<h2>Adding Functions</h2>

Example:

(f+g)(x)=f(x)+g(x)

To add this, we can substitute in the functions and combine like terms.

<h2>Solving the Question</h2>

We're given:

  • k(x)=5x-6
  • (k+k)(4)=?

Add <em>k</em> to <em>k</em>:

(k+k)(x) = k(x)+k(x)\\(k+k)(x) = 5x-6+5x-6\\(k+k)(x) = 10x-12

Input <em>x</em> as 4:

(k+k)(4) = 10x-12\\(k+k)(4) = 10(4)-12\\(k+k)(4) = 40-12\\(k+k)(4) = 28

<h2>Answer</h2>

(k+k)(4)=28

(k+k)(4) is equivalent to 28.

<h3>What is function ?</h3>

If we have two non-empty sets X & Y, then each element of X is relative to at least one element of Y. This relation between elements of two sets is called function.

Addition of two functions : If f(x) & g(x) be two functions, then

(f+g)(x) = f(x)+g(x)

<h3>What is the required result ?</h3>

Given, k(x) = 5x-6

Now, Adding function k with k we get,

(k+k)(x) = k(x)+k(x)

           = (5x-6)+(5x-6)

           = 5x-6+5x-6

           = 10x-12

We have to find, (k+k)(4)

∴  (k+k)(4) = (10×4)-12

                = 40-12

                = 28

A sample data set has a mean of 122.3 and a standard deviation of 18.5. Convert a score of 168.4 to a z score and determine if t
shtirl [24]

Answer:

Z=2.49 and this Z-score is “unusual.”

Step-by-step explanation:

To calculate the Z score use the following formula

Z=\frac{x-\mu}{\sigma}

Where

μ is the average

\sigma is the standard deviation

x is the data to which we will calculate the z-score

In this case

\mu = 122.3\\\\\sigma= 18.5\\\\x =168.4

So

Z=\frac{168.4-122.3}{18.5}

Z=2.49

A z-score is unusual if Z> 2 or Z < -2

Finally

Z=2.49 and this Z-score is “unusual.”

One of the angles formed by two intersecting lines measures 30°. What are the measures of the other three angles? i need help AS
lord [1]

Answer: The angles are 30 30, 150, 150

Step-by-step explanation: Two lines intersect means they cross. According to the vertical angle theorem, angles that are across are the same, a line is 180 degrees so it means the angles that make up the supplementary pair add up to 180(180-30=150). So there are 2 150 degree angles and 2 30 degree angles
