Answer with explanation:

The given function is,

f(x)=x

We can Write it as,replacing f(x) by y

→y=x ------------------(1)

When , f(x) is replaced by $\frac{-f(x)}{2}$ in the above equation, the above equation reduces to

$\frac{-f(x)}{2}=x\\\\ f(x)= -2 x$

Similarly, Replacing f(x) by y in this equation also,the equation becomes

→→ y = - 2 x ---------------(2)

Plotting the graph of , Line 1 and Line 2

Now, when line 1 is reflected either through , x axis or y axis, the equation of line 1 becomes

→→y= -x

As,→ if there would have been vertical stretch, distance between origin and points on the curve would have been Larger.

But , →why compression because distance between axis of reflection and curve which has been compressed, that is , y=-2 x, has reduced.

Option D: Horizontal reflection over y-axis and horizontal compression

Step-by-step explanation:

The sum of interior angles in a rectangle is 360°

98 + 98 + 98 + 2x = 360

294 + 2x = 360

2x = 66°

x = 33

The outside edges of the walkway form a rectangle whose length and width are proportional to the sides of the garden, increased

Allisa [31]

The length and the width of the outside edge of the garden will be ( 6x + 12 ) and ( 9x + 6 ) respectively.

<h3>What is the scale factor?</h3>

In mathematics, a scale factor is the proportion of related dimensions of an object to a description of that object.

Given that:-

The outside edges of the walkway form a rectangle whose length and width are proportional to the sides of the garden, increased by a scale factor of 3. the sides of the garden are (2x+4) and (3x+2)

The length and width of the outside edge will be:-

The sides are Dilated by factor 3 so the edges of the rectangle will be calculated as;-

Length = 3 ( 2x+4 ) = 6x + 12

Width = 3 ( 3x+2 ) = 9x + 6

Therefore the length and the width of the outside edge of the garden will be ( 6x + 12 ) and ( 9x + 6 ) respectively.

How many whole numbers are there with not more than 4 digits IF YOU PUT A LINK OR UNHELPFUL ANSWER I WILL REPORT I WILL GIVE BRA

belka [17]

Answer:

There are 9,999 positive whole numbers with 4 or less digits or less and one whole number which is neither positive nor negative.

This gives us 9,999+9,999+1 or 19,999 , whole numbers composed of 4 digits or less.

Solve the proportion. a. 4/x = 9 b. 7.5/26 = 75/p

lina2011 [118]

<u>ANSWER: </u>

The values of x and p after solving given equations are 0.445 or $\frac{4}{9}$ and 260 respectively..

<u>SOLUTION: </u>

Given, two proportions are $\frac{4}{x}$ =9 and $\frac{7.5}{26} = \frac{75}{p}$

We need to solve the given two proportions.

Let us solve the first proportion, $\frac{4}{x}$ = 9

$\frac{4}{x} = \frac{9}{1}$

On cross-multiplication, we get

4 $\times$ 1 = 9x

4 = 9x

x = $\frac{4}{9}$

x = 0.445

Now, let us solve the second proportion $\frac{7.5}{26} = \frac{75}{p}$

$\frac{\frac{75}{10}}{26}=\frac{75}{p}$

$\frac{75}{10 \times 26} = \frac{75}{p}$

$\frac{1}{260} = \frac{1}{p}$

On cross-multiplication, we get

p = 260

Hence, the values of x and p after solving given equations are 0.445 and 260 respectively.
