ME AJUDE PRECISO ORA AMANHÃ

Answer 1

Resposta:

a) f(x) = 4x + 32

4x = 32

x = 8

b) f(x) = -3x + 30

-3x = 30

x = 30 / 3

x = 10

c) f(x) = -2x + 16

-2x = 16

x = 16 / 2

x = 8

d) f(x) = 3x - 36

3x = -36

x = -36 / 3

x = -12

e) y = 8x - 40

0 = 8x -40

-8x = -40

x = 5

e) y = -10x - 40

0 = -10x - 40

10x = - 40

x = - 4

f) y = -7x - 40

7x = - 40

x = - 40 / 7

x = -5,7...

g) y = 4 x - 40

- 4x = -40

x = 10

h) y = 7x - 42

- 7x = -42

x = 6

i) y = 8x - 40

8x = -40

x = 5
