You got 9 right, because 5x -3y = 36
For you to lose points, having answered all of thee questions, to the point of which you were given 36 out of 60 possible points tells that you must have gotten over half right for points to have been taken away, and the only factors that satisfy the equation with those restrictions would determine that x must equal 9, making the amount you got right worth 45 points, but with y equal to 3, 9 points were taken away from that score, making it 36. This can also be displayed on a x versus y graph.

the answer is nine because 9times 5 equals 45 subtract 9 equals 36

Answer:

  • 6 units left and 4 up (if figure K translated)
  • 6 units right and 4 units down (if figure J translated)

Step-by-step explanation:

<em>It is not clear which of the figures is translated.</em>

<em>Assume it is figure K.</em>

Use one of the points and compare the corresponding point.

<u>If you take bottom-left point, then the difference is coordinates is:</u>

  • -7 - (-1) = -6, this is translation left by 6 units (or right if the figure J is translated)
  • 2 - (-2) = 4, this is translation up by 4 units (or down if the figure J is translated)

<u>So the answer is </u>

  • 6 units left and 4 up or, (figure K translated)
  • 6 units right and 4 units down (figure J translated)
