Question

Encontre o zero das funções: (A)Y=3×-6
(B)Y=2×-12
(C) (X)=6×-3
(D)(X)=6×-3​

Answer 1

A) y= 6x+2

0= 6x+2

-6x= 2

x=-2/6

x= 1/3

------------------

b) y= -4x +12

0= -4x +12

4x= 12

x= 12/4

x=3

----------------

c) y= x/3+6

0= x/3+6

-x/3=6

x/3= -6

x= 3*(-6)= -18

--------------------

d) y= 12x+4

0= 12x+4

-12x= 4

12x= -4

x= -4/12

x= -1/3

--------------------------

e) y= 5x+25

0= 5x+25

-5x= 25

x= -25/5

x= -5
