The absolute value of the inequality is x < 6

Absolute value can be defined as the describing the distance of a number from zero on the number line, without considering direction.

It is also the value of the number with no consideration to it's sign.

Given the inequality;

| | x+4|-7 |< 5 | |

Take the absolute value and expand the bracket

(x + 4) + 7 < 5

expand the bracket

x + 4 + 7 < 5

x + 11 < 5

Make 'x' the subject

x < 5 - 11

x < -6

Take the absolute value

x < 6

Thus, the absolute value of the inequality is x < 6

f ⁻¹( x)= x^2+4 is the inverse of f(x)= [tex]\sqrt{x-4}[/tex]

what is an inverse function ?

An inverse function or an anti function is defined as a function, which can reverse into another function. In simple words, if any function “f” takes x to y then, the inverse of “f” will take y to x. If the function is denoted by 'f' or 'F', then the inverse function is denoted by f-1 or F-1.

write f(x)= [tex]\sqrt{x-4}[/tex] as an equation

y= [tex]\sqrt{x-4}[/tex]

interchange the variables

x= [tex]\sqrt{y-4}[/tex]

solve the equation for y we get

squaring both side ,we have

x^2 = y-4

this implies that

y= x^2 +4

replace y with f ⁻¹( x)  to show the final answer

f ⁻¹( x)= x^2+4

Hence, f ⁻¹( x)= x^2+4 is the inverse of f(x)= [tex]\sqrt{x-4}[/tex]

Answer: 8,938 [tex]\frac{8}{9}[/tex] or 8,938.8889 meters per second

Step-by-step explanation:

     To solve this problem, we will use a process called dimensional analysis (that you have probably done many times without realizing it).

     What is dimensional analysis? Let's say you know there are 12 inches in a foot, and you want to know how many inches are in 2 feet. 12 * 2 = 24 inches in a foot, that's dimensional analysis!

     Here is the process you would take to solve your problem:

➜ If we have the units [tex]\frac{hour}{hour}[/tex], they "cancel" out to become one. This way, we make sure we end up with the correct units, [tex]\frac{meters}{second}[/tex].

➜ We take units we know, such as 3,600 seconds in an hour, and multiply them by the original value until we end up with the measurement we want.

[tex]\displaystyle 20,000\; \frac{miles}{hour}*\frac{1 \;hour}{3,600\; seconds} *\frac{1,609\;meters}{1\;mile}=\frac{20,000*1*1,609\;meters}{3,600\;seconds} =\frac{32,180,000\;meters}{3,600\;seconds} = 8,938.89\; \frac{meters}{second}[/tex]

     In other words;

           8,938.89 meters per second

j = 3

Step-by-step explanation:

Recall the slope formula:

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

Now, simply substitute the values from the question.

[tex]\frac{1}{3} =\frac{-4+3}{j-6}[/tex]

Now, use the cross-multiplication method. (remember, when subtracting negatives, the negative becomes a positive)

[tex]1(j-6)=3(-4+3)[/tex]             Cross Multiplication

[tex]1(j-6)=3(-1)[/tex]                   Simplify

[tex]j-6=-3[/tex]                            Distributive Property

[tex]j=3[/tex]                                     Addition Property

Therefore, j = 3.

The the distance between the school and Nokesville be on the map is 0.7 inches.

What is scaling ?

It is the technique to resize drawing with comparing to actual size of object which uses proportion or ratio. For example, Mapping of earth, drawing prototype of automobiles.

It is given that :

The distance between the school and Target is 4.2 miles and on a map the ratio is 0.5 inches is equal to 3 miles that is :

3 miles = 0.5 inches on map

Now to find the distance between the school and Nokesville be on the map we first find for 1 miles on the map and then multiply it by 4.2 miles :

3 miles = 0.5 inches on map

1  miles = 0.5/3 inches on map

4.2 miles = (0.5/3) x 4.2 inches on map

4.2 miles = 0.7 inches inches on map

Therefore, the the distance between the school and Nokesville be on the map is 0.7 inches.

The answer to the present question is:5x² + 13x - 6 = (5x - 2) (x + 3)

For a polynomial, ax² + bx + c, we want to separate the center term because the sum of these two numbers, whose sum is adequate to the merchandise of the opposite two numbers.

