Which of these is a set of inputs and outputs for the function f(x) = 2x + 4 ?
Answer:
(1, 6), (2, 8), (3, 10)
2(1) + 4 = 6, 2(2) + 4 = 8 and 2(3) + 4 = 10.
Step-by-step explanation:
The set of inputs for the equation f ( x ) = 2x + 4 is
( 1 , 6 ) , ( 2 , 8 ) , ( 3 , 10 )
What is an Equation?
Equations are mathematical statements with two algebraic expressions flanking the equals (=) sign on either side.
It demonstrates the equality of the relationship between the expressions printed on the left and right sides.
Coefficients, variables, operators, constants, terms, expressions, and the equal to sign are some of the components of an equation. The "=" sign and terms on both sides must always be present when writing an equation.
Given data ,
Let the equation be f ( x ) = 2x + 4
f ( x ) = y
Now ,
Let the first point be A ( 1 , 6 )
Let the second point be B ( 2 , 8 )
Let the third point be C ( 3 , 10 )
a)
A ( 1 , 6 )
Substitute the value of x and y in the equation , we get
y = 2x + 4
6 = 2 ( 1 ) + 4
6 = 2 + 4
6 = 6
Hence , the input A ( 1 , 6 ) satisfies
b)
B ( 2 , 8 )
Substitute the value of x and y in the equation , we get
y = 2x + 4
8 = 2 ( 2 ) + 4
8 = 4 + 4
8 = 8
Hence , the input B ( 2 , 8 ) satisfies
c)
C ( 3 , 10 )
Substitute the value of x and y in the equation , we get
y = 2x + 4
10 = 2 ( 3 ) + 4
10 = 6 + 4
10 = 10
Hence , the input C ( 3 , 10 ) satisfies
Hence , The set of inputs for the equation f ( x ) = 2x + 4 is
( 1 , 6 ) , ( 2 , 8 ) , ( 3 , 10 )

What is an equation of the line that passes through the points (-7,-7) and (-7,4) ?
(-7,-7) and (-7,4)
First we need to find the slope between these two points
(y2-y1) / (x2-x1) = -11 / 0 =
Therefore there is no slope.
So, the equation that is possible is:

What is The geometric series 24_8+8/3_8/9+8/27_8/81 usn siga notaton
Answer:
17
Step-by-step explanation:
Use BODMAS Method
B - Brackets
O - Power
D - Division
M - Multiplication
A - Addition
S - Subtraction
24 - 8 + 8/3 - 8/9 + 8/27 - 8/81
First division
8/3 = 2.66666666667
8/9 = 0.88888888888
8/27 = 0.29629629629
8/81 = 0.09876543209
Then Subtract
24 - 8 = 15
2.66666666667 - 0.88888888888 = 1.77777777779
0.29629629629 - 0.09876543209 = 0.1975308642
Then lastly add
15 + 1.77777777779 + 0.1975308642 = 16.975308642
In these type of questions, the answer have decimals, so we have to round it to near whole number.

What is the distance, d, between the points (2,5/2) and (8/3,1)?
Enter your answer in the box. Enter your answer in simplest radical form.
Answer:
um 3 5/4
Step-by-step explanation:
The distance, d, between the points (2,5/2) and (8/3,1) will be; 1.6415 units.
What is the distance between two points ( p,q) and (x,y)?The shortest distance (length of the straight line segment's length connecting both given points) between points ( p,q) and (x,y) is:
D = √[(x-p)² + (y-q)²]
So, we will use the distance formula:
Let (2, 5/2) be (x₁, y₁) and let (8/3, 1) be (x₂, y₂).
Now Substitute:
D = √[(1 - (5/2))² + (8/3 - 2)²]
Evaluate the expressions within the parentheses;
D = √[(1 - (5/2))² + (8/3 - 2)²]
D = √[(-3/2)² + (2/3)²]
Evaluate:
D = √[9/4 + 4/9]
Square:
D = √97/6
Hence, the distance, d, between the points (2,5/2) and (8/3,1) will be; 1.6415 units.

A group of students were discussing whether the relationship on the graph
is a function.
Answer:
A function is a relationship that maps the elements of a set, the domain, into elements of another set, the range.
The restriction that we have for functions is: The elements on the domain can be mapped into only one element in the range.
Then if:
f(x1) = y1
and
f(x1) = y2
where y1 is different than y2
f(x) is not a function.
Now, in the graph you can see a region where both lines overlap, then for some values of x we have two possible values of y, this means that the graph does not represent a function.
Then:
Ed: He is incorrect because we can have different values in the domain mapped into the same value in the range (like in the case of a line y = b, where we have all the elements in the domain mapped into the same element in the range, b)
Debra: There is something called piecewise functions, that are functions of this type, formed by different pieces.
Alejandro: He is correct.
Antoine: Not because you can write an equation means that the relation is a function. You can write an equation for a circle, but it will not be a function.

From left to right for the tables :
[tex]1) \: \: \: \: y = 4x + 2[/tex]
And
[tex]2) \: \: \: \: y = 3x - 12[/tex]
♥️♥️♥️♥️♥️♥️♥️♥️♥️♥️♥️♥️♥️♥️
To find the solution we need to take equal above equations .
[tex]4x + 2 = 3x - 12[/tex]
Subtract sides 3x
[tex] - 3x + 4x + 2 = - 3x + 3x - 12 \\ [/tex]
[tex]x + 2 = - 12[/tex]
Subtract sides 2
[tex]x + 2 - 2 = - 12 - 2[/tex]
[tex]x = - 14[/tex]
Thus the x-coordinate of the solution must be -14 which is just in the last option.
Thus the correct answer is the last one.

Sally wants to start a small business. She plans to sell snack packs by re-packing cookies and coffee sachets. Cookies come in packs of 10, while 3-in-1 coffee sachets come in packs of 12.
What is the smallest number of packs for each item should Sally buy if she wants to have packs with 1 cookie and 1 coffee sachet?
Answer: She needs 6 packs of cookies and 5 packs of coffee sachets.
Step-by-step explanation:
Cookies: come in packs of 10
Coffee sachets: come in packs of 12.
Sally wants to sell them in groups of 1 cookie and 1 coffee sachet, then we need to find a common multiple of 10 and 12. (the smallest one in this case).
To find the smallest common multiple, first let's find the largest common factor between 10 and 12.
If we write the numbers as a product of prime numbers, we have:
10 = 2*5
12 = 2*3*3
The only common factor is 2.
Then the smallest common multiple between 10 and 12 is equal to the product of 10 and 12 divided by the largest common factor between them, in this case is 2.
M = 10*12/6 = 60
Now to find the number of packages of each thing that she must buy, we need to divide 60 by the number of elements in each pack.
Cookies: 10 per pack
60/10 = 6
She needs 6 packs of cookies
Coffe: 12 per pack
60/12= 5
She needs 5 packs of coffee sachets.
