Find the value of d and YZ if Y is between X and Z.
XY = 11d, YZ = 9d – 2, XZ = 5d + 28

d=2 YZ=16

Step-by-step explanation:

XZ=XY+YZ

5d+28=11d+9d-2

28=11d+9d-2-5d

28+2=15d

30=15d

2=d

YZ = 9d - 2 = 9. 2 0 2 = 18 - 2 = 16

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.
