1.   Cannot see the graph

2 For every value of  'x' ,  transformed  f(x) will be shifted DOWN two units....so the entire graph will be shifted down two units from the parent graph.

P ( i) t        

  P = principal (or amount of deposit)    i = annual  interest in decimal (ex: 2%  would be i = .02)   t = time in years

1 .    y is much larger than x in the diagram.....how can x-y be positive 40?

b^3 - 4b^2 - 21b = 0       Factor out 'b'

b (b^2-4b-21) = 0          factor

b (b-7)(b+3)   = 0   

         for this to = 0     either ( b = 0)      or b-7 = 0    (b=7)     or b+3 = 0   (b=-3)

Pool area is  30 x 12 = 360 ft^2

will be bounded by walkway which is    ( 30 +2w) feet long x two   and  12 feet long x two

The width will be  'w'

(30+2w)(2) + 12(2) ) (w)  =( 1288-360)

(60 + 4w +24)w  = 928 ft^2

60w + 4w^2 + 24w

4w^2 + 84w -928 = 0      Divide by 4

w^2 + 21w - 232 = 0

 Use quadratic formula to find   w = -52/8 (extraneous)   or   8 ft wide

2 (x-3)^2 + 1 = 9    Subtract 1 from both sides of the equation

2(x-3)^2 = 8          Divide both sides by 2

(x-3)^2 = 4             SQRT both sides

x-3 = +-2           Add 3 to both sides

x = 5 or 1

Sorry....that should have been 210 gm....I have corrected it......THANX !

X = price the STORE pays for instr.

130% X   = $ 104

X = 104/(130%) = 104/1.3 = $ 80

1 x 6 = 6

3 x 2 = 6       You have to paint one number from EACH pair

So you have to paint     1  3       1   2       6  3        6 2
