What system represents line
2x+y=3
-2y=14-6

Hmm, try: - y=-2x+3  and - y=-7+3

Step-by-step explanation:

if that is not right then try: y= -2 x t -3  and Y= -2 x t -3

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
