Find the amount of tax and tax rate. Round to nearest hundredth of a percent. COST OF ITEM: $130 SELLING PRICE: $142.28 Tax amount ? Tax rate ?

To find the sales tax rate, take the final (142.28) minus the initial (130) divided by the initial (130) and multiply it all by 100.

$12.28 / 130 = 0.0945

0.09446 * 100 = 9.45%

(- 1, 0 )

step-by-step explanation:

an x- intercept is where the function crosses the x- axis.

to find the x- intercept/s look for the value of x when f(x) = 0

from the given table there are 3 values of x where f(x) = 0

when x = - 1, x = 2, x = 3

the one that is listed is (- 1, 0 )
