Two trains leave the station at the same time going in opposite directions. one of the trains travels at 90 mph and the other is traveling at 120 mph. after how many hours will they be 735 miles apart?

3.5

Step-by-step explanation:

210miles

735miles

divide 735/210= 3.5

trust the answer

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.
