Well it depends on what your teacher or your book says it is. You see yx and z are all letters called variables. Any letter can be a variable. The letter can equal any amount. It'll will be of course what your book or teacher says it'll be. Example: if y=3 then 7+y=3 y does not always have to be 3. it can be any number in the world. There is no permanent number for a variable. Example: if y=18 then y+2=20 You see a variable (which is any letter in the alphabet) can be equal to any number in the world.
In algebra we consider x,y and z are variables.
x, y, z are variablesa, b, c, etc. are constants
Variables mean whose values are not constant, such as x, y , z this is in algebra
A variable is a symbol that represents an unknown or changeable number, typically a letter such as x, y, and z.
Any letter in the alphabet can be used to represent a variable in algebra.
In algebra we consider x,y and z are variables.
for any real numbers x, y and z: REFLEXIVE PROPERTY; x=x SYMMETRIC PROPERTY; if x=y, then y=x TRANSITIVE PROPERTY; if x=y and y=z then x=z
Algebra is a form of math in which you find the values of things using variable (eg. x,y,z).
x, y, z are variablesa, b, c, etc. are constants
There are quite a few, but here are some:The distributive x(y+z)=xy+xzThe associative x+y=y+xand many others!
y axis ___________________________________ The letters X, Y and Z often refer to unknown or "variable" quantities, and the purpose of solving the algebra problem is to determine the precise value of these variables.
Variables mean whose values are not constant, such as x, y , z this is in algebra
If x = y and y = z then x = z
Commutative x + y = y + x x . y = y . x Associative x+(y+z) = (x+y)+z = x+y+z x.(y.z) = (x.y).z = x.y.z Distributive x.(y+z) = x.y + x.z (w+x)(y+z) = wy + xy + wz + xz x + xy = x x + x'y = x + y where, x & y & z are inputs.
If you know the values of ' y ' and ' z ', then the answer is the same no matter where you are.
There are 8 different subsets. The null set. {x} {y} {z} {x y} {x z} {y z} {x y z}
