Answer:
16 inches after one year
Step-by-step explanation:
in 3/4 a year tree grew 12 inches
divide by 3
multiply by 4
16 inches
Y = -6x + 2 . . . . . . . . (1)
-12x - 2y = -4 . . . . . . (2)
Putting (1) into (2), we have
-12x - 2(-6x + 2) = -4
-12x + 12x - 4 = -4
-4 = -4
Therefore, the system has infinite number of solutions.
