Cecilia owns 2 cars. The cost of maintenance and fuel for each car is a function of the distance the car covers (d). Cecilia’s total monthly expenses for the first car are given by the function f(d)=d2-2d+3, and her total monthly expenses for the second car are given by the function g(d)=d2 +5.The function that gives Cecilia’s total monthly expenses for both cars is h(d).

d

step-by-step explanation:

the solution is in the picture

8(-10x+3.5y-7)

8×-10x + 8×3.5y + 8×-7

-80x + 28y - 56

therefore

-80x+28y-56 is the correct answer

since your problem is x^4 = 81, what you have to undeo is the "to the fourth power" part.

the inverse (opposite operation) of "to the fourth power" is "to the fourth root".

  (x^4) ^ ¼   = 81 ^ ¼  

  81 = 3^4     so (3 ^ 4) ^ ¼   =   3 ^ 1   = 3

by hand: (3 ^ 4) ^ ¼   =   3 ^ (4 x ¼) = 3 ^ 1   = 3   (when you take a power to a power, multiply the exponents.)

or, do it by calculator. one way of finding the fourth root is to use ^ (1/4)
