Answer:
the solution is (-4, -3)
Step-by-step explanation:
Multiply the first equation by 2. This produces 4x + 2y = -14.
Now combine this result with the second equation:
4x + 2y = -14
-3x - 2y = 10
------------------
x = -4
Subbing -4 for x in the first equation yields 2x - 4 = -7, or 2x = -3.
Then x = -3/2, and the solution is (-4, -3)

Answer:
t=0.4 sec
Step-by-step explanation:
Remember that
1 mile=5,280 feet
1 hour=3,600 seconds
Let
s -----> the speed in ft/sec
d ----> the distance in ft
t -----> the time in sec
s=d/t
Solve for t
t=d/s
step 1
Convert miles/hour to ft/sec
105.1 mi/h=105.1(5,280/3,600)=154.15 ft/sec
step 2
Find the time
t=d/s
we have
s=154.15 ft/sec
d=60.5 ft
substitute
t=60.5/154.15
t=0.4 sec
Answer:
A: (-6, -3)
B: (-6 , -9)
