the answer on the right side of the equation. After doing this you will get: 2.2 = -10.2, which is a false statement so C will be eliminated from possible answer choices.

Substitute the last one; D. x = -10/3.

|(-10/3) + 3| = 4(-10/3) - 7

Solving this you will end up with: 0.3 = -20.3, which is a false statement so the only answer choice that is a possible solution is B.

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.

a 4/6 = 9/12   not proportional

step-by-step explanation:

to find which are not proportional, we can use cross products

if it is true, they are proportional.   if it is not true, they are not proportional.

a 4/6 = 9/12

4* 12 = 6*9

48 = 54

not this is not proportional  

b 2/3 = 12/18  

2* 18 = 3 * 12

36 = 36

this is proportional

c 5/4 = 10/8  

5*8 = 4*10

40 = 40

this is proportional

d 7/5 = 35/25

7*25 = 5 * 35

175 = 175

is proportional
