What do the letters in algebra mean?
x, y, z are variablesa, b, c, etc. are constants
What dose Variables mean?
Variables mean whose values are not constant, such as x, y , z this is in algebra
What is a variable in algebra?
A variable is a symbol that represents an unknown or changeable number, typically a letter such as x, y, and z.
What do you use to represent a variable in algebra?
Any letter in the alphabet can be used to represent a variable in algebra.
How do you factorise brac x-y brac squared - z sqaured brac. stands for bracket?
(x - y)2 - z2 is a difference of two squares (DOTS), those of (x-y) and z. So the factorisation is [(x - y) + z]*[(x - y) - z] = (x - y + z)*(x - y - z)
What are the Properties of equality in algebra?
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
How do you discrbe algebra?
Algebra is a form of math in which you find the values of things using variable (eg. x,y,z).
What do the letters in algebra mean?
x, y, z are variablesa, b, c, etc. are constants
What are the properties of algebra?
There are quite a few, but here are some:The distributive x(y+z)=xy+xzThe associative x+y=y+xand many others!
What does y mean in algebra?
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.
What dose Variables mean?
Variables mean whose values are not constant, such as x, y , z this is in algebra
If x is y and y is z which statement must be be true?
If x = y and y = z then x = z
What are the boolean theorems?
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.
What is the answer for y plus z in pre algebra?
If you know the values of ' y ' and ' z ', then the answer is the same no matter where you are.
Possible subsets of x y z?
There are 8 different subsets. The null set. {x} {y} {z} {x y} {x z} {y z} {x y z}
What is a variable in algebra?
A variable is a symbol that represents an unknown or changeable number, typically a letter such as x, y, and z.
What is the algebra vocabulary for variable?
In algebra, a variable is usually symbolized by the letter x. For more complex problems, the letters y and z are often used as well.
