Question in math adv test that cost me my grade since idk how to do it (1 Viewer)

soooo 4/3 is the only solution? the teacher is wrong? omg

Technically yeah but seeing as the papers already been released it’s probably too late to change. In the hsc they would probably require you to sub k back in and test if the simultaneous has a solution or not but that’s such a sac

jane pls dont hate on me for saying this again but like

am i doing a different course to the rest of you
this is insane u r definitely not at fault here there was NOTHING like that in our adv test
is there some way u can upload the full test or something because WOW im interested now

???? like theres no chance im attemping that in an exam atp

i reckon it could be 4 marks if so instead of 3

i got 1/3 for it and it was a mark for attempting the question
apparently only one kid got the full thing right from my class and my teachers explanation is too complicated surely theres an easier way

also i don't know why the fuck the teachers would even ask you this question for math advanced, this is by no means suppose to be a hard question as evident by the fact 55% of students scored 2 or 3 out of 3, this is suitable for the VCE math method since they do matricies, making this question much much easier. (this is basically a textbook question for the VCE)

my teacher wants ppl to drop from advanced to standard n the only way she can do that is by making very hard exams that no one can pass

this question can't be asked in math advanced cause its way too difficult without knowing matricies (in reality its one of the easiest questions in the vce exam since 55% scored atleast 2 out of 3 marks), its like asking someone to sketch a cubic graph with exact turning points without them knowing calculus in a year 10 exam

I totally agree. There is a separate section for this topic and many similar questions in VCE textbook. So it is an easy question for VCE students.
Although it is solvable by general quadratic knowledge, I think it is unfair to ask such a question in an exam without showing similar questions in class.
Btw, determinants are not in Math Methods syllabus in VCE either. So such solutions should not be accepted even if they are neater solutions.

@jane1820 hey idk if you already figured this out (I didn't read some of the pages), but wouldn't you just expand both equations and make them equal each other and move everything to 1 side so it is a quadratic. and then find the value of k for when the discriminant is less that 0?

ehhh not sure what you mean but yes you should get a quadratic and you should use the discriminant
but yh everyone on bos ended up helping lmao thx tho!
