Which inequality is true when x= 4 -25x > 100 -25x _> 100 25x < 100 25< _100

Step-by-step explanation:

Put the value of x = 4 to each inequality:

-25x > 100 → -25(4) > 100 → -100 > 100 FALSE

-25x ≥ 100 → -25(4) ≥ 100 → -100  ≥ 100 FALSE

25x < 100 → 25(4) < 100 → 100 < 100 FALSE

25x ≤ 100 → 25(4) ≤ 100 → 100 ≤ 100 TRUE

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.
