I'm not sure about answer...

2 and -2

Step-by-step explanation:

pretty much its asking when y = 4 what does x equal and if you look at the graph when y = 4 x = 2 and -2

54 km / hours

step-by-step explanation:

we need to convert seconds to hours

60 seconds = 1 minutes

60 minutes = 1hour

15 m         60 second   60 minutes

  * *         = 54000 meters/ hour

second     1 minute             1 hour

now we need to convert meters to km

1000 m = 1 km

54000 m       1 km

*   = 54 km / hours

hour               1000m

yes

step-by-step explanation:
