Given the four vectors in component form: a = 4i – 4j

b = –5i + 8j

c = –i – 3j

d = 6i + 2j

Choose the expression that produces the following resultant vectors.

6i + 9j =

2j =

–8i + 13j =

A C D B

Step-by-step explanation:

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.
