Given: AC = CD and BC = EC Prove: AB
ED
8
Statements
AC = CD, BC = EC
AC + BC = CD + BC
AC + BC = CD + EC
Reasons
Given
AC + BC = AB; CD + EC = ED
AC + BC = AB; AC + BC = ED
AB = ED

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.

hi there, i would be interested to you with your test, may you add the questions and answer options.
