Step-by-step explanation:
since you understood 1a, I honestly do not understand what's the problem with 1b.
this works exactly the same way. only this time it is x+0 and y changes. that is all.
(x, y) -> (x+0, y-5)

Answer: B. 3x (1 - 3x²)
Step-by-step explanation:
Given

Joanne a total score for a round of darts was -42 she had thrown 6 darts and scored the same each throw How many points did Joanne score on each throw
Answer:
7
Step-by-step explanation:
Answer:
7
Step-by-step explanation:
Ok, so we know 42 is the number of points added up, and we know that she threw 6 darts all scoring the same. Now, all we have to do is figure out what number(for example x) multiplied by 6 equals 42. Or in the form of an equation:
6x = 42
Now, to finish the equation, all we have to do is divide:
6x/6 = 42/6
42/6 = 7
x = 7
Ruth borrowed a book from the library. The library charged a fixed rental for the book and a late fee for every day the book was overdue.

Answer:
The late fee per day for the book
Step-by-step explanation:
2 + .25x
The 2 is the fixed rental for the book
.25x is the late fee per day where .25 is the charge per day and x is the number of days

A student performs several experiments in which he swings a pendulum for a 20 second duration. He uses a string that is 27 cm long, and he test pendulum masses of different sizes, varying from 2 to 12 grams. He records the number of swings each pendulum makes in 20 seconds.
The student then decides to make a second graph showing the string length (in cm) as the independent quantity. What change must the student make to his experiment?
The students must make use of varying string lengths in his experiment in other to make string length the independent quantity.
In the first first scenario,
The number of swings made by each pendulum is the dependent variable, as it is the variable which is measured in the experiment. While ;
The different pendulum masses tested are the Independent variable as it is the variable which is manipulated in other to cause changes to the measured variable.
In other make the string length the independent quantity, the student will need to use strings of different length and not just a string of 27 cm in other to be used as the independent variable. This will enable manipulation of the independent quantity to other to cause changes to the measured variable.

How do you simplify (4m)^5
Hi! I'm happy to help!
To first solve this, we need to know what is going on. In the order of operations, everything inside of the parenthesis happens first. Since 4 and m are being multiplied inside of the parenthesis, that would happen before being moved to the fifth power. Since m is unknown, we make everything inside of the parenthesis to the fifth power, and make sure they are multiplied together as they are inside of the parenthesis. (Everything inside of the parenthesis applies to the raising to the fifth power.)
[tex]4^{5}[/tex]·[tex]m^{5}[/tex]
From here, we can simplify [tex]4^{5}[/tex] to 1024.
1024·[tex]m^{5}[/tex]
We don't need the multiplication sign because it is a variable.
1024[tex]m^{5}[/tex]
Since we cannot simplify m, this is our most simplified form: 1024[tex]m^{5}[/tex]

Answer:
-2 7/8
Step-by-step explanation:
The usual recommendation is to convert the mixed numbers to improper fractions before multiplying.
[tex]-2\dfrac{5}{9}\times1\dfrac{1}{8}=-\dfrac{9\cdot2+5}{9}\times\dfrac{8\cdot1+1}{8}\\\\=-\dfrac{23\cdot9}{9\cdot8}=-\dfrac{23}{8}=\boxed{-2\dfrac{7}{8}}[/tex]
__
Note the factors of 9 cancel in the first expression on the last line, leaving -23/8.
Answer:
[tex]\frac{23}{8}=2\frac{7}{8}[/tex]
Step-by-step explanation:
[tex]-2\frac{5}{9}\times \:1\frac{1}{8}[/tex]
Step 1: Convert into an improper fraction
[tex]2\frac{5}{9}=\frac{2\times 9+5}{9}\\\\=\frac{23}{9}[/tex]
[tex]-\frac{23}{9}\times \:1\frac{1}{8}[/tex]
[tex]1\frac{1}{8}=\frac{1\times 8+1}{8}\\\\=\frac{9}{8}[/tex]
[tex]-\frac{23}{9}\times \frac{9}{8}[/tex]
Step 2: Cross-cancel 9
[tex]=-\frac{23}{8}[/tex]
Step 3: Convert to an improper fraction
[tex]\frac{23}{8}=2\frac{7}{8}\\\\2\frac{7}{8}[/tex]

Which one describes the algebraic expression for the phrase, "eight more than twice a number"?
O (2n)(8)
O 2n + 8
O 2 + 8n
O 2n - 8n
Answer:
2n+8
Step-by-step explanation:
"eight more than twice a number" so twice a number would be 2n because its 2×n (double/twice a number) and eight more would be +8
why is -7 an integer but not a natural number?
Answer:
Natural Numbers are basically "counting numbers". If I ask you to start counting, you'll start at 1, then 2, then 3, and so on. It doesn't include 0 or any negative numbers because you wouldn't start from -10 when asked to count.
brainliest is appreciated :)
Answer:
-7 is negative so it cannot be a natural number, but it is an integer. An integer is a whole number, this means that it does not have any decimal places or fractions. However, a natural number must be a whole non-zero number and positive. This is because natural numbers are numbers found naturally in measurements or in counting. Additionally, all natural numbers are integers but not all integers are natural numbers. For example, -3 would be an integer, 9 would be an integer and a natural number, and 7.6 would be neither.
