Answer:

f(-6) = -2

Step-by-step explanation:

plug in k value (-6)

f(-6) = -6/2 + 1

theres two ways to solve for this

one way:

convert the whole number 1 to an improper fraction

f(-6) = -6/2 + 2/2

combine like terms

f(-6) = -4/2

divide -4 by 2

f(-6) = -2

second way:

divide -6 by 2

f(-6) = -3 + 1

combine like terms

f(-6) = -2

either way you get the same answer

use whichever is easiest for you

The combined height of one for tree and one pine tree is 21 meters. The height of 4 for trees stacked on top of each other is 24

slamgirl [31]

Answer:

The height of the fir tree is 9 meters tall and the pine tree is 12 meters.

Step-by-step explanation:

Given:

Note :→ there is a mistake it is fir tree not for tree.

The combined height of one fir tree and one pine tree is 21 meters.

The height of 4 fir trees stacked on top of each other is 24 meters taller than one pine tree.

Now, to find how tall are the types of trees.

Let the height of one fir tree be $x$ .

And the height of one pine tree be $y$ .

So, the combined height of one fir tree and one pine tree:

$x+y=21.$

$y=21-x.$ .........( 1 )

Now, as given the height of 4 for trees stacked on top of each other is 24 meters taller than one pine tree:

$4x=y+24.$

Putting the value of equation (1) in the place of $y$ :

$4x=21-x+24$

Adding both the sides $x$ we get:

$5x=21+24.$

$5x=45.$

Dividing both the sides by 5 we get:

$x=9\ meters.$

So, the height of one fir tree = 9 meters.

Now, putting the value of $x$ in equation (1) we get:

$y=21-9$

$y=12\ meters.$

Thus, the height of one pine tree = 12 meters.

Therefore, the fir tree is 9 meters tall and the pine tree is 12 meters tall.

Identify the maximum of the graph below. Type your answer by filling in the blanks below

nevsk [136]

Answer:

The maximum point of this function is (5,4).

Step-by-step explanation:

The maximum of a function is the maximum value that it can take.

Seeing the graph we can say that the maximum value of y occurs at x = 4. Here y = 5 corresponds to this value of x.

Therefore, the maximum point of this function is (5,4).

I hope it helps you!

If f(a) = K, then which of the following must be true? f(K) = a f -1(K) = a f -1(a) = K

Inessa05 [86]

Answer:

Step-by-step explanation:

given that f(a) = K

we have the options of

f(K) = a

f ⁻¹ (K) = a

f ⁻¹ (a) = K

Where f ⁻¹ denotes an inverse function.

If f(a) = K, then its reciprocate, f ⁻¹ (K) = a

because it is essentially undoing the original equation
