Question

Dada a função do y=5x+4, calcule:​

Answer 1

y = 5x + 4

(x = -1)

y = 5.(-1) + 4

y = -5 + 4

y = -1

(x = 3)

y = 5.(3) + 4

y = 15 + 4

y = 19

(x = -2)

y = 5.(-2) + 4

y = -10 + 4

y = -6

(y = -1)

-1 = 5x + 4

-1 - 4 = 5x

-5 = 5x

x = $\frac{-5}{5}$

x = -1

(y = 14)

14 = 5x + 4

14 - 4 = 5x

10 = 5x

x =$\frac{10}{5}$

x = 2

(f(x) = 6)

(y = 6)

6 = 5x + 4

6 - 4 = 5x

2 = 5x

x = $\frac{2}{5}$
