Step-by-step explanation:
8 - 6r + 3 = 5
Combine like terms
11 - 6r = 5
Subtract 5 from both sides

Add 6r to both sides
6 = 6r

M*thway is a pathway to many abilities some considered to be... unnatural
Statement (C) the y-intercept is y=-1 describes the graph of the function.
What is a function?It is defined as a special type of relationship, and they have a predefined domain and range according to the function every value in the domain is related to exactly one value in the range.
We have a function:
[tex]\rm f(x) = \dfrac{x^2-1}{x^2-2x+1}[/tex]
The above function is a rational function.
The denominator cannot be zero
x² - 2x + 1 ≠ 0
(x - 1)²≠ 1
x ≠ 1
To find y-intercept plug x = 0
f(0) = -1
Thus, statement (C) the y-intercept is y=-1 describes the graph of the function.

which algebraic equation represents the words: forty percent of mrs. garcia's score is 400 points. what is mrs. garcia's score?
Answers
The algebraic equation "0.40x = 400" represents the words: forty percent of Mrs. Garcia's score is 400 points. Mrs. Garcia's score is 1000.
Algebraic equation is an equation made up of variables and coefficients that can be used to solve mathematical problems or questions.
To formulate an algebraic equation, we designate a variable for unknown values.
Mrs. Garcia's score is unknown, and so
let x = Mrs. Garcia's score
Based on the information given on the problem, forty percent of Mrs. Garcia's score is 400 points. Forty percent can be written as 0.40.
40% of x is 400
0.40x = 400
Hence, the algebraic equation for that is 0.40x = 400.
Evaluating the value of x,
0.40x = 400
x = 400 / 0.40
x = 1000
Therefore, Mrs. Garcia's score is 1000.

In an observational study, the researcher simply observes and records data as it naturally occurs, without interfering or influencing the study participants.
This type of study is often used in social science research, as well as in medical research and epidemiology, to study the relationships between variables and to identify patterns or trends in the data.
Observational studies can be either cross-sectional, where data is collected at a single point in time, or longitudinal, where data is collected over an extended period of time.

I need help plsssss ...... name the transversal that connects them and classify the angle pair
Answers
Answers:
The transversal line is line s
The angles 6 and 16 are same side exterior angles
=================================================
Explanation:
Erase everything but lines p, q, and s. Also, we'll keep angles 6 and 16 as well. Check out the diagram below.
As you can see from the diagram, lines p and q act like the parallel lines. Imagine we can shift line p to make it horizontal so it's parallel to line q. This might help show that angles 6 and 16 are same side exterior angles.
Note: Because line p is not parallel to line q, this means angles 6 and 16 are not supplementary (they don't add to 180).
Tim has a bag of 36 orange-flavoured sweets and Peter has a bag of 44 grape-flavoured sweets. They have to divide up the sweets into small trays with equal number of sweets; each tray containing either orange-flavoured or grape-flavoured sweets only. If there is no remainder, find the largest possible number of sweets in each tray.
Answers
Answer:
the largest possible number for each would be dividing it by two so 36 divided by two is 18 and 44 divided by two is 22
so for the orange the largest number would be 18
and for the grape the largest number would be 22

Cora ran 3 miles last week and will run 7 miles per week from now on. Hana ran 9 miles last week and will run 4 miles per week from now on.
In the answer box,
Write a system of equations to describe this scenario. Identify what the variables mean in the context of the problem.
Answers
Answer:
If Cora runs 1/2 mile per week and x is the number of weeks, then she will run 5+1/2x. Then determine how many weeks are in two and a half months (depends on which month it is as there are less weeks in February than in January!) but we could estimate 6.
For Hana, you will have 3+ 3/4 x
Step-by-step explanation:
First equation is y=5+1/2 x and then plug 6 in for x to solve for y. the second equation is y=3+3/4x and plug in 6.
The system of equations to describe this scenario are
y = 3 + 7xy = 9 + 4xThe variable x means the number of weeks they ran and the y variable means the total distance they covered in miles .
The situation can be modelled like a linear equation.
Therefore,
y = mx + b
where
m = slope
b = y-intercept
Cora race will be as follows:
y = 3 + 7xHana race will be as follows:
y = 9 + 4xThe variable x which is the independent variable is the number of weeks each of them ran in the equation.
The variable y which is the dependent variable is the total distance covered in miles.

population screening of risky alcohol and drug use via internet and interactive voice response (ivr): a feasibility and psychometric study in a random sample
Answers
There were substantial differences in alcohol and drug usage by the manner of administration, however, problem drinking and drug use were present in 21.1% and 2.8% of the group, respectively.
What do you mean by population screening of risky alcohol and drug?The topic of whether data from population surveys could be gathered more quickly and affordably than using paper questionnaires is brought up by the widespread accessibility of computer-based technologies like the Internet and Interactive Voice Response (IVR) systems. The issue extends to whether it is possible to assess the prevalence of such behaviors in the general population when dealing with potentially stigmatized behaviors like problematic alcohol and drug use without endangering the accuracy of the findings. This study evaluates the reliability, response rate, and problematic alcohol and drug use of the Internet and IVR versions of the AUDIT and DUDIT. Randomly chosen from the Swedish general population, 5000 people were contacted by mail and asked to respond to the AUDIT and DUDIT questionnaires online or over the phone.

Answers
The minutes it will take for the tank to be 3/5 full is 720 minutes.
When the tank be 3/5 full?A fraction is a non-integer that is made up of a numerator and a denominator. The numerator is the number above and the denominator is the number below. An example of a fraction is 3/5.
The first step is to determine how many gallons the tank would have when it is 3/5 full. To determine this value, multiply the volume of the tank by 3/5.
Gallons when the tank is 3/5 full = 3/5 x 48,000 = 28,800
Now, divide the speed of the water by the gallons in the tank when it is 3/5 full.
28,800 / 40 = 720 minutes
