Which function is the inverse of f(x)=4x-1?

Answers

The function  f⁻¹(x) = x/4 + 1/4 is the inverse of f(x)=4x-1

What is a function?

The function is a type of relation, or rule, that maps one input to specific single output.

In mathematics, a function is an expression, rule, or law that describes the relationship between one variable (the independent variable) and another variable (the dependent variable). In maths and the physical sciences, functions are indispensable for formulating physical relationships.

The function is given as f(x)=4x-1

To determine the inverse of a function, switch the places of x and y (or f(x)).

f(x) = 4x - 1

y = 4x - 1

Switch the variables;

x = 4y - 1

Now, convert the equation back into y = mx + b form.

x + 1 = 4y

y = x/4 + 1/4

f⁻¹(x) = x/4 + 1/4

mrs. west is 14 years younger than her aunt. if mrs. west’s age in years is as much below 60 as her aunt’s age is over 40, how old is each?

Answers

Mrs. west is [tex]14[/tex] years younger than her aunt. if mrs. west’s age in years is as much below [tex]60[/tex] as her aunt’s age is over [tex]40[/tex], So, Mrs. West is [tex]43[/tex] years old, and her aunt is [tex]57[/tex] years old.

Let's represent Mrs. West's age as W and her aunt's age as A.

Given that Mrs. West is [tex]14[/tex] years younger than her aunt, we can write the equation:

[tex]W=A-14[/tex]

Also, it's given that Mrs. West's age is as much below [tex]60[/tex] as her aunt’s age is over [tex]40[/tex] . This can be represented as:

[tex]W=60-(A-40)[/tex]

Simplify the equation:

[tex]W=60-A+40\\W=100-A[/tex]

Now, we have two equations for [tex]W[/tex]:

[tex]W=A-14\\W=100-A[/tex]

Since both equations equal [tex]W[/tex], we can set them equal to each other:

[tex]A-14=100-A[/tex]

Now, solve for A:

[tex]A+A=100+14\\2A=114\\A=57[/tex]

Now, plug the value of [tex]A[/tex] into either equation to find [tex]W[/tex]:

[tex]W=57-14\\W=43[/tex]

So, Mrs. West is [tex]43[/tex] years old, and her aunt is [tex]57[/tex] years old.

In certain county, the number of charter schools is 4vless than twice the numbervof alternative schools. We know that there are 48 charter schools in the county. How many alternative schools are in the county?

Answers

Let us assume that the number of alternative schools in the county are x in number.

It is given that the number of charter schools is 4 less than twice the number of alternative schools. So we can write, the number of charter schools is 4 less than twice of x. In equation form this can be written as:

Number of Charter Schools = 2x - 4

It is given that number of charter schools is 48. So we can write:

48 = 2x - 4
2x = 52
x = 26

x was the number of alternative schools. Therefore, there are 26 alternative schools in the county.
1. Let's call the number of carter school: "x" and "y" the number of alternative school.  Then, you have that: 
 - The number of charter schools is 4 less than twice the number of alternative schools.
 - There are 48 charter schools in the country.
 2. So, you have:
 x=2y-4  (i)
 x=48  (ii)
 3. Then, when you substitute x=48 into the equation (i), you obtain:
 x=2y-4
 48=2y-4
 4. Now, you must clear "y, as below:
 48+4=2y
 2y=52
 y=52/2
 y=26

 How many alternative schools are in the county? The answer is: There are 26 alternative schools.

A gardener is installing a circular garden. The circumference of the circle 132 feet. What radius should he use to layout the circle if he uses p=22/7?

The radius is feet.

Answers

C = 2πr
132 ft = 2(22/7)r
r = (132 ft)*7/44 = 21 ft

The radius is 21 feet.

Given that the garden should be in a circular shape.

And the circumference of the circle would be, C = 132 feet.

It says to find the radius of the circular garden, r = ?

We know the formula for Circumference of the circle is given as follows :-

Circumference of circle = 2π x radius

C = 2·π·r

Hint:- It says to use pi = 22/7.

[tex] 132=2*\frac{22}{7}*r \\\\
132=\frac{44}{7}*r \\\\
r=132*\frac{7}{44} \\\\
r= \frac{924}{44} \\\\
r= 21 \;feet [/tex]

Hence, Radius would be r = 21 feet.

Answers

The second integer is greater than the first integer

Answer:

c)The second integer is greater than the first integer

Step-by-step explanation:

In mathematics, a number line can be defined as a straight line with numbers placed at equal intervals or segments along its length.

A number line can be extended infinitely in any direction and is usually represented horizontally, with 0 in the middle and negative numbers on the left and positive numbers to the right of zero.

Thus a number line can be used to represent both positive and negative rational numbers as well as integers.

The numbers to the left are less than that to the right

Hence here the option c) is right

Find all integer solutions to the pair of congruences (if any) x ≡ 17 (mod 23) 70x ≡ 3 (mod 93).

