Consider a function f(x) such that f(5x) =x-5/5x-1. Find f(x) and hence write down the domain of f(x).
Answer:
The domain of [tex]f(x)[/tex] is [tex]Dom \{f(x)\} = \mathbb{R}-\{1\}[/tex].
Step-by-step explanation:
Let [tex]f(5\cdot x ) = \frac{x-5}{5\cdot x-1}[/tex], which is rearranged by algebraic means:
1) [tex]f(5\cdot x ) = \frac{x-5}{5\cdot x-1}[/tex] Given
2) [tex]f(5\cdot x) = \frac{x\cdot 1 - 5}{5\cdot x -1}[/tex] Modulative property
3) [tex]f(5\cdot x) = \frac{5^{-1}\cdot (5\cdot x)-5}{5\cdot x -1}[/tex] Existence of multiplicative inverse/Associative and commutative properties.
4) [tex]f(x) = \frac{5^{-1}\cdot x - 5}{x-1}[/tex] Composition of functions.
5) [tex]f(x) = \frac{(5^{-1}\cdot x-5)\cdot (5\cdot 5^{-1})}{x-1}[/tex] Existence of multiplicative inverse/Associative property.
6) [tex]f(x) = \frac{(x-25)\cdot 5^{-1}}{x-1}[/tex] Commutative, associative and distributive properties/[tex]a\cdot (-b) =-a\cdot b[/tex]/Definition of subtraction
7) [tex]f(x) = (x-25)\cdot [5^{-1}\cdot (x-1)^{-1}][/tex] Definition of division/Associative property
8) [tex]f(x) = (x-25)\cdot (5\cdot x -5)^{-1}[/tex] [tex]a^{c}\cdot b^{c} = (a\cdot b)^{c}[/tex]/Distributive property/[tex]a\cdot (-b) =-a\cdot b[/tex]/Definition of subtraction
9) [tex]f(x) = \frac{x-25}{5\cdot x - 5}[/tex] Definition of division/Result
The domain of a polynomial-based rational function consists in all values of the real set except values where denominator equals zero. The value of [tex]x[/tex] such that rational function becomes undefined is:
1) [tex]5\cdot x - 5 = 0[/tex] Given
2) [tex]5\cdot (x-1) = 0[/tex] Distributive property
3) [tex][5\cdot (x-1)]\cdot 5^{-1} = 0\cdot 5^{-1}[/tex] Compatibility with multiplication
4) [tex](x-1)\cdot (5\cdot 5^{-1}) = 0[/tex] Commutative and associative properties/[tex]a\cdot 0 = 0[/tex]
5) [tex]x-1 = 0[/tex] Existence of multiplicative inverse/Modulative property
6) [tex]x+[1+(-1)] = 1+0[/tex] Compatibility with addition/Commutative and associative properties
7) [tex]x = 1[/tex] Existence of additive inverse/Modulative property/Result
Hence, the domain of [tex]f(x)[/tex] is [tex]Dom \{f(x)\} = \mathbb{R}-\{1\}[/tex].

Answer:
it is attached 18sqrt3
Step-by-step explanation:
this is a 30 60 90 triangle which if u follows the rules of leg measurements u will find that leg a is always xsqrt3 and since x is 2x, that means ur x is 18 given that c is twice x for it's leg so now that x is 18 slap that on for x of leg a to get 18sqrt3
For the graph x = 1 find the slope of a line that is perpendicular to it and the slope of a line parallel to it.
Explain your answer with two or more sentences
Answer:
Step-by-step explanation:
Firstly we know that in geometry parallel lines have the same slope
[tex]m_1=m_2[/tex]
and ,
perpendicular lines have the slope denoted by the formula
[tex]m_1m_2=-1[/tex].
Secondly ,
x = 1 is a line that is parallel to the y-axis, and any line parallel to the y-axis has undefined slope.
and the slope of a line perpendicular to x = 1 would be parallel to the x-axis and any line parallel to the x-axis has the slope of zero.
Slope for parallel line is undefined and slope for perpendicular line is zero.
What is slope?The slope or gradient of a line is a number that describes both the direction and the steepness of the line.
Given:
graph equation, x=1
The slope for parallel line is
m1 = m2
and, the slope for perpendicular lines is
m1 * m2 =-1
As, x = 1 is a line is parallel to the y-axis, and line parallel to the y-axis has undefined slope.
Also, the slope of a line perpendicular to x = 1 would be parallel to the x-axis.
So, line will have the slope zero.

Answer:They are 600 feet apart from each other
Step-by-step explanation:
Answer:
600
Step-by-step explanation:
the 200 since its below the surface it would become negitive and 400 - -200 would turn into 400 + 200 and that would be 600 :)

find a number that is exactly halfway between 1 and 27
Answer:
14
Step-by-step explanation:
A number that is exactly halfway between 1 and 27 is the middle number
In other words, we want to find the median between 1 and 27
Median = (x + y) / 2
Let
x = 1
y = 27
Median = (x + y) / 2
= (1 + 27) / 2
= 28/2
= 14
Therefore, the number between 1 and 27 is 14

What is a number line?Integers are arranged at equal intervals along horizontal straight lines called number lines. A number line can be used to represent every number in a series. The endpoints of this line go on forever. Some will have a defined beginning and end. It refers to those as closed number lines. Number lines might be alternatively left empty or blank. A number ladder is a vertical number line.
We have been given number line going from negative 4 to positive 4.
Negative 2.4, negative 1.5, negative 2 and one-fourth, negative 3, negative 1 and one-eighth
For this we need to remember the number line, we have that that:
-3 <-2.4 < -2 < 1/4 <-1.5 < -1 < -1 1/8< 0
We go from the big negative numbers, to the small negative numbers, the zero, the small positive numbers, the big positive numbers.
Therefore, the numbers from least to greast the correct options are:
-3, -2.4, -2 1/4, -1.5, -1 1/8

Two students are 1 foot apart on a straight path. Each student starts walking away from the other at the same moment. The first student walks at a rate of 3 feet per second, and the second student’s rate is 1.5 times the first student’s rate. If x represents seconds, which equation can be used to determine how long it will take for the students to be a total of 28 feet apart?
Answer:
3x + 4.5x + 1 = 28
3.6 seconds
Step-by-step explanation:
Initial distance apart = 1 foot
Student A:
Walk rate = 3 ft per second
Student B:
1.5*3 = 4.5 ft per second
How long it will take to be a total of 28 feets apart
Distance = speed * time
Let time = x in seconds
Student A distance = 3x
Stident B distance = 4.5x
Initial distance = 1 foot
3x + 4.5x + 1 = 28
7.5x = 28 - 1
7.5x = 27
x = 27/ 7.5
x = 3.6 seconds
