Two different linear functions are shown below with two points given from each function. use slope-intercept form or point-slope form to find the equation of each. linear function a points: (–5, –2), (–5, 7) linear function b points: (7, –5), (–2, –5) function a has: the equation of line a is: function b has: the equation of line b is:

Sound travels about 750 miles per hour. a) suppose it takes about 1.5 seconds to hear the echo. how far away is the canyon wall, in feet? for this i got 825 ft b) suppose you stand 1,925 feet from the canyon wall and sound the horn. how long will it take to hear the echo? (i'm stuck on this)

How are the solutions for |x +4|< -2 and |x +4| < 2 different? a they are not different, because the inequality is an absolute valueb the first inequality has no solution because absolute value cannot be negativec for one the solution is benveen two numbers. for the other, the solution is outside of the twonumbersd. for one the solution is a range of positive numbers, for the other, the solution is a range of negativenumbers
