1 5/100 I think idk I hope I helped
Answer:
Step-by-step explanation:
Part A: make slope-intercept form of equation
We will have variable y for the depth of the submarine after x hours. The start 1,500 will be written -1,500 because it's below surface of water.
The equation after x hours will be
y = -1,500 + 52x
y = 52x - 1,500
Part B: Find the depth after two hours
Change variable x with 2
y = 52x - 1,500
y = 52(2) - 1,500
y = 104 - 1,500
y = -1,396
Negative means it's below surface
