Which graph represents the solution set for the system x + 2y 3, x + y 4, and 3x − 2y 4?

1 answer:

4 0

x + 2y + 3 = 0
Subtract x from both sides.
2y + 3 = -x
Subtract 3 from both sides.
2y = -x - 3
Divide by 2 on both sides
y = -(x+3)/2

x + y + 4 = 0
Subtract x and 4 from both sides
y = -x - 4

3x - 2y + 4 = 0
Subtract 3x and 4 from both sides.
-2y = -3x -4
Divide by -2 from both sides.
y = -(3x + 4) / 2

The answer is the graph that contains these slopes and lines on the graph, which was not provided.

Answer:

Yes they are congruent

they are congruent by SSS rule that is Side Side Side rule

AB = CB (given side) in the question itself

Db = BD (common side)

thats why by SSS rule they are congruent

Might be 134 because since angle 2 and 8 are lined up like that it is same side exterior angles which means they are supplementary from each other so they will equal 180. So I did 180-46 to get 134, I’m not sure if I’m correct
