Answer:

6% of the changes were from incorrect to​ incorrect

Step-by-step explanation:

The sum of the percentages must be 100%.

We have these following percentages

65​% of the changes were from incorrect answers to correct

29​% were from correct to incorrect

P% were from incorrect to incorrect

So

65 + 29 + P = 100

P = 100 - 94

P = 6

6% of the changes were from incorrect to​ incorrect

Answer:

  D. The graph of g(x) is the graph of fix) translated to the left 7 units and up 9 units

Step-by-step explanation:

The transformation of f(x) to g(x) ...

  g(x) = a·f(b·x -c) +d

involves ...

  • vertical expansion by a factor of "a"
  • horizontal compression by a factor of "b"
  • translation to the right by "c" units
  • translation up by "d" units

Here, you have a=b=1, c=-7, d=9, so the graph of f is translated left 7 units and up 9 units to make the graph of g.
