The solution set of the inequality x > is the union of two intervals. Identify those two intervals. O (-,-1) O (0, ) O (0, 1) O (-, 0) O (-1,0) O (1, )

A doctor sees between 7 and 12 patients each day. On Mondays and Tuesdays, the appointment times are 15 minutes. On Wednesdays and Thursdays, they are 30 minutes. On Fridays, they are one hour long. The doctor works for no more than 8 hours a day. Here are some inequalities that represent this situation. - .25 is less than or equal to y is less than or equal to 1 - 7 is less than or equal to x is less than or equal to 12 -  What does each variable represent? What does the expression in the last inequality mean in this situation?

Identify the values of x satisfying both |x − 7| < 6 and |x − 9| < 5. - (Give your answer as an interval in the form (*.*). Use the symbol ∞ for infinity, U for combining intervals, and an appropriate type of parenthesis "(",")", "[","]" depending on whether the interval is open or closed. Enter Ø if the interval is empty. Express numbers in exact form. Use symbolic notation and fractions where needed.) X E
