At the start of a hike, a hiker was at a elevation of -50 feet (where 0 represents sea level). The hiker climbs at a rate of 15 per minute. Write an inequality that represents t, the number of minutes after the start of the hike, when the hiker's elevation was higher than 5 feet above sea level.

Which rule describes the composition of transformations that maps △abc to △a”b”c

Look at this system of equations. -3x + 3y = 12 y = x + 4 the solution set of this system is best explained by which of these statements? a) the graphs of the equations are the same line because the equations have the same slope and the same y-intercept. the system has infinitely many solutions. b) the graphs of the equations are parallel lines because they have the same slope but different y-intercepts. the system has no solution. c) the graphs of the equations are lines that intersect at one point because the equations have the same slope but different y-intercepts. the system has exactly one solution. d) the graphs of the equations are lines that intersect at one point because the equations have the same slope and the same y-intercept. the system has exactly one solution.