Answers

First, note that [tex]93=3\times31[/tex], which gives

[tex]70x\equiv3\pmod{93}\implies\begin{cases}70x\equiv3\equiv0\pmod3\\70x\equiv3\pmod{31}\end{cases}[/tex]

so in fact we're dealing with the system

[tex]\begin{cases}x\equiv17\pmod{23}\\70x\equiv0\pmod3\\70x\equiv3\pmod{31}\end{cases}[/tex]

Now, 3, 23, and 31 are relatively prime, so we can use the Chinese remainder theorem. But before we do that, we need to rework and ultimately eliminate the coefficients of [tex]x[/tex].

From the second equivalence, it follows immediately [tex]x[/tex] is some multiple of 3; this is because [tex]70x[/tex] is divisible by 3, but 3 doesn't divide 70, so it must divide [tex]x[/tex].

For the third equivalence, we can write [tex]70x=62x+8[/tex]. Then modulo 31, we have that [tex]62x\equiv0[/tex], which leaves us with [tex]8x\equiv3\pmod{31}[/tex]. We want a congruence of the form [tex]x\equiv\cdots[/tex], and to get that we can multiply [tex]8x[/tex] and 3 by the inverse of 8 modulo 31.

To find this inverse, we solve for [tex]y[/tex] in the relation

[tex]8y\equiv1\pmod{31}[/tex]

by using the Euclidean algorithm, or making just making the observation that [tex]8\times4\equiv32\equiv1\pmod{31}[/tex], so [tex]8^{-1}\equiv4\pmod{31}[/tex]. Distributing 4 across the third equivalence in our system gives [tex]x\equiv4\pmod{31}[/tex].

So to recap, we now have

[tex]\begin{cases}x\equiv17\pmod{23}\\x\equiv0\pmod3\\x\equiv12\pmod{31}\end{cases}[/tex]

and we're ready to use the CRT.

As a starting point, let's take

[tex]x=(17)+(23)+(23)=63[/tex]

It's clear that taken modulo 23, the latter two terms vanish and we have a remainder of 17, as desired. 63 is already a multiple of 3, but just to avoid doing more work later, let's multiply each term by 3 anyway to keep getting a remainder of 0:

[tex]x=(17\times3)+(23\times3)+(23\times3)=146[/tex]

Now multiply the first two terms by 31 to make sure they vanish when taken modulo 31. Meanwhile, [tex]23\times3\equiv69\equiv7\pmod{31}[/tex], but we want to get 12, so we would multiply this term by the inverse of 7 mod 31, and again by 12.

We can make a quick observation that [tex]7\times9=63=31\times2+1[/tex], so [tex]7^{-1}\equiv9\pmod{31}[/tex]. Alternatively, you can use the Euclidean algorithm to find this inverse. Either way, we get

[tex]x=(17\times3\times31)+(23\times3\times31)+(23\times3\times9\times12)=11,172[/tex]

So we're told that

[tex]x=11,172+(23\times3\times31)k=11,172+2139k[/tex]

is our solution set, where [tex]k\in\mathbb Z[/tex]. We can "simplify" this slightly by finding the least positive residue modulo the product of our moduli, which would be

[tex]11,172\equiv477\pmod{2139}[/tex]

so we end up with

[tex]x=477+2139k[/tex]

for integers [tex]k[/tex].

what are the slope and why intercept shown on the graph below

Answers

Hello!

Let's start by finding the slope of the line. You can calculate the slope by dividing the change in y-values by the change in x-values using the following formula:

[tex] \frac{ y_{1}- y_{2} }{ x_{1} - x_{2} } [/tex]

The plotted coordinates are (0, 5) and (4, -5); let's plug those into the formula:

[tex] \frac{5(-5)}{0-4} [/tex]

Simplify:

[tex] \frac{5+5}{-4} [/tex]

[tex] \frac{10}{-4} [/tex]

[tex] \frac{-5}{2} [/tex]

The slope is [tex] \frac{-5}{2} [/tex].

Now, the y-intercept is where the line intersects the y-axis, or when x equals 0. x equals 0 when y equals 5, so the y-intercept is 5.

I hope this helps!
Hi there! The formula for finding the slope is y2 - y1/ x2 - x1, where the first x and y-coordinates are subtracted from the second x and y-coordinates. We have the two points on the graph marked. We will use (0, 5) and (4, -5) in this case. Here are the numbers that represent each:

y2 = -5
y1 = 5
x2 = 4
x1 = 0

Let's subtract. -5 - 5 is -10. 4 - 0 is 4. -10/4 is -2 1/2 in simplest form or -5/2 as a mixed number. We found the slope. The y-intercept is where the line crosses, where the x-axis is 0. In this case, we can see by the point given out that the slope intercept is 5. There. The slope is -5/2 and the slope-intercept is 5. The answer is B.
