Alarge ice floe is floating at a speed of 3 kilometers per hour. a polar bear leaves the floe and swims in the opposite direction at 9 kilometers per hour. how long will it be before the polar bear is 4 kilometers away from the floe?
how do i do my teacher never teaches

d

step-by-step explanation:

by observation, we can see that the the graph is simply the graph of y = |x| that has been shifted 4 units downwards and 3 units to the left.

we can recognize in choice d :

y = | x + 3 |   - 4 (rewriting in general form)

y = | x - (- 3) |   - 4

the "-4 " term means   that the graph has been shifted by 4 units in the negative y direction

the "-3 " term means   that the graph has been shifted by 3 units in the negative x direction

this matches our observation of the graph described above.
