For which equation is s = 6 not the solution? 4 s = 24
9 - s = 4
s + 6 = 12
s - 4 = 2

9 - s = 4

3 doesn't = 4 so we know this one isn't it

9 - s = 4

Step-by-step explanation:

9 - 6 is 3, not 4, so thats the answer!

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.

step-by-step explanation:

the answer is 128
