Answer: It is not a function.
Step-by-step explanation:
A function is something that "eats" an input and transforms it into an output.
We write them as y = f(x)
Where x is the input, and y is the output.
Now, a function has an important rule, for each input x, the function can only "transform it" (or map it) into only one possible output.
This means that, for example, if we have, for x = x1.
And a single
f(x1) = y1
f(x1) = y2
where y1 and y2 are different values.
Then this is not a function, because it is mapping the value x1 into two different outputs.
In this case, we would have:
f(Z) = A.
So Z is the input, but we know that a ZIP code works for an entire city, and in a given city we have lots of different street addresses, then for a single value of the input, Z, we have a lot of possible values of the output.
This means taht the set (Z, A) can not represent a function.

Answer:
x = 4
Step-by-step explanation:
Step 1: Write out equation
3x + 6 = 18
Step 2: Subtract 6 on both sides
3x = 12
Step 3: Divide both sides by 3
x = 4
Answer:
4
Step-by-step explanation:
3x +6 =18
3x =18 - 6

Question 4
Point P is presently located at the origin. Move P, and observe how the rotated images change. Be sure that neither the images nor the preimage
overlap. Record the distances of the vertices of the preimage AABC from P. Do the same for the other images. Round all of your answers to the
hundredths place.
Thanks so much
Answer:here ya go boys
Step-by-step explanation:
Answer:
No matter where the center of rotation is located on the coordinate plane, each point in the preimage is the same distance from the point of rotation as its corresponding point in the rotated images. This distance is not affected by changing the location of P. Although this investigation covered vertices only, it's clear that any point on a shape or figure will be affected similarly.

Somebody plz just answer number 11!!!
Thanks (Will mark as if correct brainliest)
:D
Answer:
27.38
Step-by-step explanation:
This is the answer because:
1) Standard form means to write the full number
2) First we have to multiply because we have to use order of operations
3) So do 2 x 10 which is 20
4) Then, do 7 x 1 which is 7
5) Next, do 3 x 0.1 which is 0.3
6) Finally, do 8 x 0.01
The new equation is:
20 + 7 + 0.3 + 0.08
This expression equals to 27.38
Therefore, the answer is 27.38

In 1979, zoologists estimated the number of fish in a local pond to be about
540. In 1989, 10 years later, the zoologists estimated that the number of
fish had increased to 990. Assuming that the fish population increased
linearly, how many fish lived in the pond in 1986? *
ann
Answer:
693 fish
Step-by-step explanation:
In 10 years, we can tell that the amount of fish increased by 1.833...(990 divided by 540) times. If we divide 1.833... by 10, we can find how much the pond increases by yearly. we get 0.1833... If we multiply that by 7 (because the gap between 1986 and 1979 is 7 years), we get 1.2833... So, if we multiply 540 by 1.28333..., we get 693 fish.
The function whose graph is shown below has the following characteristics.
• Two absolute minima
• One relative maximum
O A. True
O B. False
The given graph has two absolute minima as no points are below them and one relative maximum as there is a change in direction from increasing to decreasing at that point. Hence, Option A. True is the right choice.
What are absolute maxima and absolute minima?The absolute maxima and absolute minima are the points on the graph where the graph shows the highest and the lowest values respectively.
What are relative maxima and relative minima?The relative maximum is the point on the graph where the graph changes its direction from an increasing function to a decreasing function.
The relative minimum is the point on the graph where the graph changes its direction from a decreasing function to an increasing function.
How to solve the question?In the question, we are asked whether the given statement:
The function whose graph is shown below has the following characteristics.
• Two absolute minima
• One relative maximum,
is true or not.
In the given graph, we can observe that it was first a decreasing function, until a certain point, then it starts increasing until a certain point, then again decreased until a certain point, and after that went on increasing.
Hence it shows 3 points of inflections.
The first point is an absolute minimum point as the graph never goes below it.
The second point is a relative maximum as there is only a change in direction at that point, and there are points higher than that point.
The third point is an absolute minimum point as the graph never goes below it.
Therefore, we can say that the graph has:
Two absolute minimaOne relative maximumHence, the given statement is A. True.

In both the triangles , length of :
Perpendicular = 4 cm
Base = 6 cm
So , Area of both triangles = [tex]2(\frac{1}{2} * Base * Perpendicular) = 2(\frac{1}{2}* 6 * 4) = 24 cm^2[/tex]
In the 3 rectangles ,

(b) is the product of 2x - 5 and 3x2 + 5x - 7equal to the product of 5x - 2 and 3x2 + 5x - 7? Explain your
answer.
Answer:
a) 6x³ − 5x² − 39x + 35
b) no
Step-by-step explanation:
(2x − 5) (3x² + 5x − 7)
Distribute:
3x² (2x − 5) + 5x (2x − 5) − 7 (2x − 5)
Distribute again:
6x³ − 15x² + 10x² − 25x − 14x + 35
Combine like terms:
6x³ − 5x² − 39x + 35
5x − 2 is the opposite of 2x − 5, so you would get the negative of the answer from part (a).

G is between E and H, and F is the midpoint of EG. If FG=2 and FH=8, find EH.
Answer:
EH = 10
Step-by-step explanation:
Because F is a midpoint, that means that FG and EF are congruent to each other. So, since FG = 2, that means that EF also equals 2. Because FH also includes FG, you can take the 2 from the FG, and then take that 2 away from 8. Now you know that GH = 6. All that is left is to add all 3 of the units together (2+2+6=10).

2m - n =8 Solve for n
Answer:
[tex] \boxed{\sf n = 2m - 8} [/tex]
Step-by-step explanation:
Solve for n:
⇒2m - n = 8
Subtract 2 m from both sides:
⇒2m - 2m - n = 8 - 2m
2m - 2m = 0:
⇒-n = 8 - 2 m
Multiply both sides by -1:
⇒-n × (-1) = (8 - 2m) × (-1)
⇒n = 2m - 8
The required value of n is equal to n = 2m - 8.
An expression is given in the question ; i.e., 2m - n = 8.
We have to find the value of the 'n' .
What is algebra ?
Algebra is the branch that deals with various symbols and the arithmetic operations such as addition , subtraction , etc.
As per the question ;
The given expression is 2m - n = 8.
Let's solve it to get the value of n.
The value of n can be find out , if we bring n to the left side of equal sign and 8 to the right of equal sign.
So ,
2m - n = 8 can be written as ;
2m = 8 + n
or
n = 2m - 8
Thus , the required value of n is equal to n = 2m - 8.
