Answer 2

Resposta:

ITEM (D)

Explicação passo-a-passo:

$\blue {{ _{\heartsuit} } \heartsuit_{\heartsuit} } \: \: \mathsf {OI, TUDO \: \: J\acute{O}IA \: ? \: \:\blue {{ _{\heartsuit} } \heartsuit_{\heartsuit} } }$

$\mathtt{ x_{a} = 1 } \\ \mathtt{ y_{a} = 0 } \\ \mathtt{ x_{b} = 3} \\ \mathtt{ y_{b} = 10}$

$\mathtt{ x_{m} } = \mathtt{ \dfrac{\left( x_{a} + x_{b} \right)}{2} }$

$\mathtt{ x_{m} = \frac{1 + 3}{2} } \\ \mathtt{ x_{m} = \frac{4}{2} } \\ \mathtt{ x_{m} = 2}$

$\mathtt{ y_{m} = \dfrac{ \left( y_{a} + y_{b} \right) }{2} }$

$\mathtt{ y_{m} = \frac{\left( 0 + 10\right)}{2} } \\ \mathtt{ y_{m} = \frac{10}{2} } \\ \mathtt{ y_{m} = 5 }$

$\red{\mathtt{ x_{m}(2,5) }}$
