I can't see D.

but really all you have to do is plug in the given coordinate into the equations to see which one works

in other words, since we are given (2,1)
we can go through each answer and plug in 2 for x to see if we get 1 as a result

by doing this, we see that only B correlates with this coordinate

How do you do this and what is the correct answer? Simple and concise explanation please!
abruzzese [7]

Answer:

Step-by-step explanation:

  • This is a neat question. I suggest that you graph it on desmos. You will lean a bunch by doing it. These are the graphs you should put on there.
  • y = 1/(abs(x - a) - 1):In red
  • When you use your down arrow, a new entry will be given you. You can use your mouse to operate the slider you get when you type a = 5
  • so your next graph should be a = 5
  • Use your down arrow again. Put in x = 4: Blue Line
  • Use your down arrow again. Put in x = 6: Green Line

Be patient with this. Play with the sliders to see what they do. I believe you are correct, but I am not certain of the second union although it does look correct.

The graph I have enclosed is of what I have described in the steps above. Make sure you try it all out.

If 120 marks is 60% what is full marks
AveGali [126]
Let's say is "x", so, then "x" is the 100%, and we know that the 60% is 120, what the dickens is "x" anyway?

\bf \begin{array}{ccll}&#10;marks&\%\\&#10;\text{\textemdash\textemdash\textemdash}&\text{\textemdash\textemdash\textemdash}\\&#10;x&100\\&#10;120&60&#10;\end{array}\implies \cfrac{x}{120}=\cfrac{100}{60}\implies x=\cfrac{120\cdot 100}{60}
