If x represents a number, does 2/5 times x always represent 40% of that number?

Yes, it always represent 40% of that number.

Step-by-step explanation:

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.
