Help me please The total cost f(x), in dollars, for renting a moving van for a week and driving it x miles is shown below: f(x) = 90 + 0.13x What is the value of f(200), and what does f(200) represent?

f(200) = 116

Step-by-step explanation:

Given the function f(x) = 90 + 0.13(x), and f(200), this means that you have to solve the function by plugging in 200 substituting the x, and solve,

f(200) = 90 + 0.13(200)

f(200) = 90 + 26

f(200) = 116

The f(200) represents the total cost in dollars when driving for 116 miles.

step-by-step explanation:

x =±sqrt(1/3)

step-by-step explanation:

x+4/6x=1/x

multiply each side by 6x to get rid of the fractions

6x*(x+4/6x)=1/x*6x

distribute

6x^2 +4 = 6

subtract 4 from each side

6x^2 +4-4 = 6-4

6x^2 =2

divide by 6

6x^2/6 = 2/6

x^2 = 1/3

take the square root of each side

sqrt(x^2) = ±sqrt(1/3)

x =±sqrt(1/3)
