Sung drove to the mountains last weekend. there was heavy traffic on the way there, and the trip took 10 hours. when sung drove home, there was no traffic and the trip only took 7 hours. if his average rate was 18 miles per hour faster on the trip home, how far away does sung live from the mountains? do not do any rounding.

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.
