    Why did my instructor become angry when I asked to repeat some of the steps?

    • @moominageanga7005
      @moominageanga7005 4 года назад +28

      Mali Rabbit that’s because your instructor is somewhat rude. Teachers are supposed to answer school relevant questions without judging or becoming angry at the student. I hate it when my teachers do that.

    • @angrydlc
      @angrydlc 3 года назад +35

      thats because the instructor doesnt know it himself without a script

    Hi tech math, last time I commented was you showing how exponential growth related to cov19 about 3 months ago. I think you're an aussie or kiwi. You showed up this morning on my noti. How are things? Well we're kinda in limbo here in the US. I think it's all about the elections and a vaccine at this point. Your country did a great job, ours...🤔. I resubd just to get a noti again. Wishing you well and glad to see you on my list again. Be safe.

    • @doctorwave
      @doctorwave 2 года назад

      Linear equations will have no powers. They will also match the amount of lines with number of variables.

    your Z is actually -5 since you will move it to the right side it will be negative so 11 - 16 not 16 - 11 :)

    • @FiveTwo_Nick
      @FiveTwo_Nick 10 месяцев назад

      You will be left with -z =-5, so z =5 is correct

  • @lynskyrd
    @lynskyrd 3 года назад +1

    WHY - WHY do people put up examples using z instead of another letter that doesn't require them to put an extra line through it to distinguish it from the number 2 ? And yet- they put a line through the seven that doesn't even need it? It's too easy to forget the line through the z which could be confused with a two. Or, the horizontal line could turn into a negative if it's written carelessly. Eliminate it all together- don't use the letter z. Less is more.
    3x + 2y - c = 11
    2x -3y + c = 7
    5x + y - 2c = 12
