Choose the correct solution and graph for the inequality z+9< _ 6

It would be the first option.

Step-by-step explanation:

minus 9 from both sides to get a -3

A good trick I learned was which ever way the arrow is pointing (in this case left) is the way the line will go.

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
