Lauren pays a total of $23 for 5 away flights and 4 return flights. The next year she pays $16 for 4 return flights and
2 away flights. How much does an away flight cost, and
how much does a return flight cost? Write a system of
equations to describe the situation below, solve using
elimination.

Determine the domain and range of the given function. the domain is all real numbers all real numbers greater than or equal to –2{x: x = –2, –1, 0, 1, 2}{y: y = –2, –1, 0, 1, 2}. the range is all real numbers all real numbers greater than or equal to –2{x: x = –2, –1, 0, 1, 2}{y: y = –2, –1, 0, 1, 2}.
