It’s so cool seeing someone perfectly explain something like this. You helped remind me of something that I knew and just got straight to the point of the answer. Thank you so much!

[@Buckeye_2014]

Thanks you sir

[@kaushalmeda272]

at 41:56, you just use the vertex formula to get the value of m faster because the only possible way to have 1 X-intercept is at the vertex. The formula -b/2(a) = the x value of the vertex, therefore when you use that you can easily get m = -8

[@5Academy]

great approach!

[@timber5023]

Great video. Thanks for the help.

[@Littlebrownbatz]

It gives me anxiety as the battery slowly drains throughout the video.

now I can't stop looking at it😭

[@reethamgubba2048]

I'm confused.For the first question, why can't the answer be D?

[@h.op.e7209]

Since they're testing our ability to picture the lines and understanding that as long as different y-int are used (as long as z doesn't equal 1) the lines will always be parallel. D isn't a good option because it only represents *one* option for no interception, whereas A gives the "all encompassing" value; any number, as long as it's not 1 will be correct so in this case it's the best answer.

[@Noli6663]

D works since it's not a 1, but since ANY number that isn't 1 would work it isn't the most accurate choice. Many of the ACT problems have answer choices that are true but aren't the best option, so make sure you check for that when you take the test.

[@ParthivPatel-uu8xw]

@@Noli6663 I agree, I believe they are looking for the most accurate answer, and D is not the most Precise, A is .

[@monikwaa]

in 35:39 why did you multiply it by 2? im not familiar with this part yet so im confused

[@Appleee..]

Yeah, I'm still somewhat confused on why he did that; however, there's actually a few youtube videos that guided me through how to solve overflow problems using log on your calculator. Hope this helps!11

[@kovo7]

every hundred adds 2 zeros and the question is asking for number of zeros

[@ParthivPatel-uu8xw]

If you were to square it, it would be 2(2), the first represents the number of zeroes in your base, and the second is your power. the output would give you the total amoutn of zeroes. Similarly, we are are putting 100 to the power of 100, which is to the power of 100. That means that it would be 2, which is the number of zeroes in 100, times 100^100, which is the exponent. Giving the result of 2(100^100)

[@ParthivPatel-uu8xw]

hope that helped

I’m taking the paper act and I was wondering if calculators were allowed on the entire math section of the test?

[@AlabasterHawkins]

yes, they are! ive taken the paper act twice already

[@idexxyy2511]

the first question asks which answer will have no solution, so shouldn't it be B? because if it equals one then it intersects at every point

[@alenawang3129]

if z equals 1, then the system would have infinite solutions, not no solutions.

[@5Academy]

^that's correct! 👍

my problem is that I don't even know the formula by heart TT____TT
