The answer is (7, -26) for The second endpoint.
We'll call the midpoint M. In order to find this, we must first note that to find a midpoint we need to take the average of the endpoints. To do this we add them together and then divide by 2. So, using that, we can write a formula and solve for each part of the k coordinates. We'll start with just x values.
(Ux + Vx)/2 = Mx
(Vx + 3)/2 = 5
Vx + 3 = 10
Vx = 7
And now we do the same thing for y values
(Uy + Vy)/2 = My
(Vy + 6)/2 = -10
Vy + 6 = -20
Vy = -26
This gives us the final point of (7, -26)

Answer:
Step-by-step explanation:
12P3 = 12! / (12-3)!
= 12*11*10
= 1320.
8C7 = 8!/7! *(8-7)!
= 8.
Answer:
(30) = 4
Step-by-step explanation:
g(x) = 8x -2
Let g(x) = y
y = 8x -2 (note: y is the range and x is the domain, we need to rearrange to make x the range and y the domain instead)
y + 2 = 8x
x = (1/8) (y + 2)
hence the inverse of g(x) is (y) = (1/8) (y + 2)
(30) = (1/8) (30 + 2) = 4
