Answer:
$4.84
Step-by-step explanation:
County A: Multiply the price by the sales tax to find out how much money the sales tax will add. Remember to convert percent to decimal!
$75 * 0.0725 = $5.4375
Add the original price and the sales tax.
$75 + $5.4375 = $80.4375
County B: Multiply the price by the sales tax to find out how much money the sales tax will add. Remember to convert percent to decimal!
$70 * 0.08 = $5.6
Add the original price and the sales tax.
$70 + $5.6 = $75.6
Then take the difference.
80.4375 – 75.6 = 4.8375
Round to the nearest hundredth: $4.84
Answer:
The quadratic equation is 
Step-by-step explanation:
The quadratic equation form f(x) = a ( x- α) (x-β)
The roots are −6 and 4 and whose leading coefficient is 3.
the quadratic equation is f(x) = 3 ( x- (-6)) (x-4) = 
The quadratic equation is 
<u>Final answer</u>:-
The quadratic equation is
Answer:
14
Step-by-step explanation:
substitute -2 into x in the equation
f(x) = -x^2 - 9x
f(-2) = -(-2)^2 - 9(-2)
f(-2) = 14 after calculation
