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.

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.

Answer:

7

Step-by-step explanation:

this can be written as an equation, which is 4x+2= 30

X = the number of friends

30= the total of stickers

4= the stickers each friend gets

2= the amount lan gets.

Now solve the equation, first subtract 2 on both sides, which is 28

4x=28 now divide both sides by 4, which will give you 7

x= 7, that means that answer is 7

Answer:

A) (2, 6)

General Formulas and Concepts:

Algebra I

Step-by-step explanation:

The solution set of the systems of equations would be where the 2 lines intersect. According to the graph, the equations intersect at (2, 6). Therefore, our answer is A.

This will generate a line quickly dropping from left to right, with an x-intercept of 0.4 and a y-intercept of 2.

Answer:

Step-by-step explanation:

C

The theorem that applies is Similar SAS.

The correct option is C.

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.

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]

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
