Here we multiply the 2nd eqation with -1 and then add both
and answer is
-6y=12

Answer:
128 miles
Step-by-step explanation:
The convict has a head start of ...
distance = speed × time
distance = (8 mi/h) × (14 h) = 112 mi
That distance is being closed at a rate that is the difference between the speeds, so ...
64 mi/h -8 mi/h = 56 mi/h
The time it takes the guards to catch the convict will be ...
time = distance/speed
time = (112 mi)/(56 mi/h) = 2 h
The guards and prisoner will be at a distance from the prison of ...
distance = speed × time
distance = (64 mi/h)(2 h) = 128 mi
The convict will be caught 128 miles from the prison.
__
<em>Check</em>
The convict will run an additional (8 mi/h)(2 h) = 16 mi after the guards start pursuit. That, in addition to the 112 miles already run, will total 112+16=128 miles, the same distance the guards travel in that 2 hours.
Answer:
Variant A
Step-by-step explanation:
1)y= - 3x+1
2)y+5= - 3(x-2)
y+5= - 3x+6
y= -3x+1
They are equal
3 9/10 + 4/5
39/10 + 4/5
39/10 + 8/10
47/10= 4 7/10
Answer:
slope = 0
Step-by-step explanation:
point1 = (0,7)
point 2 =(7,7)
slope = (y2-y1)/(x2-x1) => (7-7)/(7-0)
slope = 0
