Because the object is placed on the positive x-axis and y-axis but the image is formed on the negative x-axis
Your question was wrong we take concave mirror value positive and convex mirror negative

Yes in concave mirror u,v(if formed in front of mirror),f,h'(if real and inverted) are negative
Also,h,v and h'(sometimes for v and h') are positive.
