Suppose If we say the average income of a population is five thousand.
This implies that some portion of the population earns more than five thousand and some portion of the population earns below five thousand.

1) If g(x) is a linear function, g(-2) = 6 and g(2) = 18, what is the rate of change? Is this function increasing or decreasing? Show your work!
Answers:
Rate of change = 3
The function is increasing
===================================================
Explanation:
The notation g(-2) = 6 means the input x = -2 leads to the output y = 6. Therefore, the point (-2,6) is on f(x). The other point given is (2,18).
For linear functions, the terms "rate of change" and "slope" are the same thing.
Let's use the slope formula on the two points (-2,6) and (2,18)
[tex](x_1,y_1) = (-2,6) \text{ and } (x_2,y_2) = (2,18)\\\\m = \frac{y_{2} - y_{1}}{x_{2} - x_{1}}\\\\m = \frac{18 - 6}{2 - (-2)}\\\\m = \frac{18 - 6}{2 + 2}\\\\m = \frac{12}{4}\\\\m = 3\\\\[/tex]
The slope is 3, which can be written as 3/1
A slope of 3/1 means we go up 3 and to the right 1.
slope = rise/run = 3/1
rise = 3 = go up 3
run = 1 = go to the right 1
Since the slope is positive, this means the line is going uphill as we move to the right. In other words, the function is increasing.

What is basic algebra ?Algebra is a branch of mathematics that helps translate real-world situations or problems into mathematical truths. Mathematical operations like addition, subtraction, multiplication, and division are needed in addition to variables like x, y, and z to construct a meaningful mathematical expression. All branches of mathematics, such as calculus, trigonometry, and coordinate geometry, employ algebra. A fundamental algebraic equation is 2x + 4 = 8. Algebraic expressions serve as the mathematical statement when operations such as addition, subtraction, multiplication, division, etc. are done on variables and constants. Let's imagine that while playing with matchsticks, James and Natalie came up with the idea to arrange the sticks into designs that represented numbers.
Given that : 1 euro is 120 yen and 1 pound is 1.2 euro
1 euro = 120 yen
1 pound = 1.2 euro
1 pound = 1.2 × 120 yen
1 pound = 144 yen
50 pound = 144 ×50
= 7200 yen
50 pound in yen is 7200 yen

Help me graph the relationship please! I've been stuck on this problem for a week now... :<
Rate of change (m) = 10
Starting amount (b) = 14
It takes 9 days to have 104 boondins.
The equation in slope-intercept form is: y = 10x + 14
Its graph is shown below.
How to Write the Equation of a Line?Where m represents the rate of change and b represents the y-intercept or starting value, the equation of a line can be written in slope-intercept form as:
y = mx + b.
From the information given, the following are given about the line:
x = number of days
y = total number of boondins
If he had 74 boondins in 6 days and he bought 10 more every day, then:
x = 6
y = 74
Starting value (b) = ?
Rate of change (m) = 10
Substitute the values into y = mx + b to find the value of b:
74 = 10(6) + b
74 = 60 + b
74 - 60 = 60 + b - 60
14 = b
b = 14
Therefore:
Rate of change (m) = 10
Starting amount (b) = 14
To write the equation in slope-intercept form, substitute b = 14 and m = 10 into y = mx + b:
y = 10x + 14
To find how many days it takes to have 104 boondins, substitute y = 104 into the equation, y = 10x + 14:
104 = 10x + 14
Solve for x
104 - 14 = 10x
90 = 10x
90/10 = 10x/10
9 = x
x = 9
It takes 9 days.
For 10 days, it would take:
y = 10(10) + 14
y = 114 boondins
The table is:
(x, y)
(0, 14)
(10, 114)
The graph for y = 10x + 14 is given in the attachment.

A bottled water company quality control officer wants to find out how well the label machines are working. He is studying every machine and every bottle to make sure it is usable to a customer. Which represents a population?
the first fifty bottles labeled on Monday morning
one hundred bottles
all the bottles with incorrectly placed labels
all the bottles produced in one day
All the bottles produced in one day represents the population in statistics .
In statistics, a population is a collection of similar things or events that are important to a specific experiment or topic.
A statistical population can be made up of actual objects (such all the stars in the Milky Way galaxy) or hypothetical groups of things that are assumed to be an infinite number of objects based on experience-based generalizations (e.g. the set of all possible hands in a game of poker). A common objective of statistical analysis is to gather information about a chosen community.In statistical inference, a subset of the population (a statistical sample) is chosen to represent the population in a statistical study.The statistical sample must also fairly and accurately represent the population.Since the population represents all the data for a particular time period , in this case we can conclude that the population for the factory will be all the bottles produced in 1 day.

Jerald is having drain issues at his home and decides to call a plumber. The plumber charges $70 to come to his house and $50 for every hour they work. If the plumber charges Jerald a total of $285, how many hours did the plumber work?
Write and solve an equation to determine the number of hours worked by the plumber.
50x − 70 = 285; x = 7.1 hours
50x + 70 = 285; x = 4.3 hours
70x − 50 = 285; x = 4.8 hours
70x + 50 = 285; x = 3.4 hours
Answer: B
Step-by-step explanation:
A $70 is fixed, we have to add $50 each hour. So, it will be 70 + 50x. If he charged $285 overall, this means that 70 + 50x = 285
50x = 285 - 70
50x = 215
x = 215/50 = 4.3

We can conclude that the angle ∠RST is 110°.
What are angles?An angle is a figure in plane geometry that is created by two rays or lines that have a common endpoint. The Latin word "angulus," which means "corner," is the source of the English word "angle." The common endpoint of two rays is known as the vertex, and the two rays are referred to as the sides of an angle.So, as we can see line R and line T are parallel to each other.
Join, R and T with a line that makes a right angle with both lines.(Refer to the image attached below)
Now, we know that ∠R = 90° and ∠SRT = 90 - 60 = 30°.Similarly, ∠T = 90° and ∠STR = 90 - 50 = 40°.In triangle SRT, we know the two angles which are ∠R = 30° and ∠T = 40°.
We know that sum of all angles in a triangle is 180°.So, ∠S in triangle SRT will be:
40 + 30 + ∠S = 18070 + ∠S = 180∠S = 180 - 70∠S = 110Therefore, we can conclude that the angle ∠RST is 110°.

The number of cans each guest must bring to reach the goal must be greater than or equal to 5 by inequality.
What is inequality in math?
In mathematics, inequalities specify the connection between two non-equal numbers. Equal does not imply inequality. Typically, we use the "not equal sign ()" to indicate that two values are not equal. But several inequalities are utilized to compare the numbers, whether it is less than or higher than.Let
x -----> the number of cans each guest must bring to meet the goal
we know that
The number of guests multiplied by the the number of cans each guest must bring to meet the goal plus the currently cans must be greater than or equal to 1,000 cans
so
The inequality that represent this problem is
565 + 87x ≥ 1000
Solve for x
565 + 87x ≥ 1000
Subtract 565 both sides
87x ≥ 1000 - 565
87 ≥ 435
Divide by 87 both sides
x ≥ 435/87
x≥ 5
therefore, The number of cans each guest must bring to reach the goal must be greater than or equal to 5.
