Question

Which values for x and y make the statement (x + 3)(y – 2) = 0 true?

x = -3; y = 2

x = -3; y = -2

x = 3; y = 2

x = 3; y = -2
Which of the following gives an example of a set that is closed under multiplication?

The product of an even number and an even number

The product of a prime number and a prime number.

The product of a negative number and a negative number

The product of a perfect cube and a perfect cube

Answer 1

B

Answer 2

A

Answer 3

are you sure

Answer 4

Answer 5

if either x = -3 OR y = 2 is there the statement is true

Answer 6

product of two even numbers will give an even number so its closed under multiplication

product of two prime numbers will not give a prime number (since the resultant number can be divided from one of the prime numbers that you began with)

product of two negetive numbers will not give a negetive number (two negative numbers multiplied will result in a positive number)

\(x^3 \times y^3 = (xy)^3\) xy is a perfect cube
