$7 / 3hr =   7/3   dollars per hour

c = 7/3 p        or  2 1/3 p       or  2.3333 p

Smallest value of the function will occur at t = -b/2a    where a = 1   b = -9        9/2 = t

    put this value of t into the equation to calculate the minimum value of the funtion which occurs at this time......

y = 3/5 b                perhaps?  

-x^2 + 2x+4     use quadratic formula to find    x = 1+- sqrt5   

                                   Use these values of 'x' in the second equation to find the corresponding 'y' points

Find the terms that result in an x^2

x^2 *7      +      2x^2 *4     + (-3x)(ax)   =   + 30 x^2

15  x^2   - 3ax^2   = 30 x^2

15 -3a = 30

a = -5

Second one   Just divide   (x-1)   into   3x^4 x^3 -25x^2 + 38x -17    via synthetic or longhand division to find (f(x)

4/25     16%   is incorrect?

Subtact 8x^4 -7x^2 + 8x -7     from both sides of the given expression     

then you will have  g(x) = ............

Triangle Inequality Theorem : This theorem states that the sum of the lengths of any 2 sides of a triangle must be greater than the third side. )

18+25=43     so 42   is a  possible

     How small can it go?  

18+7 = 25     needs to be GREATER than 25     so 8 is as small as it can go      any length from 8 to 42
