Alguém ajuda ai nmrl 2) Marque a alternativa abaixo que não está correta:
a) 2,5 E Q
b) 3,2 11
c) 0,8 Q
d) 2,236817...
e) 1,732168... Q

option 1 is correct.

step-by-step explanation:

y varies inversely with x and constant of variation is 4

the equation will be:

y = k/x

where k =4 so,

y = 4/x

if we put values of x of option 1 in the above equation and find values of y

y = 4/-2 => y =-2

y = 4/-1 => y = -4

y = 4/1 => y = 4

y = 4/2 => y =2

so, all the values of x and y are correct.

if we put values of x given in other options and find value of y we cannot find whole table satisfying the equation.

hence option 1 is correct.

this is false ^.^ lol
