The function f(x)=50x+6500 represents the amount of money in a bank account over time. The function g(x)=−25x+9300 represents the amount of money in another account over time. Write a rule for the total amount of money in the two accounts over time.

if you mean

then it's c. 8, -7/3

but if you mean

then it is

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)
