ME AJUDEM URGENTE
Encontre a raiz das seguintes funções:
a) f(x) = 2x – 10
b) f(x) = 4x + 8
c) f(x) = -50 + 5x
d) f(x) = 8 + 3x
e) f(x) = - 6x
f) f(x) = 3x - 1​

Answer 1

Explicação passo-a-passo:

a)

$\sf 2x-10=0$

$\sf 2x=10$

$\sf x=\dfrac{10}{2}$

$\sf \red{x=5}$

b)

$\sf 4x+8=0$

$\sf 4x=-8$

$\sf x=\dfrac{-8}{4}$

$\sf \red{x=-2}$

c)

$\sf -50+5x=0$

$\sf 5x=50$

$\sf x=\dfrac{50}{5}$

$\sf \red{x=10}$

d)

$\sf 8+3x=0$

$\sf 3x=-8$

$\sf \red{x=\dfrac{-8}{3}}$

e)

$\sf -6x=0$

$\sf 6x=0$

$\sf x=\dfrac{0}{6}$

$\sf \red{x=0}$

f)

$\sf 3x-1=0$

$\sf 3x=1$

$\sf \red{x=\dfrac{1}{3}}$
