c) y=10x-9
d) y=14x+15
e) y=6x-8

Answer 1

Resposta:

a)y= 3x+5

3x+5=0

3x=-5

x=-5/3

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

b) y= -4x+6

-4x+6=0

-4x=-6

x= -6/-4

x= 3/2

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

c) y= 10x-9

10x-9= 0

10x= 9

x= 9/10

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

d) y=14x+15

14x+15= 0

14x= -15

x= -15/14

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

e) y= 6x-8

6x-8= 0

6x= 8

x= 8/6

x= 4/3
