What are vectors and what are the 2 properties of them?
Vectors are quantities that have a value as well as a direction.Vector addition is commutative: x + y = y + xThe value of the sum of two vectors is always less than or equal to the sum of their individual values.|x + y| ≤ |x| + |y|
The sum of x and y decreased by their product?
The sum of x and y decreased by their product is (x + y)- xy.
What two numbers have a sum of ten and a difference of twenty?
15 and -5 x + y =10 x - y = 20 So it is eventually discovered that x = 15 and y =-5, if you solve the equations.
The sum of x and y?
x+y
