For a relation where y is a function of x, y = 4 when x = 6. Which of the following does not represent another possible mapping in the relation?
Choose the correct answer below.
O A. x = 4 maps to y = 6
OB. x = 3 maps to y = 2
O C. X=0 maps to y = 0
OD. X = 6 maps to y = 2
O E. X = 1 maps to y = 6
help asap please.
Answer: D. X = 6 maps to y = 2
Step-by-step explanation:
i guessed and got it right lol
The option that does not represent another possible mapping in the relation is x = 6 maps to y = 2.
This mapping is not possible because we can not have the same inputs for different outputs.
y = 4 when x = 6 (given)
Option D is the answer.
What is a function?A function is a relationship between inputs where each input is related to exactly one output.
Example:
f(x) = 2x + 1
f(1) = 2 + 1 = 3
f(2) = 2 x 2 + 1 = 4 + 1 = 5
The outputs of the functions are 3 and 5
The inputs of the function are 1 and 2.
We have,
Function:
A function can have the same output for different inputs.
A function can not have different outputs for the same inputs
Now,
y = 4 when x = 6.
Other possible mappings are:
A.
x = 4 maps to y = 6
This mapping is possible.
B.
x = 3 maps to y = 2
This mapping is possible.
C.
x = 0 maps to y = 0
This mapping is possible.
D.
x = 6 maps to y = 2
This mapping is not possible because we can not have the same inputs for different outputs.
y = 4 when x = 6 (given)
E.
x = 1 maps to y = 6
This mapping is possible since we can have different inputs for the same outputs.
Thus,
The option that does not represent another possible mapping in the relation is x = 6 maps to y = 2.
This mapping is not possible because we can not have the same inputs for different outputs.
y = 4 when x = 6 (given)
Option D is the answer.

The correct option is C.
What are similar triangles?Those triangles look the same but are different in size.
And in similar triangles,
the corresponding sides are in proportion to each other and the corresponding angles are equal to each other.
Given information:
SM = 27, angle SMA = 31 degrees, MA = 15, DL = 9, LE = 5 and Angle DLE = 31 degrees.
From the given information, we know that angle SMA is congruent to angle DLE because they both have a measure of 31 degrees. However, we do not have any information about the other angles in the two triangles.
To check if the corresponding sides are proportional, we can compare the ratios of the corresponding side lengths:
SM/ DL = 27/9 = 3
MA/LE = 15/5 = 3
Since the ratio of SM to DL is equal to the ratio of MA to LE, we know that the corresponding sides are proportional.
Therefore, we can use the Similarity-SAS (Side-Angle-Side) postulate to conclude that the triangles are similar. The postulate states that if two pairs of corresponding sides are proportional and the included angles are congruent, then the triangles are similar.
The answer is (C) Similar - SAS.

15x + 12(10 - x) = 1417 and 3Step-by-step explanation:
The number of people who have two-course meal is (10 - x)
Correct equation is:
15x + 12(10 - x) = 141Solving for x:
15x + 120 - 12x = 1413x = 141 - 1203x = 21x = 7Answer:
Number who have three-course meal = 7Number who have two-course meal = 3Answers:
1) 15x + 12(10 - x) = 141
2) 7 and 3
15x + 12(10 - x) = 141
15x + 120 - 12x = 141
3x = 141 - 120

Answer:
I think it is X or Y. I might be wrong.
Answer:
∠Y = 85° , side XZ
Step-by-step explanation:
180 = 5x - 1 + 8x + 5 + 4x + 6
180 + 1 - 5 - 6 = 5x + 8x + 4x
170 = 17x
x = 170 / 17
x = 10
∠X = 5(10) - 1 = 49°
∠Y = 8(10) + 5 = 85°
∠Z = 4(10) + 6 = 46°
therefore, the longest side of a triangle is the opposite site of
∠Y = 85° , side XZ

Written as a simplified polynomial in standard form, what is
the result when (2x – 5)2 is subtracted from x-10?
Answer:
[tex]\left(x-10\right)-\left(2x-5\right)^2=-4x^2+21x-35[/tex]
Step-by-step explanation:
As we have to subtract [tex]\left(2x\:-\:5\right)^2[/tex] from [tex]\left(x-10\right)[/tex]
so
[tex]\left(x-10\right)-\left(2x\:-\:5\right)^2[/tex]
solving and simplifying the polynomial in standard form
[tex]\left(x-10\right)-\left(2x-5\right)^2[/tex]
[tex]\mathrm{Remove\:parentheses}:\quad \left(a\right)=a[/tex]
[tex]=x-10-\left(2x-5\right)^2[/tex]
[tex]=x-10-\left(4x^2-20x+25\right)[/tex] ∵ [tex]\left(2x\:-\:5\right)^2=\:4x^2-20x+25[/tex]
[tex]=x-10-4x^2+20x-25[/tex]
[tex]=-4x^2+21x-35[/tex]
We know that standard form means that the terms of the expression are ordered from biggest exponent to lowest exponent.
Thus, a simplified polynomial in standard form is:
[tex]\left(x-10\right)-\left(2x-5\right)^2=-4x^2+21x-35[/tex]

Put the following numbers in order from least to greatest.
0.52
0.6
14/25
57%
Answer:
57% 0.52 14/25 0.6
Step-by-step explanation:
all you have to do is change all of the numbers into decimals
hope this helps :)
First, convert each to the same (#/#, 0.#, or #%). I'll use decimals (usually the easiest). 0.52 and 0.6 remain the same. 14/25 may seem hard at first, but you can change it to 56/100 (14*4/25*4=56/100), then you can use that to convert to 56%. Multiply by 0.01, or divide by 100, remove the %, and you will get 0.56. For 57%, you just need to do repeat the last step again, which will give you 0.57. From least to greatest, the list would be 0.52, 0.56, 0.57, and 0.6, or 0.52, 14/25, 57%, and 0.6.
