Answer:
y- axis
Step-by-step explanation:
under a reflectioin in the y- axis
a point (x, y ) → (- x, y )
(5, 3 ) → (- 5, 3 ) thus the y- axis is between the 2 points
Answer:
-1/125 is a terminating decimal. -7/60 is a repeating decimal.
Step-by-step explanation:
When you convert -1/125 into a decimal, you get −
0.008.
_
When you convert -7/60 into a decimal, you get −
0.11 6.
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 = ![\sqrt{(x_{2}-x_{1})^{2}+(y_{2}-y_{1})^{2}}](https://tex.z-dn.net/?f=%5Csqrt%7B%28x_%7B2%7D-x_%7B1%7D%29%5E%7B2%7D%2B%28y_%7B2%7D-y_%7B1%7D%29%5E%7B2%7D%7D)
AB = ![\sqrt{(-1-4)^{2}+(4+1)^{2}} =\sqrt{50}](https://tex.z-dn.net/?f=%5Csqrt%7B%28-1-4%29%5E%7B2%7D%2B%284%2B1%29%5E%7B2%7D%7D%20%3D%5Csqrt%7B50%7D)
AB = 7.07 units = 7.1 units ( rounded to the nearest 10th)
Length of the side BC = ![\sqrt{(x_{2}-x_{1})^{2}+(y_{2}-y_{1})^{2}}](https://tex.z-dn.net/?f=%5Csqrt%7B%28x_%7B2%7D-x_%7B1%7D%29%5E%7B2%7D%2B%28y_%7B2%7D-y_%7B1%7D%29%5E%7B2%7D%7D)
BC = ![\sqrt{(0+1)^{2}+(-3-4)^{2}}](https://tex.z-dn.net/?f=%5Csqrt%7B%280%2B1%29%5E%7B2%7D%2B%28-3-4%29%5E%7B2%7D%7D)
BC = ![\sqrt{50}](https://tex.z-dn.net/?f=%5Csqrt%7B50%7D)
BC = 7.07 units = 7.1 units ( rounded to the nearest 10th)
Length of the side CA =![\sqrt{(x_{2}-x_{1})^{2}+(y_{2}-y_{1})^{2}}](https://tex.z-dn.net/?f=%5Csqrt%7B%28x_%7B2%7D-x_%7B1%7D%29%5E%7B2%7D%2B%28y_%7B2%7D-y_%7B1%7D%29%5E%7B2%7D%7D)
CA = ![\sqrt{(4-0)^{2}+(-1+3)^{2}}](https://tex.z-dn.net/?f=%5Csqrt%7B%284-0%29%5E%7B2%7D%2B%28-1%2B3%29%5E%7B2%7D%7D)
CA = ![\sqrt{20}](https://tex.z-dn.net/?f=%5Csqrt%7B20%7D)
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
