If Neal and Linda had a combined taxable income of $209,150 and filed their federal income tax with the married filing jointly s

Yuki888 [10]

Answer:

correct option is A. $46840.50

Step-by-step explanation:

given data

taxable income = $209,150

solution

we calculate the tax for income is $209,150

The tax of the taxable income over $208,850 but but not over $372950 is

tax of the taxable income over $208,850 = $47741.50 plus 33% of the amount over $208850

tax = $47741.50 + 33% of ( $209,150 - $208850 )

tax = $47741.50 + 33% of ( $300)

solve it we get

tax = $46840.5

so correct option is A. $46840.50

If the quadratic formula is used to find the solution set of 3x2 + 4x - 2 = 0, what are the solutions?

7nadin3 [17]

Answer:

$x=\frac{-2}{3} \pm \frac{\sqrt{10}}{3}$

Step-by-step explanation:

Compare $ax^2+bx+c$ to $3x^2+4x-2$ .

We have $a=3,b=4,c=-2$ .

The quadratic formula is for solving equations of the form $ax^2+bx+c=0$ and is $x=\frac{-b \pm \sqrt{b^2-4ac}}{2a}$ .

So we are going to plug in our values in that formula to find our solutions,x.

If you want to notice it in parts you can.

Example I might break it into these parts and then put it in:

Part 1: Evaluate $b^2-4ac$

Part 2: Evaluate $-b$

Part 3: Evaluate $2a$

------Let's do these parts.

Part 1: $b^2-4ac=(4)^2-4(3)(-2)=16-12(-2)=16+24=40$ .

This part 1 is important in determining the kinds of solutions you have. It is called the discriminant. If it is positive, you have two real solutions. If it is negative, you have no real solutions (both of the solutions are complex). If it is 0, you have one real solution.

Part 2: $-b=-4$ since $b=4$ .
