Question

Determine os zeros das funções do 1 grau de y=x/3-5/2

Answer 1

Explicação passo-a-passo:

$y = \dfrac{x}{3} - \dfrac{5}{2}$

$0 = \dfrac{x}{3} - \dfrac{5}{2}$

$0 - \dfrac{x}{3} = - \dfrac{5}{2}$

$- \dfrac{x}{3} = - \dfrac{5}{2}$

$\dfrac{x}{3} = \dfrac{5}{2}$

Multiplique cruzado

$2 \times x = 3 \times 5$

$2x = 15$

$x = \dfrac{15}{2}$
