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 <u>9 meters</u> tall and the pine tree is <u>12 meters</u>.

Step-by-step explanation:

Given:

Note :→ there is a mistake it is <u>fir tree</u> 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 $y$ :

$4x=21-x+24$

<em>Adding both the sides $x$ we get:</em>

$5x=21+24.$

$5x=45.$

<em>Dividing both the sides by 5 we get:</em>

$x=9\ meters.$

<em>So, the height of one fir tree = 9 meters.</em>

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

$y=21-9$

$y=12\ meters.$

<em>Thus, the height of one pine tree = 12 meters.</em>

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

Which absolute value function, when graphed, will be wider than the graph of the parent function, f(x) = |x|?

Iteru [2.4K]

There is no absolute value function when graphed, will be wider than the graph of the parent function f(x) = |x|

<h3>What is an absolute value function?</h3>

An absolute value function is a function such that,

$|x|=-1 when x\geq 0 and |x|=1 when x\leq 0$

For the given example,

We have been given a parent function f(x) = |x|

We need to find the absolute value function, when graphed, will be wider than the graph of the parent function.

Consider the graph of all absolute value functions.

The graph of f(x) = |x| + 3 is represented blue color.

The graph of f(x) = |x − 6| is represented green color.

The graph of f(x) = |x| is represented red color.

The graph of f(x) = 9|x| is represented violet color.

From this graph, we can observe that,

f(x) = |x| + 3 is as wise as the parent absolute value function f(x) = |x| translated up by 3 units.

Similarly, the function f(x) = |x - 6| is as wise as the parent absolute value function f(x) = |x| translated right by 6 units.

This means, there is no absolute value function when graphed, which will be wider than the graph of the parent function f(x) = |x|
