Question

if (2, -2) is a root of 5-2y = k then k =
option : a) -40 b) 6 c) 14 d) 10​

Answer 1

Answer:

I think you missed the x after 5 so the question should be if (2, -2) is a root of 5x-2y = k then k =

option : a) -40 b) 6 c) 14 d) 10​

The answer to that is c)14

Because we have the root or (solution )as (2,-2) to the function 5x-2y=k

Putting the values of x and y respectively we get 5x-2y=k

or,5*2-2*(-2)=k

or,10+4=k

:.k=14
