Solve the system. what restriction, if any, must be placed on the constants to make sure that there is a unique solution to the system? ax + y = b bx + y = a a) (1, a + b); a ≠ 0 b) (1, a - b); no restriction c) (−1, a + b); a ≠ b d) (−1, a - b); b ≠ 0

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.

plz mark brainliest i took the test
