Question

sendo F = 2(3x-1)+ 5(x-3): a) simplifique F ;  b) qual o valor de F,para X=-1

Answer 1

a)

F = 2(3x-1)+ 5(x-3)
F = 6x - 2 + 5x - 15
F = 11x - 17


b)

x = -1

F = 11.(-1) - 17
F = -11 - 17 
F = -28

Answer 2

A) F = 2(3x-1)+ 5(x-3)

F = 6x - 2 + 5x - 15

F= 11x - 17

b) f(-1) =  11(-1) - 17 ==> - 11 - 17 ==> - 28
