The midpoint of AB is M(4, -2). One endpoint is A(-2, 6). What is the other endpoint for B?
1 answer:
Answer:
endpoint for B is (10,-2)
Step-by-step explanation:
M={(x1+x2)/2,(y1+y2)/2}
(4,2)={-2+x2/2,6+y2/2)
By equating the x coordinates
4=-2+x2/2
8=-2+x2
8+2=x2
x2=10
By equating the y coordinates
2=6+y2/2
4=6+y2
4-6=y2
y2=-2
Therefore the endpoint for B is (10,-2)

Its A. x=4
procedure: 3*equation1 - 2*equation2 ⇒ x=4
Triangle D
Because the Pythagorean Theorem is only used with a RIGHT triangle
Moooooooosssssssssseeeeeeeeseseses

so the missing term in the denominator is 7^(-22)
ok done. Thank to me :>
Hi there
The formula is
I=prt
I interest earned?
P principle 7000
R interest rate 0.085
T time 120/360
I=7,000×0.085×(120÷360)
I=198.33
Hope it helps
