1. The average change in population is not the same now as it was 50 years ago. The population growth rate can vary greatly from year to year and decade to decade, and is influenced by a variety of factors such as birth and death rates, immigration, and emigration. Therefore, it is important to analyze the specific data for each time period to determine the average change in population.

2. When interpreting data on population growth or decline, it is important to consider the factors that influence population change and to analyze the data in the context of the specific time period being studied. It is also important to consider the accuracy and reliability of the data source, as well as any potential biases or limitations in the data.

3. When comparing population growth or decline over different intervals of time, it is important to consider a range of factors that can influence population change, such as birth and death rates, migration patterns, economic and environmental conditions, and government policies. For example, population growth rates in a country may be influenced by changes in healthcare access or advancements in technology that reduce infant mortality rates or increase life expectancy. In addition, migration patterns can greatly impact population growth rates, as some regions may experience large influxes of immigrants or emigrants at different periods in time. When comparing population data over different intervals of time, it is important to take into account these and other factors that may contribute to population growth or decline.

Answer:

-x-12

Step-by-step explanation:

Given:

\(\displaystyle \large{|x-(-12)| \quad (x < -12)}\)

Simplify:

We know that negative times negative equals positive, therefore:

\(\displaystyle \large{|x+12| \quad (x < -12)}\)

Modulus Property:

\(\displaystyle \large{|x+a| = \begin{cases} x+a \quad (x \geq -a) \\ -x-a \quad (x < -a) \end{cases}}\)

Therefore, since given interval is x < -12:

\(\displaystyle \large{|x+12| \quad (x < -12) = -x-12}\)

Hence, simplified expression is -x - 12

Answer:

-2/3 = x

Step-by-step explanation:

first subtract 7 on both sides like this:

3x 7-7 = 5-7

then you will get this:

3x=-2

finally divide both sides by 3 to isolate the x term like so:

3x/3 = -2/3

your final answer is x = -2/3

The decimal is 6.4 which is equivalent to 6×1 + 4×1/10.

Arithmetic operations can also be specified by the subtract, divide, and multiply built-in functions.

The operator that performs the arithmetic operations are called arithmetic operators.

Operators which let do a basic mathematical calculation

+ Addition operation: Adds values on either side of the operator.

For example 4 + 2 = 6

- Subtraction operation: Subtracts the right-hand operand from the left-hand operand.

for example 4 -2 = 2

* Multiplication operation: Multiplies values on either side of the operator

For example 4*2 = 8

/ Division operation: Divides left-hand operand by right-hand operand

For example 4/2 = 2

Given that the expression as:

⇒  6×1 + 4×1/10

Apply the arithmetic operations in the terms,

⇒ 6 + 4×0.1

⇒ 6 + 0.4

⇒ 6.4

Thus, the decimal is 6.4 which is equivalent to 6×1 + 4×1/10.

I would write a equation.

Answer: a

Step-by-step explanation:

The area of the given trapezoid, using the given dimensions, is calculated to be 150 cm2, which is not among the provided choices, hence none of them are correct.

The figure described seems to be a trapezoid, which is a five-sided figure with two parallel sides. The formula to calculate the area of a trapezoid is (base1+base2)/2 * height. In this case, we have one base being 18 cm (the shorter parallel side), but we don't have the length of the other base. However, given the height and the two components of the unknown base, we can infer the remaining base is 7 cm (4 cm from vertex to height and 3 cm from a point to a vertical line created by two vertices). Thus, given the indices, the calculation would be: (18cm + 7cm)/2 * 12cm. Therefore, the total area of the figure is 150 cm2, which is not an option in the given choices. Hence, none of the options A, B, C, D are correct based on the provided data.

Answer: 8 hours

Step-by-step explanation:

Let x be the time before they meet ( in hours)

Speed of Sam = 12 mph

Sped of Fred = 9 mph

Distance = Speed × time

Distance covered by Sam in x hours = 12x

Distance covered by Fred in x hours = 9x

                                               (Distance)     (rate1) (time1)          (rate2) (time2)  

Total distance between them: 168             =     12      x        +      9    x

\(\Rightarrow\ 168= 21x\\\\\Rightarrow\ x=\dfrac{168}{21}=8\)

Hence,  the number of hours before they meet if Sam runs 12 mph and Fred runs 9 mph. = 8

Answer:

300 feet

Step-by-step explanation:

If we were using feet the expression would be 198x, where x is feet per second

Since they are asking in meters we need to convert feet to meters

When you do that you get 60

Now the expression is 60x

When you plug 5 into the equation it is 300

The function for the points are  y = -15x - 5

From the information given, we have that;

The points are;

(1/3,0) (-2 3/4,0) and (0,-5)

Using the point-slope form of a linear equation, we have;

y - y₁ = m(x - x₁)

Such that;

Using (1/3, 0) and (0, -5), we have that the slope is;

m = (0 - (-5))/0 -1/3)

expand the bracket

= 5 / (-1/3)

= -15

Now, take any of the given points and substitute the values

Using (1/3, 0), we get;

y - 0 = -15(x - 1/3).

y = -15x - 5.

The function for the points solved by  (1/3,0) (-2 3/4,0) and (0,-5) solved by point slope form is \(a=-15b-5\)

We have given the points:

(1/3,0) (-2 3/4,0) and (0,-5)

Using the formula of linear equation

\(a-\)\(a_{1}\)\(=x[b-b_{1}]\)                                                          

Where we will consider (1/3,0) = \(a-a_{1}\) and (0,-5) = \(b-b_{1}\)

that is 1/3 = \(a\), 0 = \(a_{1}\) and

0 = \(b\), -5 = \(b_{1}\)

\(x\) refers to the slope of line (take any variable)

Now for finding the value of \(x\),

\(x=a-a_{1}/b-b_{1}\)

inserting the values,

\(x=[0-[-5]]/[0-1/3]\\x= -15\)

Substitute the value of \(x\) in the equation

\(a-0=-15[b-1/3]\)

By simplifying the equation, we get

\(a=-15b-5\)

let the number=x

x-4=-3x

x+3x=4

4x=4

x=4/4=1

The number that is four greater than three times its additive inverse

is - 3n + 4.

A number's additive inverse is a number that is added to it until the result is zero.

A number multiplied by another such that the result is 1 is the multiplicative inverse of that number.

Let the unknown number be 'n' so its additive inverse is '-n'.

So,  the number that is four greater than three times its additive inverse is,

Three times of additive inverse is -3n.

========================================================

Explanation:

We have these three rules for scale factors

With those rules in mind, we have enlargements for these transformations.

All of which represent some scale factor larger than 1. We don't have enough information to pinpoint what that scale factor would be.

In other words, if you go from small to big, then you apply some scale factor larger than 1 to enlarge the image.

----------------

We also have these reductions

This is where we go from big to small. The image shrinks and we use some scale factor between 0 and 1.

----------------

And finally we have these transformations in which the size of the image does not change. Therefore the scale factor is 1.

The order doesn't matter for this subset, but the order will matter for the other batches of transformations.
