Find the input (x) of the function y = 1/4x+ 12 if the output<br> (y) is 6
vagabundo [1.1K]

Answer:

x = -24

Step-by-step explanation:

y = 1/4x+12 (Substitute 6 for y)

6 = 1/4x+12 (Subtract 12 from both sides)

6-12= -6 so its now -6 = 1/4x and since its a fraction you want to multiply both sides by the reciprocal

4*-6 = 1/4x*4 (1/4*4=1 which is 1x or x)

-24 = x

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
