Two trucks started toward each other at the same time from towns 500 km apart. one truck traveled at a rate of 65 km per hour while the other traveled at 60 km per hour. after how many hours did they meet? if x represents the number of hours, which of the following equations could be used to solve the problem?

Ascatter plot with a trend line is shown below. which equation best represents the given data? y = x + 2 y = x + 5 y = 2x + 5

Luke started a weight-loss program. the first week, he lost x pounds. the second week, he lost pounds less than times the pounds he lost the first week. the third week, he lost 1 pound more than of the pounds he lost the first week. liam started a weight-loss program when luke did. the first week, he lost 1 pound less than times the pounds luke lost the first week. the second week, he lost 4 pounds less than times the pounds luke lost the first week. the third week, he lost pound more than times the pounds luke lost the first week.

Varies inversely with x. if y=8.5 when x=-1 find x when y=-1
