Question

Gente me ajudem urgente preciso entregar Hj!!

Answer 1

Resposta:

a) (x, y) = (8, -5)

x = 8

y = -5

b) (5, -1) = (x, -1)

x = 5

c) (x, -4) = (-3, y)

x = -3

y = -4

d) (2x, -5) = (8, y)

2x = 8

x = 8/2

x = 4

y = -5

e) (x, y + 2) = (5, 9)

x = 5

y + 2 = 9

y = 9 - 2

y = 7

f) (x + 3, 8) = (4, y)

x + 3 = 4

x = 4 - 3

x = 1

y = 8

g) (x +1, y -1) = (3, 7)

x + 1 = 3

x = 3 - 1

x = 2

y - 1 = 7

y = 7 + 1

y = 8
