Hmmm I think either D or C
Answer:
XZ = 12x + 6
Step-by-step explanation:
XZ = XY + YZ
XZ = <u>4x</u> + 7 + <u>8x</u> - 1
XZ = 12x + 6
15/y+11-10/y+3=0
15/y-10/y=5/y 11+3=14
5/y+14=0
o-14=-14
5/y=-14
y=-5/14
The correct answer is letter D, Region D contains the solution for the system of inequalities.
