2x - 2y + 2z = 16
4x - y - z = -19
5x + y - 3z = -30

1. y=-x+z-8

2. y=-Z+4x+19

3. y=-5x+3z-30

the answer is c.

for continuous functions, they continue in the same pattern and you have to find that pattern kinda like slope

option 2 is correct.

step-by-step explanation:

we are given two inequality equation

x+y> 5 and -3x+2y< -2

first we draw the graph of both function using t-table method

equation: x+y> 5

for x=0, y=5

for x=-5, y=0

table:

x   :   0     5

y   :   5     0

test point (0,0) , 0> 5

false

equation: -3x+2y< -2

for x=0, y=-1

for x=2, y=4

table:

x   :   0     2

y   : -1       4

test point (0,0) , 0< -2

true

now we draw the graph. see the attachment for graph.

common region would be solution set.

option 2 is correct.
