The inverse of a function when x = -1 is g^-1(-1) = -5/2

Linear functions are function that has a leading degree of 1. Given the expression below;

g(x) = 2x + 4

Determine the inverse

y = 2x + 4

Replace y with x

x = 2y + 4

Make y the subject of the formula

2y = x - 4

y = (x-4)/2

g^-1(x) = (x-4)/2

Substitute x = -1 into the equation

g^-1(x) = (-1-4)/2

g^-1(-1) = -5/2

Hence the inverse of a function when x = -1 is g^-1(-1) = -5/2

Tim owns 74 socks, the colours of which are unknown.

He does, however, have an additional pair that is white rather than black.

Therefore, it suggests that we are working with the two hues white and black.

The result of dividing the total number of socks by two is:

= 74/2

= 37 socks, two pairs each for black and white.

But let's not forget that Tim has a pair of white socks in addition to his black pair.

The total number of white socks is equal to= 37+1= 38 socks.

Total black sock pairs= 37-1=36 socks.

Last but not least, the question asks us to count the number of single socks rather than pairs.

For white then:

There will be = (38x 2) socks per pair.

= 76 socks

For Black

The individual socks will be = (36 × 2)socks

= 72 socks

We can then deduce that there are 76 individual socks for white and 72 individual socks for black.

The solution would have to be four. Despite the large number of socks in the drawer, there are only three different colours, so if you take four socks, you will undoubtedly find at least one pair that matches.

The density of the material in ounce per liter is 0.1059 ounce per liter.

The ounce per liter conversion selector on this page selects the density measurement unit to convert to starting from ounces per liter (oz/L).

Given that,

Density = 3 grams per fluid ounce

Convert grams to ounce.

1 grams = 0.0353 ounce

Then

Density = 3 * 0.0353 ounce per fluid grams

             = 0.1059 ounce per fluid grams

Convert fluid gram to liter

Density = 0.1059 ounce per 1000 liter

             = 0.0001059 ounce per liter

Hence, the density in ounce per liter is 0.0001059 ounce per liter.

The graph of the system of linear equations is shown in the image below, where the solution is: (3, 1)

The coordinates where x - 2y = 1 intersects the x-axis (horizontal axis) is: (-14, 0)

Given the linear equations:

5x – y = 14 ---> equation 1

x – 2y = 1 ---> equation 2

Rewrite both equations in slope-intercept form as y = mx + b, where b represents the y-intercept of the line and m represents the slope.

5x - y = 14

-y = -5x + 14

y = 5x - 14 (slope is 5 and y-intercept is -14)

x - 2y = 1

-2y = -x + 1

y = 1/2x - 1/2 (slope is 1/2, and the y-intercept is -1/2).

Therefore, the graph of the system of linear equations is shown in the image below, where the solution is: (3, 1)

Using translation concepts, the graph that shows that function f(x) = x with an input of f(x - 3) is given by:

A coordinate plane with a line passing through (negative 2, negative 5), (0, negative 3), and (3, 0).

The input of the function, of f(x - 3), is missing.

A translation is represented by a change in the function graph, according to operations such as multiplication or sum/subtraction either in it’s definition or in it’s domain. Examples are shift left/right or bottom/up, vertical or horizontal stretching or compression, and reflections over the x-axis or the y-axis.

For this problem, the function is:

f(x) = x.

The translation is in the input, f(x - 3), meaning that the function is shifted 3 units right and defined by:

f(x - 3) = x - 3.

Hence three points on the graph are:

Hence the correct description is:

In dataset 60 is the data is spread more tightly around the mean than in other datasets. Accordingly, it would have a smaller standard deviation.

n dataset C, the data is spread more tightly around the mean than in other datasets. Accordingly, it would have a smaller standard deviation

Standard deviation is 60

The term "standard deviation" (or "") refers to a measurement of the data's dispersion from the mean. A low standard deviation implies that the data are grouped around the mean, whereas a large standard deviation shows that the data are more dispersed. In contrast, a high or low standard deviation indicates that the data points are, respectively, above or below the mean. A standard deviation that is close to zero implies that the data points are close to the mean. The curve at the top is more dispersed and has a greater standard deviation than the curve at the bottom, which is more concentrated around the mean and has a lower standard deviation.

The inverse of the function → y= f(x) = 1/7x - 1/7​ is -

f⁻¹(x) = 7x + 1.

We have -

y = f(x) = x/7 - 1/7

We have to find its inverse function.

Inverse of a function can be calculated by following the steps mentioned below -

Step 1 -  Replace 'y' with 'x' and vice - versa.

Step 2 - Rewrite the equation by solving for 'y'.

Step 3 - Replace 'y' with f⁻¹(x).

According to the question, the equation given is as follows

y = f(x) = x/7 - 1/7

Replace 'y' with 'x', we get -

x = y/7 - 1/7

Now, solve for y -

y/7 = x + 1/7

y = 7(x + 1/7)

y = 7x + 1

Replace 'y' with f⁻¹(x) -

f⁻¹(x) = 7x + 1

Hence, the inverse of the function → f(x) = 1/7x - 1/7 is -

f⁻¹(x) = 7x + 1.

Step-by-step explanation:

Answer:

y = 2/3x - 8/3

or 2x = 3y + 8

Step-by-step explanation:

2x = 3y + 4

3y = 2x - 4

y = 2/3x - 4/3

If two lines are parallel, their slopes are equal

if m = 2/3, y = -2, x = 1

y = mx + b

-2 = 2/3(1) + b

-2 = 2/3 + b

b = -2 - 2/3 = -8/3

y = 2/3x - 8/3

or 3y = 2x - 8

or 2x = 3y + 8

The measure of each angle is , ∠E = 117° and ∠F = 63°

In the geometry, angle is defined as the geometry formed by the multiple rays. Or we can also say that the angle is a figure formed by two rays with having same initial point. The rays are also known as the sides of the angle. A angle can have two rays.

Angles which are on the same line are supplementary angles. The sum of supplementary angles are always equals to 180 degree.

Some common terms related to angles :

In the given question:

Let measure of ∠E = x

and, measure of ∠F = y

as ∠E and ∠F are supplementary angles therefore their sum is 180

i.e. m∠E + m∠F = 180

=> x + y =180

also, m∠E is 54 more than m∠F

=> y+54 + y = 180

=> 2y + 54 = 180

=> y = 180-54 / 2 = 63

and , x = y + 54 = 63 + 54 = 117

Hence, ∠E = 117 degree and ∠F = 63 degree

The number of tacos that is needed for 3 students is 8 tacos.

The first step is to determine the number of tacos that is needed for one student. To determine this value, divide the total number of tacos by the total number of students.

Division is the mathematical operation that is used to determine the quotient of two or more numbers. Division entails splitting a number into equal groups using another number. The sign used to denote division is ÷

Tacos that should be prepared for one student = total tacos / number of students

= 40 / 15

In order to determine the number of tacos needed for 3 students, multiply the result gotten in the previous step by 3. Multiplication is the process used in determining the product of two or more numbers. The sign used to denote multiplication is x .

Tacos needed for 3 students = (40 / 15) x 3 = 8
