14500(4/5)^n

Slope is 4

y=4x+b      includes point (3,1)

1 = 4(3) + b

-11 = b

y = 4x -11

Rewrite   4x+3y=3

               3y=-4x+3

                 y = -4/3x +1      where =-4/3 is the slope....parallel line will have same slope

y = -4/3 x + b    includes 2,3

3 = -4/3 (2) + b

3+8/3 = b

b = 5 2/3

so NEW line is    y = -4/3x + 5 2/3      m = -4/3   b = 5  2/3

Is the same as

9x + (-1)(6-x)

9x -6 +x

10x-6

PEDMAS    says do the mult first 

-1/4 x -8 = 2      then do the add,

-2 +2 = 0

A quick google search seems to say that Jesus was born 6-4 BC   (There are historical records which seem to document his birth and life....whether you believe he was the Son of God is another matter....but that does not change the legitimacy of the question)        Let's say 5 BC   ...if he WERE alive today he would be

5 + 2018 = 2023 years old.

Second one

Which of the combos provides for 112 desserts?

3 pies * 8 pieces/pie   +  8 batches * 12 pieces/batch  = 112?

        24 pieces   + 96 pieces = 120    does NOT equal 112        This will work with some desserts left over.........try the others to see if ONE of them equals 112 pieces......pick the one that provids at LEAST 112 pieces with the least amount left over.

T= mv^2/r      Solve for 'v'    1st : Multiply both sides of the equation by 'r'

Tr = mv^2      Then divide both sides by 'm'

Tr/m = v^2     Take the sqrt of both sides

sqrt( Tr/m) = v  

Very well. thank you.   And how do YOU simplify fractions? 

Do you have some examples with which you need some help?
