Hey there! 

First: Distribute the problem 

Like
:  4(k) and 4(6) (other half) -4(2k) and 4!) 

Problem become: -5k + 4k + 24 = -8k + 1

Second: Combine your like terms 

Like: -5k + 4k + 24 = -8k - 4

Problem becomes: -k + 24 = -8k - 4

Third: add the value 8k to your sides

Like: -k + 24 + 8k \\ \\ =  -8k - 4 + 8k

Problem becomes: 7k + 24 = -4

Fourth: subtract by 24  on each of your sides

Like: 
7k + 24 - 24 \\ \\  = -4 - 24

Problem becomes: 7k = -28

Fifth: divide both sides by 7

Like: \frac{7k}{7} =  \frac{-28}{7}

Answer: k =-4

Good luck on your assignment and enjoy your day!

-5k + 4(k + 6) = -4(2k + 1)        Given
-5k + 4k + 24 = -8k - 4            Distributive Property
          -k + 24 = -8k - 4            Combine like terms
         7k + 24 = -4                   Add 8k to both sides
                 7k = -28                 Subtract 24 from both sides
                   k = -4                   Divide both sides by 7

Answer:
k = -4

Hope this helps!

Find the probability. An IRS auditor randomly selects 3 tax returns (without replacement) from 47 returns of which 5 contain err
grin007 [14]
Number of returns = 47
Number of returns that contain errors = 5
Number of returns that does not contain error = 47 - 5 = 42

P(selecting none that contains error in the unreplaced selection) = 42/47 x 41/46 x 40/45 = 68880 / 97290 = 0.708

option C is the correct answer.

Find the inverse function
Troyanec [42]

The inverse of the function is f(x) = x^{3} + 8

In order to find the inverse of any function, start by switching the f(x) and x. Then solve for the new f(x). The result will be the inverse function. The work is below for you.

f(x) = \sqrt[3]{x - 8} ----> Switch f(x) and x

x = \sqrt[3]{f(x) - 8} ----> Cube both sides

x^{3} = f(x) - 8 ----> Add 8 to both sides

f(x) = x^{3} + 8

Work out the value of angle x
Alexus [3.1K]

well, it's isosceles so use base angles theorem

the top angle is also x

90 + 2x = 180

subtract 90 from both sides

2x = 90

divide both sides by 2

x = 45 degrees

Find the missing angle.
Sphinxa [80]

Answer:

m\angle XYV=135^{\circ}

Step-by-step explanation:

Notice that m\angle XYV=m\angle XYW+m\angle VYW.

The diagram already marks m\angle VYW=80^{\circ}, so we just need to find m\angle XYW.

\angle TYU and \angle XYW are vertical angles, which means they are equal in measure.

Therefore,

m\angle TYU=m\angle XYW=6x+7

Since there are 180^{\circ} on each side of a line, we have the following equation:

m\angle XYW+m\angle VYW+m\angle UYV=180^{\circ},\\6x+7+13+4x+80=180,\\10x+20=100,\\10x=80,\\x=8.

Plugging in x=8, we have:

m\angle XYW=6(8)+7=55^{\circ}.

Therefore,

m\angle XYV=55^{\circ}+80^{\circ},\\m\angle XYV=\fbox{$135^{\circ}$}.
