Question

Encontre o zero das seguintes fumcao do primeiro grau. F(x)=5×+50
F(x)=7×77
F(x)=10×-780
F(x)=0,5×

Answer 1

Resposta:

y=x+7 0 =x+7 x=-7

f(x) = 5x + 5 5x +5 = 0 5x = -5 x=-1

f(x) = -x/2 +3 -x/2 +3 =0 -x +6 =0 -x = -6 x = 6

y=-3x+ 6 -3x + 6 =0

3x = -6 x = 2

y=-3x + 2

-3x +2 = 0 -3x =-2 x = 2/3

1) y= 2- x/2 x/2+2 = 0 -x +4 = 0 -x=.4

x=4
