Answer:
Let y = f(x) be a function with an independent variable x and a dependent variable y.
If a function f provides a way to successfully produce a single value y using for that purpose a value for x then that
chosen x-value is said to belong to the domain of f. If there is a requirement that a y-value produced by a function
must be a real number, the following conditions are commonly checked:
1. Denominators cannot equal 0.
2. Radicands (expressions under a radical symbol) of even roots (square roots, etc)
cannot have a negative value.
3. Logarithms can only be taken of positive values.
4. In word problems physical or other real-life restrictions might be imposed, e.g. time is
nonnegative, number of items is a nonnegative integer, etc.
Answer:
the domain is a set of all possible numbers inputs for that function, THe range is all the possible output numbers

4 lbs 7 oz; oz
conversions ratios thing
Answer:
4 lb 7 oz = 71 oz
Step-by-step explanation:
Do you need to convert 4 lb 7 oz into oz?
If so, do the following.
Obviously, 7 oz is already in oz, so all you need to do is convert 4 lb into oz and then add 7 oz.
1 lb = 16 oz
For every lb, there are 16 oz. To convert lb to oz, multiply the number of lb by 16.
4 lb = 4 * 16 oz = 64 oz
4 lb 7 oz = 4 lb + 7 oz = 64 oz + 7 oz = 71 oz
I need help plz I would appreciate it

BC has a midpoint at M(6, 6). Point C is at (2, 10). Find the coordinates of point B.
Answer:
The coordinates of B are (10,2)
Step-by-step explanation:
Hi there!
We know that BC has a midpoint M, with the coordinates (6,6), and the endpoint C, with coordinates (2, 10)
We want to find the coordinates of point B
The midpoint formula is [tex](\frac{x_1 + x_2}{2}, \frac{y_1+ y_2}{2})[/tex], where [tex](x_1, y_1)[/tex] and [tex](x_2 , y_2)[/tex] are points. In this case, the point C has the values of [tex](x_1, y_1)[/tex], and B has the values of [tex](x_2 , y_2)[/tex]
We know that coordinates of M equal [tex](\frac{x_1 + x_2}{2}, \frac{y_1+ y_2}{2})[/tex]
In other words,
[tex]\frac{x_1 + x_2}{2} = 6\\ \frac{y_1+ y_2}{2}=6[/tex]
Let's plug 2 for [tex]x_1[/tex] and 10 for [tex]y_1[/tex]
So:
[tex]\frac{2 + x_2}{2} = 6\\ \frac{10+ y_2}{2}=6[/tex]
Multiply both sides by 2
[tex]{2 + x_2} = 12\\{10+ y_2} =12[/tex]
Subtract 2 from both sides in the first equation to find the value of [tex]x_2[/tex]:
[tex]x_2=10[/tex]
Now, for the second equation, subtract 10 from both sides to find the value of [tex]y_2[/tex]
[tex]y_2=2[/tex]
Now substitute these values for [tex](x_2, y_2)[/tex]
[tex](x_2, y_2)=(10,2)[/tex]
So the coordinates of point B are (10, 2)
Hope this helps!

i didn't pay attention to the class
Answer:
x=2
Step-by-step explanation:
Let's solve your equation step-by-step.
Step 1: Simplify both sides of the equation.
12=2x+4x
12=(2x+4x)(Combine Like Terms)
12=6x
12=6x
Step 2: Flip the equation.
6x=12
Step 3: Divide both sides by 6. 6x/6=12/6
x=2
Hope you found this helpful and have good day (.
Answer:
2
Step-by-step explanation:
plus the like-terms (x plus x): 2+4
so 12=6x. get 6 out of the x-term. X is the unknown number being multiplied by 6. To get it to the other side, divide the numbers. So: 12/6=x and 12/6 is 2. so x=2.

The sum of 24 and x is - 20.
Answer:
x+24 = -20
this is the equation form
Answer:
24 + x = -20
Step-by-step explanation:
"The sum" is simple addition, so stating that the "sum of 24 and x" is the same as :
24 + x
Seeing as they equal -20:
24 + x = -20

How many different 9-letter "words" can you
make by arranging the letters in DEVIATION?
The arrangements don't have to be actual words
that are included in any dictionary.
There are 5040 different 9-letter “words” that can be made by arranging the letters in DEVIATION.
The given word is DEVIATION and we are required to find out the number of different 9-letter “words” that can be formed by arranging its letters.
To solve the problem, we will use the formula for finding permutations of n objects taken r at a time when all the objects are distinct.
The formula is given by: nPr = n! / (n-r)! where n is the total number of objects and r is the number of objects to be selected.
Here, we have 9 objects (letters) and we need to arrange all of them, so r = 9.
Now, we need to find out the value of n.
The given word DEVIATION has 9 letters, but two of them (E and I) are repeated twice.
Therefore, n = 9 - 2 = 7.
We will substitute these values in the formula to get the required answer:
nPr = n! / (n-r)! = 7! / (7-9)! = 7! / (-2)! = 7! / 1 = 5040
Therefore, there are 5040 different 9-letter “words” that can be made by arranging the letters in DEVIATION.
