Question

4- Considerando a função y = (3x – 1) / 5 calcule o valor de y quando:



a) x = 1

b) x = 2

c) x = 3

d) x = -2

e) x = -3

​

Answer 1

Oie, td bom?

$a) y = \frac{(3.1 -1)}{5} = \frac{2}{5} = 0,4\\ \\b) y = \frac{3.2 - 1)}{5} = \frac{6 - 1}{5} = \frac{5}{5} = 1\\ \\c) y= \frac{(3.3 - 1)}{5} = \frac{8}{5} = 1,6\\\\d) y = \frac{3.(-2) - 1)}{5} = \frac{- 6-1}{5} = \frac{-7}{5} = -1,4\\\\e) y = \frac{(3.(-3) - 1)}{5} = \frac{- 9 -1}{5} = \frac{-10}{5} = -2$

Espero ter ajudado...tchau e bons estudos!!
