Question

Let x = [10/-3]and y =[-1/-5] then he distances between x and y is

Answer 1

Answer:

Correct option is

A

x = 7

B

x= -1

Distance between two points (x

1

,y

1

) and

(x

2

,y

2

) can be calculated using the

formula

(x

2

−x

1

)

2

+(y

2

−y

1

)

2

Distance between the points (x,−1) and (3,2)=5

=>

(x−3)

2

+(−1−2)

2

=5

(x−3)

2

+9

=5

(x−3)

2

+9=25

(x−3)

2

=16

x−3=+4 or −4

x=7 or x=−1
