Kim earned $19,000 last year. If the first $10,000 is taxed at 9% and income above that is taxed at 19%, how
much does Kim owe in tax?

$2,610

Step-by-step explanation:

total money earned: $19,000

she was taxes 9% on the first $10,000 which is equal to:

$900 in taxes for the first $10,000

then the rest (19,000 - 10,000 = 9,000) was earned above the first 10,000, which means that is taxed 19%. Thus, 19% out of 9,000 is equal to:

$1,710 in taxes for the $9,000 earned after the first $10,000

She owes in taxes a total of:

$2,610

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)

false
