=
Step-by-step explanation:
means the inverse function
to find an inverse function, flip the x and y variables and solve for y
f(x) = 5x^3 - 6
y = 5x^3 - 6
x = 5y^3 - 6
x + 6 = 5y^3
(x + 6)/5 = y^3
= y

=0.5
Answer:
180
Step-by-step explanation:
Given the ratio = 7 : 3 : 2 = 7x : 3x : 2x ( x is a multiplier ), then
7x = 2x + 75 ( Natasha gets 75 more sweets than Henry )
Subtract 2x from both sides
5x = 75 ( divide both sides by 5 )
x = 15
Thus
total number of sweets = 7x + 3x + 2x = 12x = 12 × 15 = 180
Answer:
Shad's cost per use will be $ 2.80.
Step-by-step explanation:
Since Shad Yarbrough wants to consider the cost per use of a high-end desk top computer he is considering for his web site business, and the computer costs $ 1,750 and has a life expectancy of four years, if Shad feels he would use the computer three days a week, on average, to determine what is Shad's cost per use, the following calculation must be performed:
Weeks per year = 52
52 x 4 = 208
208 x 3 = 624
1750/624 = X
2.80 = X
Thus, Shad's cost per use will be $ 2.80.
