What is the value of the expression when a = 5, b = 4 , and c = 6? ⁢ 4a2b/c a. 2 b.5 c.9 d. 10

A.2

Step-by-step explanation:

I took the test today XD

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.

idk this answer sorry cant on this one.
