If h(x) = 5 + x and k(X) =. 1/x which expression is equivalent to (kon)(x)?

Answers

Answer 1
Answer:

Answer:

(5+x)/x

Step-by-step explanation:

Given

h(x)= 5+x

k(x)= 1/x

(koh)(x)=?

Here you multiply

1/x( 5+x)

5/x +x/x

5/x+1 or

5/x +x/x

(5+x)/x
Answer 2
Answer:

For this case we have the following functions:

h (x) = 5 + x\nk (x) = \frac {1} {x}

We must find (k_ {0} h) (x):

By definition of compound functions we have to:

(k_ {0} h) (x) = k (h (x)

So:

k (h (x) = \frac {1} {5 + x}

Finally:

(k_ {0} h) (x) = \frac {1} {5 + x}

Answer:

(k_ {0} h) (x) = \frac {1} {5 + x}

Answer:

$29000 with a margin of error of $5000

Step-by-step explanation:

We have that the midpoint between the given values ​​is

(X1+X2) / 2 = ($34000+$24000)/2 = $29000

We have that the midpoint between the given values ​​would be

(X2-X1)/2=($34000-$24000)/2=$10000/2=$5000

So I can write that approach as $29000 with a margin of error of $5000

The equation of the line of best fit of a scatter plot is y = 7x − 9. What is the slope of the equation?−9, −7, 7, 9

Answers

Answer:

Slope m = 7.

Step-by-step explanation:

Given :  y = 7x − 9.

To find : What is the slope of the equation.

Solution : We have given that y = 7x − 9.

On comparing with y = mx + b

Where, m slope of the line and b = y intercept.

Then slope of y = 7x − 9.

m = 7 and y intercept = -9.

Therefore, Slope m = 7.
I love math. Well the formula is y=mx+b. the slope is m so the answer is 7
