Question

Y=5x-10/2, 4x+5=-y (find the determinant)

Answer 1

Answer:

Friends are the jewels of life! you should ask them they will help you

Answer 2

let the y = 1y

the x = 1x

A.T.Q

1 = 5 × 1 - 10/2 , 4 × 1 + 5 = -1

1 = 6 - 10/2 , 4 + 5 = -1

1 = 12 - 10/2 , 9 = -1

1 = 1 , 9 = -1

So,. it is satisfied. , it is not satisfied.
