Question

3 On their first dive, researchers explore a part of the ocean floor that is 60 feetbelow sea level. This depth can be represented by the integer - 60. On theirsecond dive, researchers explore a deeper depth.Part AWrite an inequality that represents the possible depth, d, of the researchers'second dive.Answer:Part 8On the number line below, graph the inequality that represents the possibledepth of the researchers' second dive.A++ + ++++-150-120-90 -50 -30 0306090120150

Answer 1

we have that

The inequality that represents the possible depth, d, of the researcher's second dive is

d < -60

All real numbers less than -60

Part B

see the figure below

In a number line, the solution is the shaded area at the left of x=-60 (open circle)

the solution is the interval (-infinite, -60)
