Answer: i think its a im not sure sorry
Step-by-step explanation:
Perimeter of the triangle ABC is 18.7 units.
Coordinate of the point A is (4, -1), B is (-1, 4) and C is (0, -3).
Length of the side AB = 
AB = 
AB = 7.07 units = 7.1 units ( rounded to the nearest 10th)
Length of the side BC = 
BC = 
BC = 
BC = 7.07 units = 7.1 units ( rounded to the nearest 10th)
Length of the side CA =
CA = 
CA = 
CA = 4.47 units = 4.5 ( rounded to the nearest 10th)
Perimeter of the triangle ABC = sum of all three sides = (7.1 + 7.1 + 4.5) units = 18.7 units

Answer:
x=-5/11, y=-9/11. (-5/11, -9/11).
Step-by-step explanation:
3x+2y=-3
y=4x+1
---------------
3x+2(4x+1)=-3
3x+8x+2=-3
11x=-3-2
11x=-5
x=-5/11
y=4(-5/11)+1
y=-20/11+11/11
y=-9/11
