Hi,
Let assume y=x-2, so x=y+2

$f(x-2)=2x-4\\

f(y)=2(y+2)-4\\

f(y)=2y+4-4\\

f(y)=2y\\
$
f(x)=2x

Answer:

10 sides (decagon)

Step-by-step explanation:

You find the perimeter by adding up all the sides of a shape.

side + side + side + side... = perimeter

You know that each side is 4/5 centimeters. You also know that the perimeter is 8 centimeters.

You can set up an equation like this:

4/5 * number of sides = 8

or you can write it in a simpler form as:

4/5x=8

Now solve it like a normal equation:

5 * (4/5x) = (8) * 5

(4x) / 4=(40) / 4

x = 10

So, you know the shape has 10 sides that are 4/5 centimeters each.

What is the possible arrangement for 22 students

$\bf \stackrel{Permutations}{_nP_r=\cfrac{n!}{(n-r)!}}~\hspace{6em}\stackrel{\textit{22 units arranged in groups of 22}}{_{22}P_{22}=\cfrac{22!}{(22-22)!}} \implies _{22}P_{22}=\cfrac{22!}{0!} \\\\\\ _{22}P_{22}=\cfrac{22!}{1}\implies _{22}P_{22}=22!\implies _{22}P_{22}=1124000727777607680000$

Determine whether the representation is proportional.y= -9x

valina [46]

Answer:

Yes it is

Step-by-step explanation:

y=-9x means that for every x value, the y value decreases by 9, so it is proportional because the value of y decreases the same amount each time. For example, if x=1, y=-9. If x=5, y=-45, and so on.
