Find the smallest integer

n such that 3n > –17 .

-5 comman sense.

-6 = -18
-5 = -15

Can u help me in a question !

Can u help me in a question !

Sorry I am really weak in transformation ..

As its Shear .. the distance travelled by B in right direction = Distance travelled by C in left direction and since A is on invariant line it won't travel at all and remain the same.

Shear Factor = Distance travelled by B/(Perpendicular distance from invariant line)
Shear Factor = 8/2 = 4

Thanks
But is it always tht except the point tht lies on invariant line....other points move in opposite dirction !

 

[MustafaMotani]

u can calculate shear factor by looking at image of B
s.F = distance travelled by B/ distance from invariant line
S.F = 8/2 = 4
now calculate other cordinates with same formula
e.g. for A
4 = distane travelled / distanc from invariant line
distance travelled = 0
so A' (4,0)

for C
4 = distance travelled / -2
distance travelled = -8 so
x-1 = -8
x=-7
C' ( -7,-2)

In shear with x axis as invaariant line , y cordinates dont change..

YES ALWAYS.. IN SHEAR!

Transformation Master I am hoping P1 doesn't have a Transformation Question!

Umeed par hi duniya qayam hai ..

NO!
here they move in opposite directions because they lie on opposite side of invariant lines :|

 

[syed1995]

Well in shear technically they always do .. because they are on opposite sides on the invariant line.

Thanku so much...

Yea P2 mein aajaye utna masla nai hota...

(7*10 ^-3 ) (3*10^9)

ye to nhe pata bus ye pata hai k agar points opposite side of invariat line ho to opposite side move kartay hai

 

[convent2012]

(7*10 ^-3 ) (3*10^9)

???

 

[syed1995]

(7*10 ^-3 ) (3*10^9)

21 x 10^6
2.1 x 10^7

 

[MustafaMotani]

Thanku so much...

no prob

 

[Mayedah]

no prob

Ur good at maths

 

[Ikram Khaliq]

4/3 is ryt ms have their mistakes

10 – 3(2x – 1) = 3x + 1 .
10 - 6x + 3 = 3x +1
13 - 6x = 3x +1
12 = 9x
x = 4/3

so please don't laugh or mock someone if you don't even have an idea of the situation.
