I need help on this question

  C)  (x, y) ⇒ (x -3, y -4), (5, -1)

Step-by-step explanation:

You know that the x-coordinate measures how far to the right of the y-axis a point is. If the point is moved 3 units left, it will be 3 fewer units to the right of the y-axis. That is, its x-coordinate will have changed from x to x-3.

Similarly, moving a point down 4 units reduces its y-coordinate by 4 units, so that y becomes y-4.

Together, these transformations are ...

  (x, y) ⇒ (x -3, y -4) . . . . . . matches choice C

10.416 meters per second

step-by-step explanation:

distance=1 00 meters

time= 9.6 seconds in decimal form or 9 3/5 as a mixed number

average speed= 100/9.6

=10.416 meters per second or 10 52/125 as a mixed number.
