Kathy is going to buy a book at the bookstore for $9.45. The tax rate is 10%. What is the total cost Kathy would have to pay?

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)

slope= 1

y-inter slope= 0

x       y

o     0

1       1

2     2

ect.
