Can someone me on the multiple choice 1-3 ? im stuck

1. (4)x + y =50

  2x + 4y =172

2. (1)x + y =8

   150x + 50y =800

3. (1)x + y =20

   25 + 10y =290

Step-by-step explanation:

Just trust me and its too much work explaining and im lazy so just ask your teacher or a friend if you can.

answer: a and b

step-by-step explanation:

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.
