@heady cipher

#

what part

heady cipher Mar 17, 2025, 2:25 PM

#

both b's

junior zenith Mar 17, 2025, 2:25 PM

#

what did you get for a

heady cipher Mar 17, 2025, 2:26 PM

#

(5,1,-2) + d(-1,-2,5)

#

=r

junior zenith Mar 17, 2025, 2:27 PM

#

alr

#

so you've got two lines

#

how would you find the point of intersection

heady cipher Mar 17, 2025, 2:28 PM

#

equate them

#

find d and muo

junior zenith Mar 17, 2025, 2:29 PM

#

yh

#

if they intersect, then you'll have a value for d and mu

#

make sure to check the values are consistent with each equation

#

my final answer for P was (0,5,-12) but it says it's wrong

#

and when i used that value of P in bii i got the most foul numbers

#

heady cipher my final answer for P was (0,5,-12) but it says it's wrong

should be (7,5,-12)

#

i redid bi so 3 times and got 0 instead of 5 in the x term

#

could you send me your working please

#

i got d=2 and mou=3

junior zenith Mar 17, 2025, 2:38 PM

#

when equating you should get these three equations

-8 + 5u = 5 - l
5 = 1 - 2l
-6 - 2u = -2 + 5l

heady cipher ---

dont suppose if you recall either

the final answer to b ii is a messy fraction
a nice integer

I got the former
