Answer:
The answer to your question is: (4, -1)
Step-by-step explanation:
M = midpoint (-1, 1)
A = (-6, 3)
B = (x, y)
x = 2xm - x1
x = 2(-1) + 6
x = -2 + 6
x = 4
y = 2ym - y1
y = 2(1) - 3
y = 2 - 3
y = -1
Combine like terms: 18a - 8b -1
It is 8 because you divided it
Answer:
D.20 + 2/10 units
Step-by-step Explanation:
Perimeter is the distance all round a figure.
AB = 10. This is given in the question
AC = √((3-5)²+(4--2)²
= √(4+36)
=√40 = 6.32 units
BC = 5 - -5 = 10 units
Perimeter = AB+AC+BC
= 10+6.32+10
= 26.32 units
From the choices, we do not have an exact answer. The one that mosts suits the perimeter is 20 + units.
