Answer:
True
Step-by-step explanation:
Every orthogonal matrix is invertible. This is a true statement.
Orthogonal matrices are square matrix whose rows and columns are orthogonal unit vectors.
In an orthogonal matrix columns are linearly independent and since the columns are linearly independent the matrix will be matrix will be invertible. This is according to invertible matrix theorem.
The answer is: -5
Equation forms
Y=8-5x
Y-4/13=-5(x-20/13)
5x +Y-8=0
The answer is 99
-67-32=-99
distance can't be negative so its 99
