nydimaria [60]

The taxable income for this year will be $37,735. Then the correct option is D.

<h3>What is the percentage?</h3>

The amount of something is expressed as if it is a part of the total which is a hundred. The ratio can be expressed as a fraction of 100. The word percent means per 100. It is represented by the symbol ‘%’.

This year, you owed $6,414.95 in federal income tax.

If you are taxed at a net rate of 17%.

Then the taxable income for this year will be given by

\rm Taxable\ income = \dfrac{6414.96}{0.17}\\\\Taxable\ income = 37735.05 \approx 37735

lara31 [8.8K]

Answer:

steps below

Step-by-step explanation:

x⁶ - 7x³ - 8 = (x⁶ + x³) - (8x³ + 8)

                  = x³ (x³+1)-8(x³+1)

                  = (x³ - 2³)(x³ + 1)

                  = (x-2)(x²+2x+4)(x+1)(x²-x+1)

(x-2)(x²+2x+4)(x+1)(x²-x+1) = 0

<u>x= -1 or x = 2</u>   ... roots

or    x²+2x+4=0   or    x²-x+1=0  

x²+2x+4=0

x = (-2±√4-16)/2 = <u>-1 ± √3 i</u>   ... complex roots

x²-x+1=0

x = (1±√1-4)/2 = <u>1/2 ± (√3)i / 2</u>   ... complex roots

<u />

b) P(x) = x⁶ - 7x³ - 8

           = <u>(x-2)(x²+2x+4)(x+1)(x²-x+1)</u>

           = (x+1)(x-2)(x-(-1 + √3 i))(x-(-1 - √3 i)(x-(1/2 + (√3)i / 2))(x-(1/2 - (√3)i / 2))

I got a pic plz help​
tensa zangetsu [6.8K]

Answer:

For the first one, you get x<7.

For the second one, you get x >_ 11

Step-by-step explanation:

For the first one: -2x - 2 > -16

Step 1. Add 2 to both sides.

-2x - 2 +2 > -16 + 2

-2x > -14

Step 2. Divide both sides by -2 and switch the sign

-2x/-2 > -14/-2

x < 7

For the second one: 2x - 1 >_ 21

Step 1: Add 1 to both sides

2x -1 +1 >_ 21 + 1

2x >_ 22

Step 2: Divide both sides by 2

2x/2 >_ 22/2

x >_ 11

hope this helps!
