Answer:
y = 0.6x - 3.2
Step-by-step explanation:
Parallel lines have the same slope, so in this case the parallel line will be:
y = 0.6x + b
There's b because you don't know the y-intercept yet
Then you want to substitute the point (-3, -5) since the parallel line passes through it
-5 = 0.6(-3) + b
-5 = -1.8 + b
b = -3.2
*solved for y-intercept
Answer: y = 0.6x - 3.2
d1 = 51(t)
d2 = 71(8 - t)
d1 + d2 = 508
and now you just have to solve for t.
Sorry for all the scribbles if you dont get it just answer/reply back lol.
Answer:
The speed of the submarine is 5 mph
Step-by-step explanation:
Let x represent the speed of the submarine.
A submarine left Hawai'i 2 hours before an aircraft carrier. If the aircraft carrier travelled for 9 hours and after this time, the vessels were 280 miles apart, it means that submarine travelled for 9 + 2 = 11 hours and the total distance covered by submarine and the aircraft is 280 miles.
Distance = speed × time
Distance covered by the submarine would be
11 × x = 11x
The aircraft carrier traveled at 25 mph. Distance covered by the aircraft would be
25 × 9 = 225
Therefore,
225 + 11x = 280
11x = 280 - 225 = 55
x = 55/11 = 5mph
