Question

seja m 3,3 o ponto médio do segmento AB ache as coordenadas do ponto a sendo B 0,6​

Answer 1

$\mathtt{A(x_{A}, y_{A})=? }$

$\mathtt{M(3,3)}$

$\mathtt{B(0,6)}$

Solução:

$\mathtt{x_{M}=\dfrac{x_{A}+x_{B}}{2}}\\\mathtt{3=\dfrac{x_{A}+0}{2}\to~x_{A}=2.3=6}$

$\mathtt{y_{M}=\dfrac{y_{A}+y_{B}}{2}}\\\mathtt{3=\dfrac{y_{A}+6}{2}}\\\mathtt{y_{A}+6=2.3}\\\mathtt{y_{A}+6=6\to~y {A}=6-6=0}$

$\huge\boxed{\boxed{\mathtt{A(6,0)}}}$
