<h3>Given</h3>
... 4 - |2x -1| = -3
<h3>Find</h3>
... x
<h3>Solution</h3>
Add |2x-1|+3
... 7 = |2x-1|
This resolves to two equations:
... -7 = 2x-1
... -6 = 2x
... -3 = x
and ...
... 7 = 2x -1
... 8 = 2x
... 4 = x
The two solutions are x = -3 and x = 4.
I think they all went to the movies equally per month if you simply compare medians? Since in the second chart, they each have a median of 2 times per month, that makes it equal. If you aren’t sure if this is correct, you have to order how many times each person went to the movies, from least to greatest. For example, John’s would be 1,1,1,2,2,2,2,3,3,3,4,5. Then you would start crossing numbers off from each end. First you would cross off 1, then 5, and then 1, and then 4, and keep going until you reach the number in the very middle, which is 2. Do this with all of the other people, and check if everybody has 2 for a median. I believe they do, however it’s always best to check and be safe. Good luck
Answer:
Step-by-step explanation:
f(x) is like y in a linear equation. There is one major difference. F(x) tells you what to substitute on the right every time you see an x.
f(a) = -3a + 7
f(b) = -3b + 7
For this question a and b have values. Now work with the right side only. This is the quickest way to get the answer, but it is only marginally correct.
f(a) = -3(-8) + 7 = 24 + 7 = 31
f(b) = -3(7) + 7 = -21 + 7 = - 14
f(a) + f(b) = 31 - 14 = 17
f(a) - f(b) = 31 - (-14) = 31 + 14 = 45
Quite a vague question, I used desmos to graph the attached photo.
