Answer:
coordinates of A are (11/2, -3/2)
Step-by-step explanation:
midpoint = M(5, −4)
start point = A(6, 1)
endpoint = B(x, y)
equation :
x = m1 × x2 + m2 × x1 y = m1 × y2 + m2 × y1
_____________ _____________
m1 + m2 m1 + m2
x = (1 × 6) + (1 × 5) y= (1 × 1) + (1 × -4)
_____________ ____________
1 + 1 1 + 1
x = (6+5 )/ 2 = 11 / 2 y = (1+(-4))/2+(1-4)/2 = -3/2
∴coordinates of A are (11/2, -3/2)

Answer:
6√2
Step-by-step explanation:
Gm = √a×b
= √4×18
= √72
= √36×2
= √6²×2
= 6√2
The values of the variables are k = -6 , w = ± 9 , f = -7
Step-by-step explanation:
To solve these problems we will compare the elements inside the [ ]
[-12 , -w²] = [2k , -81]
[2f , 3] = [-14 , 3]
That mean:
1. -12 = 2k
2. -w² = -81
3. 2f = -14
∵ 2k = -12
Divide both sides by 2 to find k
∴ k = -6
∵ -w² = -81
Divide both sides by -1
∴ w² = 81
Take √ for both sides
∴ w = ± 9
∵ 2f = -14
Divide bith sides by 2
∴ f = -7
The values of the variables are k = -6 , w = ± 9 , f = -7
