The 6% state income tax on a 42'000 salery​
Romashka [77]

Answer:

well, simply, it would be $2520.

in reality, an income tax does not work that simply. income taxes are figured using brackets, where (just making up numbers) the first $15000 might be taxed at 2%, earnings between $15,001 to $30,000 are taxed at 4%, and so on.

Thus, without knowing the tax tables to know the different rates and brackets, it's impossible to give an answer.

But in straight math terms, 6% of $42,000 is $2520

42000×.06= 2520

Simplify the expression. What classification describes the resulting polynomial? (3x^2-11x-4)-(2x^2-x-6)
Gnoma [55]

The expression can be simplified to a polynomial of degree 2.

x^2 - 10x + 2

<h3>How to simplify the expression?</h3>

Here we have the expression:

(3x^2 -11x - 4) - (2x^2 - x - 6)

We can directly simplify this by taking the variable as common factor:

(3 - 2)*x^2 + (-11 + 1)*x + (-4 + 6)\\\\x^2 - 10x + 2

This is a polynomial, as you can see, the maximum exponent is 2, so the degree of the polynomial is 2.

Consider a game in which a player rolls a number cube to determine the number of points earned. If a player rolls a number great
zhannawk [14.2K]
The probability of rolling any specific number is 1/6. The expected number of points is found from:
E(points) = (1/6 * -1) + (1/6 * -2) + (1/6 * -3) + (1/6 * 4) + (1/6 * 5) + (1/6 * 6)
             = 9/6 = 1.5 points

F(x)=2(3-x),find f(-7)
Sauron [17]

Answer:

f(-7) = 20

Step-by-step explanation:

Given:

f(x) = 2(3 -x)

Solving for f(-7):

f(-7) = 2(3 -(-7)) \\ f(-7) = 2(3 +7) \\ f(-7) = 2(10) \\ f(-7) = 20
