A point `(x,y,z)` moves parallel to xy-plane. Which of the three variables `x,y,z` remains fixed? (A) x and y (B) y and z (C) z and x (D) none of these
A point (x,y,z) moves parallel to x axis. Which of the three variables x,y,z remains fixed? (A) x and y (B) y and z (C) z and x (D) none of these
A point (x,y,z) moves parallel to xy-plane. Which of the three variables x,y,z remains fixed? (A) x (B) y (C) z (D) xand y
The distance of the point (x,y,z) from xy-plne is (A) x (B) |y| (C) z (D) |z|
The average of six numbers is x and the average of three of these is y. If the average of the remaining three is z, then x=y+z (b) 2x=y+z( c) x=2y+2z(d) None of these
If x % of a is the same as y % of b , then z % of b is a.(x y)/z % of a b. (y z)/x % of a c. (x z)/y % of a d. none of these
If the points A(x,y+z),B(y,z+x) and "C(z,x+y)" are such that AB=BC ,then x,y,z are in A .P
The image of plane 2x-y+z=2 in the plane mirror x+2y-z=3 is (a) x+7y-4x+5=0 (b) 3x+4y-5z+9=0( c) 7x-y+2z-9=0 (d) None of these
For every point P(x ,\ y ,\ z) on the xy-plane, a. x=0 b. y=0 c. z=0 d. x=y=z=0
Statement -1 If x,y,z be real variables satisfying x+y+z=6 and xy+yz+z=8 , the range of variables x,y and z are identical. Statement -2 x+y+z=6 and xy+yz+zx=8 remains same if x,y,z interchange their positions.
If x , y , and z are variables , then x + y + z is a "________" .
