Ascuba diver is 3.8 meters below the surface of the water. he is descending at a rate of 0.5 meters per minute. part 1: write an algebraic expression to describe the depth of the scuba diver after any number of minutes. part 2: describe what the variable represents in this situation.

Step-by-step explanation:

A scuba diver is 3.8 meters below the surface of the water.

So, Depth of scuba driver is - 3.8 m

He is descending at a rate of 0.5 meters per minute.

So, Rate = -0.5 m . min

So,Distance traveled in x minutes = -0.05 x

So, The depth after x minutes = -3.8-0.5x

So, an algebraic expression to describe the depth of the scuba diver after any number of minutes is  -3.8-0.5x

The variable x represents the no. of minutes .
