Does this set of ordered pairs represent a function? why or why not? {(–5, –5), (–1, –2), (0, –2), (3, 7), (8, 9)} a. yes, because there are two x-values that are the same. b. no, because two of the y-values are the same. c. no, because one x-value corresponds to two different y-values. d. yes, because every x-value corresponds to exactly one y-value.

Me figure out the process to determine x you appreciate it : )

Acamper leaves camp on a kayak and travels 50 miles east on a river, then he ties his kayak to the bank and travels 20 miles north on a bicycle. this trip can be plotted on the coordinate plane, where the camp is the point (0, 0). the distant of the camper to the camp can be found using the distance formula. which other formula can he use? a) 502 - 202 b) 502 + 202 c) 502 - 202 d) 502 + 202

Which equation represents a line that is parallel to the line whose equation is 3x-2y=7( show all work)
