P is an odd number. Q is an even number. Explain why P × Q + 1 is always an odd number?

An odd number times an even number is always even

e.g 2 × 3 = 6

4 × 5 = 20

adding 1 to an even number makes it odd

6 + 1 = 7

20 + 1 = 21

hope this helps...

P is an odd number

Q is an even number

Now, product of a odd number and even number is always even number.

Therefore, P×Q is a even number

Now, by adding 1 to the even number it becomes odd.

Hence, P×Q+1 is always an odd number.

answer: domain and range mean all possible values of x and y that could be substituted to the inequality. a solution means all possible values that make the inequality statement true. so while the range is still all real numbers, the solution is the shaded area, for which y will always be greater than the line of the function.
