Question

Alguém pode me ajudar?


X²+Y²=25
2X+Y=10

Answer 1

Resposta:

$(x_{1},y_{1})=(3,4)\\(x_{2},y_{2}=(5,0)$

Explicação passo-a-passo:

$\left \{ {{x^2+y^2=25} \atop {y=10-2x}} \right. \\\\x^2+(10-2x)^2=25\\\\x=3\\x=5\\\\y=10-2.3\\y=10-2.5\\y=4\\y=0\\\\(x_{1},x_{1)}=(3,4)\\ (x_{2}, x_{2})=(5,0)\\  \\\left \{ {{3^2+4^2=25} \atop {2.3+4=10}} \right.\\ \\\left \{ {{5^2+0^2=25} \atop {2.5+0=10}} \right.\\ \\\left \{ {{25=25} \atop {10=10}} \right.\\ \\\left \{ {{25=25} \atop {10=10}} \right.\\ \\(x_{1},y_{1})=(3,4)\\  (x_{2},y_{2})=(5,0)$
