  • This algebra 2 video tutorial focuses on solving compound inequalities with fractions. It shows you how to graph the solution on a number line and how to .resent the answer using interval notation. You should use brackets for closed circles and parentheses for open circles and infinity. This video contains plenty of examples and practice problems. Compound Inequalities contain and or expressions.

    How do you produce so many videos in such a short amount of time? Every video is very detailed and shows a very strong understanding of the concept. I noticed that your oldest video is about 2 years old and since then you have produced over 1500 videos. this averages about 2 videos per day. Do you do this for fun? It seems to me that producing this many videos at such a rapid pace is financially unsustainable and you'll eventually tire yourself out.
    I am intrigued by the quantities of videos produced and would like to know your reason behind it and how you are able to support this "hobby'.

    There is a small mistake at 4:25 when he draws the number line. He accidentally puts the 1 in front of the 0 as if it is -1. He should have put it to the right of the zero, where +1 lies.

    @lindamaynard9107 2 หลายเดือนก่อน

    First, let me say that you are absolutely one of the best when it comes to explaining math. However, in this video, the second problem you demonstrated the graph is incorrect. You placed (1) to the left of zero, without a negative sign. But when you provided interval notation, the result was listed correctly; [1,5). There aren't any negative values or anything to the left of zero. Everything else is correct.

    Hello, at minute 1:35 on the video, you say to change the direction of the inequality when multiplying or dividing by a negative. Does the same rule apply if the numerator is -4 and the denominator is 2?

    • @ambulantgaming8483
      @ambulantgaming8483 3 ปีที่แล้ว +1

      Pretty sure its because when you flip the sign of something, its properties(and its relationships with the other side) flip. So here are some examples.
      5 > 2
      However, flipping 5 gives us this
      -5 < 2
