Answer:

The answer to your question is:    Y = (13, -14)

Step-by-step explanation:

Data

midpoint = mp = (6, -3)

one endpoint = X = (-1, 8)

second endpoint = Y = (x, y)

Formula

Xmp = (x1 + x2) / 2

Ymp = (y1 + y2) / 2

Process

                    x2 = 2xmp - x1

                    y2 = 2ymp - y1

                   x2 = 2(6) - (-1)                     y2 = 2(-3) - 8

                   x2 = 12 + 1                          y2 = -6 - 8

                   x2 = 13                               y2 = - 14

                   Y = (13, -14)

The ratio of money in Terry's bank account to Faye's bank account was 3:7. Terry then put £220 in his account and Faye withdrew
Nesterboy [21]

Answer:

£910

Step-by-step explanation:

let 3x and 7x be the initial amounts in their accounts, then after alterations

Terry has 3x + 220

Faye has 7x - 300

After these changes the amounts are equal, hence

7x - 300 = 3x + 220 ( subtract 3x from both sides )

4x - 300 = 220 ( add 300 to both sides )

4x = 520 ( divide both sides by 4 )

x = 130

Faye initially had 7 × £130 = £910 in her account
