Question

Determine o valor de x para que o ponto M(4, 6) seja o ponto médio do segmento de extremos A(x , 5) e B(3 , x).​

Answer 1

Resposta:

x = 9

Explicação passo a passo:

A(x + 5) e B(3, y)

$\frac{x_A+x_B}{2} =x_M\\\\\frac{x+3}{2}=4 \\\\x+3=12\\\\x=12-3\\\\x=9\\\\\frac{y_A+y_B}{2}=y_M\\\\\frac{5+y}{2}=6\\\\ 5+y= 12\\\\y=12-5\\\\y=7$
