Please help me!!! The table below represents the velocity of a car as a function of time: time Velocity seconds (m/s) x f (x) 15 45 22 66 29 87 36 108 The average rate of change of the function between x = 15 to x = 29 is __________m/s2 and represents the car's acceleration

Read my question, and then look at this message for my results!
I think I understand how to do this... here's my work. 4a - 2 < a + 1 < 3a + 4 I separated them into two pieces: 4a-2 < a + 1 and a + 1 < 3a + 4 Then, I added two to each side of the first one, and took away 1 from each side of the second one. 4a < a + 3 and...

4a-2 (less than or equal to) a + 1 (less than or equal to) 3a + 4 I'm assuming I should put this on a line, like I did with some other problems on my worksheet, right? But I have no idea how I would show 4a-2 on a line! I have no idea how to do this. Thank you so much!

Solve 3x +1 < 5 or 3x +1 > 4 By saying "solve," is it asking for me to show it on a line and in interval notation? Here's another: f(x) < 3 and f(x) > 4, where f(x) = 1/2x - 7 I have no idea how to solve this! Please walk me through it! Thank you so ...
