A fish is swimming at a constant rate toward the ocean floor. The equation y = −7x − 3 can be used to represent this situation, where y is the depth of the fish in meters below sea level and x is the number of seconds the fish has been swimming. Which statement best describes the depth of the fish, given this equation?
From a starting position of 7 meters below sea level, the fish is descending 3 meters per second.
B From a starting position of 7 meters below sea level, the fish is ascending 3 meters per second.
C From a starting position of 3 meters below sea level, the fish is descending 7 meters per second.
D From a starting position of 3 meters below sea level, the fish is ascending 7 meters per second.
Please help quickly, Thanks!
C
think about it...
To determine the depth of the fish, you need to analyze the equation y = -7x - 3. In this equation, y represents the depth of the fish in meters below sea level, and x represents the number of seconds the fish has been swimming.
First, let's consider the coefficient of the x-term, which is -7. This means that for every second the fish swims, its depth decreases by 7 meters. The negative sign indicates that the fish is descending.
Next, let's consider the constant term, which is -3. This indicates that when the fish starts swimming (x = 0), its initial depth is 3 meters below sea level.
Combining these observations, we can conclude that the correct statement is:
A) From a starting position of 7 meters below sea level, the fish is descending 3 meters per second.
Therefore, the depth of the fish is decreasing by 3 meters per second, starting at a depth of 7 meters below sea level.
A pilot takes a taxi from the airport to a hotel. The taxi driver charges a 2.50 initial charge plus 2.65 per mile. Which equation can be used to find y, the total cost of the trip, if x represents the number of miles of the trip?
A. y=2.50x+2.65
B. y=2.65 (x+2.50)
C. y=2.65x-2.50
D. y=2.65x + 2.50

Lawrence’s father gave him 200 baseball cards. Each week, Lawrence purchases 25 baseball cards to add to his collection.
Which inequality can be used to find w, the number of weeks after starting his collection when Lawrence will have more than 750 baseball cards in his collection?
I’m dumb asf 👁👄👁
A fish is swimming from the water surface down at a constant rate of -3 feet per second.
A) At what depth would the fish be after 7 seconds?
B) How many seconds would it take the fish to reach a depth of -33 feet?
