Sum :
Term : 1, and
Product : and
Factor : 5 and x, 3 and y, 9 and 5x+1
Quotient :
Coefficient : 5 is the coefficient of x and 3 is the coefficient of y.
Explanation:
The expression is
Sum: Sum is the result of addition of terms.
Thus, from the expression,
Sum =
Term : A term is a single number or a variable or a number multiplied with a variable.
Thus, from the expression,
Term = 1, and
Product : Product is the result of multiplication of numbers.
Thus, from the expression,
Product = and
Factor : The numbers that are multiplied is called a factor.
Thus, from the expression,
Factor = 5 and x, 3 and y, 9 and 5x+1
Quotient : Quotient is the result of dividing two numbers or variables.
Thus, the given whole expression is a quotient.
Hence, Quotient =
Coefficient : Coefficient of a variable is a number multiplied with a variable.
Thus, from the expression,
Coefficient : 5 is the coefficient of x and 3 is the coefficient of y.
Step-by-step explanation:
(a)
Using the definition given from the problem
Therefore it is true for intersection. Now for union, we have that
Therefore, for this case, it would be true that .
(b)
1 is not a set.
(c)
To begin with
Therefore
Now, given an element of it will belong to both sets, therefore it also belongs to
, and you would have that
, therefore
.
(d)
To begin with , therefore
