adding functions
yhree polynomial functions are given.
f(x) = 3x² + 5x - z
g(x) = 5x^2 – 3x + 2
m(x) = 2x^2 - 2x

part a: write an expression to represent f(x) + (g(x) - m(x).

part b: let p(x) be equivalent to g(x)-f(x). find p(x) -m(x).

part c: write an expression to represent 2[f(x) - g(x)] +3[m(x)].

-8/2y-8=5/y+4-7y+8/y^2-16

we move all terms to the left:

-8/2y-8-(5/y+4-7y+8/y^2-16)=0

we can not solve this equation

a. (14,375+570)(5.3) b. 158,417$

step-by-step explanation:

a. you are basically just setting up the equation. f= amount of debt hence 14,375. g= how much she is borrowing from her parents weekly hence 570 and t= the interest on her debt. creating the equation.

b.   14,375+570= 14,945

      14,945 x 5.3 = 79,208.5

      79,208.5 x 2(years) = 158,417(answer)