So, here, we'd like to rewrite 13 because the sum of two numbers, whose product is adequate to the opposite two numbers, i.e., 5*(-6) = -30

So, to separate 13, two numbers used here will be: 1 5 and -2, because after we will add 15 and -2 we are going to get 13 and that we will multiply them, then we are going to get

-30.5x² + 13x -6 = 5x² + 15x - 2x - 6

                           = 5x(x + 3) - 2(x + 3)

                             = (5x - 2) (x + 3)

Therefore,  5x² + 13x - 6 = (5x - 2) (x + 3)

If the expression is log₃ 7(2 x-3)², then the expansion of the expression is [[tex]log_{3}[/tex] 7+ [tex]log_{3}[/tex] [tex](2x-3)^{2}[/tex]]

Given that the expression is log₃ 7(2 x-3)².

We are told to find the expansion of the expression.

Logarithmic function is basically the opposite of the exponential function and is denoted by log or ln.

It says that [tex]log_{a} b[/tex]= [tex]log_{x}b /log_{x}a[/tex].

The expression is log₃ 7(2 x-3)².

We know that log mn=log m +log n.

log₃ 7(2 x-3)²=[[tex]log_{3}[/tex] 7+ [tex]log_{3}[/tex] [tex](2x-3)^{2}[/tex]]

Hence if the expression is log₃ 7(2 x-3)², then the expansion of the expression is [[tex]log_{3}[/tex] 7+ [tex]log_{3}[/tex] [tex](2x-3)^{2}[/tex]]

Answer:

y = -2

Step-by-step explanation:

Given equation:

[tex]3(-4y-5)=8y+25[/tex]

Distribute:

[tex]\implies 3 \cdot -4y - 3 \cdot 5=8y+25[/tex]

[tex]\implies -12y - 15=8y+25[/tex]

Add 15 to both sides:

[tex]\implies -12y - 15+15=8y+25+15[/tex]

[tex]\implies -12y =8y+40[/tex]

Subtract 8y from both sides:

[tex]\implies -12y-8y =8y+40-8y[/tex]

[tex]\implies -20y =40[/tex]

Divide both sides by -20:

[tex]\implies \dfrac{-20y}{-20} =\dfrac{40}{-20}[/tex]

[tex]\implies y =-2[/tex]

Now we have to,

→ solve for the required value of y.

Let's solve the problem,

→ 3(-4y - 5) = 8y + 25

→ -12y - 15 = 8y + 25

→ -12y - 8y = 25 + 15

→ -20y = 40

→ y = -40/20

→ [ y = -2 ]

Hence, the value of y is -2.

Answer:

(0, - 9 )

Step-by-step explanation:

x = 2y + 18 → (1)

5x = - 3y - 27 → (2)

substitute x = 2y + 18 into (2)

5(2y + 18) = - 3y - 27

10y + 90 = - 3y - 27 ( add 3y to both sides )

13y + 90 = - 27 ( subtract 90 from both sides )

13y = - 117 ( divide both sides by 13 )

y = - 9

substitute y = - 9 into (1)

x = 2(- 9) + 18 = - 18 + 18 = 0

solution is (0, - 9 )

The logarithmic form of 1/4 = 4⁻¹ is log₄ 4⁻¹ = ₋1.

The fundamental logarithmic function has the notation f(x) = log(r) y = log(x), where a > 0. The exponential function ay = x's inverse is represented by this. The common logarithm (log) or natural logarithm (ln) are examples of log functions (log).

The exponential function of the type aˣ = N can be converted into the logarithmic function logₐN = x. A Napier logarithm table can be used to determine the logarithmic value of any number. Logarithms are often calculated using a base of 10, therefore it is possible to get the logarithmic value of any number.

we have the exponential form as aˣ = N

1/4 = 4⁻¹

now the logarithmic form is:

logₐ N = x

log₄ 4⁻¹ = ₋1

The value of the expression √75 + √125 is 5 (√3 + √5 ).

A number is a fundamental mathematical unit. For counting, measuring, and comparing quantities, we utilize numbers. A set of symbols, or numerals, used to represent numbers is known as a number system.

A square root is a factor of a number that yields the original number when multiplied by itself.

Consider the expression √75 + √125,

Let's assume x = √75 + √125

Now,

75 = 5 × 15 = 5 × 3 × 5

125 = 5 × 25 = 5 × 5 × 5

Therefore,

x = √75 + √125

x = √ [ 5 × 3 × 5] + √ [ 5 × 5 × 5 ]

x = 5√3 + 5√5

x = 5 × [ √3 + √5 ]

x = 5 × [ 1.73 + 2.24 ]

x = 5 × 3.97

x = 19.85

√75 + √125 = 19.85

Hence, the value of √75 + √125 is equal to 19.85.
