a) F(x) = 6x + 12
b) F (x) = 3x + 17
C) F (x) = 5x – 65
d) F (x) = 2x - 90
e) F (x) = 5x – 4865

Answer 1

Resposta:

Explicação passo-a-passo:

a) F(x) = 6x + 12

0 = 6x+12

-12 = 6x

6x = - 12

x = -12/6

x = - 2

b) F (x) = 3x + 17

0 = 3x+17

- 17= 3x

3x = - 17

x = - 17/3

C) F (x) = 5x – 65

0 = 5x - 65

65= 5x

5x = 65

x = 65/5

x = 13

d) F (x) = 2x - 90

90 = 2x

2x = 90

x = 90/2

x = 45

e) F (x) = 5x – 4865

0 = 5x - 4865

4865 = 5x

5x = 4865

x = 4865/5

x = 4800/5 + 65/5

= = 960+13

x = 973
