4x+3y=12
2x+3y=-6
which statements are true about the solution to the equations?
select each correct
a: the y coordinate of the solution is 9
b: the e coordinate of the solution is 9
c: the ordered pair that is the solution to the system lies and quadrant iv
d: the x coordinate of the solution is 8
e: the ordered pair that is the solution to the system lies in quadrant l
f: the y coordinate of the solution is -8

B, C, F

Step-by-step explanation:

Given:

Subtract the second equation from the first equation:

Option B "The x coordinate of the solution is 9" is ture

Substitute it into the first equation:

Option F "The y coordinate of the solution is -8" is true.

Point (9,-8) is in the IV quadrant, so option C is true.

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
