It said y is > greater than or equal to 5x

         y is > greater than or equal to 3

         x + y is < less than or equal to 6

@ baladya examle plz!!!!
4 compond interst

[Shazizzzle]

Yeah, it say Y is greater than and equal to 5x.
Therefore, the required region is where Y values are greater. And, using the y axis, and the line y=5x, which region has the greater ones?
The one ON TOP.

Greater means greater values.
Not greater, as in, it will be AHEAD.

If so then ... im wrong.

check the attached image

ai) VW = VU + UX + XW = -a + b + 2a = a+b

aii) TU = TX + XU = a-b

aiii) TP = TW + WP = 3a+b

aiv) OP = OZ + ZP = 1.5a + 0.5b

b = a-b = TU = 4 units

cn u explain me y is adzels ans wrong..... because i gt the same

Help in  Q23 . JUne 2006 P2 >  plz
its making me lose my mind..
 
Thanks in advance

23 a) VW = a + b
simply because VW is in the same direction as a and b

ii)TU = a - b
TU in the same direction as 'a' but opp. to 'b'

iii) is attached .. its a bit complicated ..




wonder how i got UA as 'b'
VA is clearly b-a
so 'UA' + AV should be equal to "a"
so UV = UA + AV
a = UA +  a - b
so UA = b

same stuff for BP WB also which gives us a

so adding UA , AB , BP and TU u get TP
=b + (a +b) + a
= 3a +b

gosh pls. dont freal out if u dont understand .. i did my best to explain ..

iv) from origin position ov p is 1/2 TP
= 1.5a + 1/2 b
 v) is simply count no. of blocks of TU = 4
