3. karen had 2 spools of wire. each spool had 15 7/8 yards of wire. karen used 3 yards of wire from each spool.
how many yards of wire were left on the spools?

15 7/8 + 15 7/8 = 31 6/8 or 31 3/4 

31 3/4 - 6 = 25 3/4 or 25 6/8

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.
