Answer:
1:20
Step-by-step explanation:
Imagine taking 15 minutes off of 55 minutes, that will make it 40 minutes. So you are at 2:00 right now. Subtract the remaining 40 minutes and you will get 1:20
Use format y = mx + b
-15x + 5y = 20
-15x + 15x + 5y = 20 + 15x
5y = 20 + 15x
y = (20 + 15x)/5
y = 4 + 3x
y = 3x + 4
m is the slope, so 3 is the answer
The answer is 8 but I’m not really sure tno

Answer:
D
Step-by-step explanation:
Hi there!
We're given the equation y=-75x-50, which represents a submarine DESCENDING towards the ocean floor, where y is the depth in feet, and x is the number of minutes the submarine is descending
Since the submarine is DESCENDING, we can immediately eliminate A and C, which talk about the submarine ASCENDING
That leaves B and D
Looking at the given equation, y=-75x-50, -75 is the slope, or rate of change, and -50 is the y intercept, or the "beginning" (where the equation will "start")
Therefore, the submarine will start at -50 feet, or 50 feet below sea level
As x is the number of minutes the submarine is descending, that means that if the submarine travels 1 minute, it will descend 75 feet (-75*1=-75), at 2 minutes, it'll descend 150 feet (-75*2=-150), and so on
So that means the submarine must be descending at a rate of 75 feet per minute
Therefore D is the correct answer
Hope this helps! Good luck on your assignment :)
