Question

Determine os 0 da função abaixo​

Answer 1

Explicação passo-a-passo:

a)

x+8 = 0 => x = -8

b)

5x - 15 = 0 => 5x = 15 => x = 15/5 => x = 3

c)

x/4 - 21 = 0 => x/4 = 21 => x = 4.21 => x = 84

d)

190x = 0 => x = 0/190 => x = 0

e)

-5x/2 + 9/4 = 0 => -5x/2 = -9/4 => x = (-9/4)/(-5/2) => x = -9/4.(-2/5) => x = -9/-10 => x = 9/10

f)

-x = 0 => x = 0

g)

x = 0

h)

100 - 7x/9 = 0 => -7x/9 = - 100 => x = -100/(-7/9) => x = -100.(-9/7) => x = 900/7
