4x was subtracted from both sides. Then, -8 was divided from both sides. Lastly, 1/2x was placed in front of -2.
Answer: y = 2x
Step-by-step explanation:
The equation of a straight line can be represented in the slope intercept form as
y = mx + c
Where
m = slope = (change in the value of y in the y axis) / (change in the value of x in the x axis)
The equation of the given line is
y = 2x - 8
Comparing with the slope intercept form, slope = 2
If two lines are parallel, it means that they have the same slope. Therefore, the slope of the line passing through (- 3,-6) is 2
To determine the intercept, we would substitute m = 2, x = - 3 and
y = - 6 into y = mx + c. It becomes
- 6 = 2 × - 3 + c
- 6 = - 6 + c
c = - 6 + 6 = 0
The equation becomes
y = 2x

Answer:
Only sequence A
Step-by-step explanation:
Hi,
Formula for distance is:
d = v·t, where v is the velocity (a constant value, measured in m/s), and t is time of movement, measured in s, seconds.
1 km = 1000 m, and 1 h = 3600 seconds, therefore:
v = 120 km/h = 120 000 / 3600 m/s = 33.33 m/s, so v = 33,33 m/s.
t = 24 seconds.
d = v·t = 33,33 m/s · 24 s = 100·24/3 = 800 m.
So, building is 800 meters long.
Have you understood the solution ?
