I’ve always wondered why the UK uses the letter “c” for the y-intercept? In the U.S., for some reason, we use “b.” As in, y = mx + b. I also noticed that in the UK, there are a fair number of questions about intervals and frequencies. They are similar in substance to inequality problems, but we rarely see them here. Anyway, I think this guy is one of the best math teachers on KZitem. Mr. Hagerty is also an another awesome teacher from England. And as I’m sure you know, we say “math,” not “maths.” Why are you making a singular noun plural? We don’t say “biologys” or “historys.” Frankly, I kind of enjoy the way you guys do things across the pond much better, and not only in education…in most things! I’ve started using the words “proper” and “brilliant” more in everyday conversations more, the way you often do. I hope to vacation there again soon. Thanks for your valuable videos.

Hi and thank you very much for these kind words. I actually don't know why we use c and not b (and was not aware you use b actually) so I will research this after! We use maths to be short for mathematics. Have you ever heard someone refer to statistics as "stats"? Or do you call it "stat" for short? Or perhaps you just say "statistics" in full? I have no idea :)

For Q14, I proved why 5x-20 has to = 90 as I already knew that that was the value due to the question. Therefore, I added 20 to 90 to get 110, and divided by 5 to get 22. Using x=22, I applied it to the 2 other angles and then added up all the angles (90+55+35) to get 180. As this also proves that it is a right angled triangle, but I used a different formula, would I still get the marks, or would I have to do it the way that you did?
@1stClassMaths

Quite possibly but there is no reason to suspect that this angle was the 90 degree angle. Had I not included a diagram and just gave the expressions how would you choose? The best method is the one I showed but your one will probably be awarded full marks still.

We want to show that the time is at least 15 minutes so we need to show that all of the times are above 15. For this we are interested in the lowest possible time. If you did the higher possible time and found out that it was 24.9 minutes that isn't helpful as it just tells you that all times are below this. It doesn't guarantee though that some times aren't below 15. So instead we find the lowest time at 15.4 minutes. If you prefer you want find both and show that times are all between 15.4 and 24.9 minutes, and so they are all greater than 15 but hopefully you can now see that the only one that matters it the lowest one.

You can draw a line down but you shouldn't be using 1cm anywhere in your calculations. I don't understand what you mean by horiztonal distance but I expect your error is with the 1. The problem is if you draw the line down and call his new point say D, you won't know the length of AD or DB. (I think that you think AD = 12 but it is not).
