Question

Calcule o valor numérico de $\frac{- x^{2} +xy}{y}$, para x = -0,1 e y = 0,001

Answer 1

$\frac{- x^{2} +xy}{y} \\\\Para \to x = -0,1 ; y = 0,001\\\\\\ \frac{- (-0,1)^{2} +(-0,1)*0,001}{0,001} \to\\\\ \frac{- 0,01 +(-0,0001)}{0,001} \to \\\\ \frac{- 0,01 -0,0001}{0,001} \to\\\\ \frac{- 0,0101}{0,001} \to\\\\ -10,1$
