The coordinates of the vertices of a triangle are L (3,2), M (5,7), and N (8,4). Triangle LMN is reflected across the x-axis
to create triangle L'M'N'. Which rule describes this
transformation?

30 miles

step-by-step explanation:

we know that 60 seconds equals 1 minute and 60 minutes 1 hour

44 ft       60 sec     60 min     158400   ft

  *   *   =

1 sec       1 min       1 hour         hour

we know that there are 5280 ft per mile

158400   ft       1 mile         30 miles

  *   =

1   hour               5280 ft     1 hour

so in 1 hour   it can travel 30 miles

answer: y=0 if that is what u r looking for
