I believe this this the function.

$f(x) = {5}^{x - 5}$

then

$f(x) = {5}^{2 - 5}$

then

$f(x) = {5}^{ - 3}$

then

$y = \frac{1}{125}$

Find the value of the variable if P is between J & K. <br><br> JP = 2x ; PK = 7x ; JK = 27

Nana76 [90]

J ---- P --- K

JP = 2x
PK = 7x
JK = 27

2x + 7x = 27
9x = 27
x = 27/9
x = 3

The value of P is 3.

JP = 2x = 2(3) = 6
PK = 7x = 7(3) = 21

The sum of the lengths of any two sides of a triangle must be greater than the third side. If a triangle has one side that is 8

julsineya [31]

Good afternoon,

First side= 8cm
Third side= x
Second side= 2x-4

We know that the sume of the lenghts of any two sides must be greater than the third side, so:

$Second \,\,\,\,side+Third\,\,\,\,side>First\,\,\,\,side \\ 2x-4 + x >8 \\ 3x>12 \\ x>4
$

<span>Answer: Third side= x ; where: x>4 or (4,+infinity)
Second side= 2x-4 ; </span><span> where: x>4 or (4,+infinity)</span>
