3x+y=9.....i
3x-5y=15...ii
subtracting ii from i we get
6y=-6 so y=-1
x=10/3
Answer:
1
Step-by-step explanation:
use PEMDAS=
2+6=12
12x2=24
48/24=2
2-1= 1

Answer:
C
Step-by-step explanation:
A piece wise function involves two or more functions over specific intervals. The equations of the two lines are the following y=x+1 and y=-x+2.
