ANSWER TO PART A
The mapping for the reflection in the line [tex]y=x[/tex], is given by
[tex](x,y)\rightarrow (y,x)[/tex].
That is the coordinates swap position .
The only way we can construct a function [tex]f(x)[/tex], such that;
[tex](x, f(x))\rightarrow (f(x),x)[/tex] are equal is when
[tex]f(x)=x[/tex].
So that when [tex]x=a, f(a)=a[/tex] .
The mapping then becomes
[tex](a,a)\rightarrow (a,a)[/tex].
Therefore the function, [tex]f(x)=x[/tex] is the function whose reflection in the line
[tex]y=x[/tex] is itself.
ANSWER TO PART B
The function is symmetrical with respect to the origin. That is to say the function is an odd function.
A function is symmetric with respect to the origin, if it satisfies the condition,
[tex]f(-x)=-f(x)[/tex]
For instance,
[tex]f(a)=a[/tex]
[tex]f(-a)=-a[/tex]
Since
[tex]f(-a)=-a=-f(a)[/tex]
We say the function is symmetric with respect to the origin.
Tony is writing a fraction equivalent to 2/7 using the formula 2*m/7*n. Which statement about m and n must be true so that tony fraction has the same value as 2/7
A. M/n has to be greater than 1
B. M/n has to equal 7
C. M/n has to be greater than 2
D. M/n has to equal 1
the answer is A i think
hope it helps
Answer:
Step-by-step explanation:
Given that Tony is writing a fraction equivalent to [tex]\frac{2}{7}[/tex] using the formula [tex]\frac{2}{7} *\frac{m}{n}[/tex]
Since this is equal to 2/7
we must have the value of [tex]\frac{m}{n} =1[/tex]
Hence option D is right.

the water was pumped out of a backyard pond.what is the domain this graph?
Answer:
C) Real numbers from 0 to 8.
Step-by-step explanation:
We have been given a graph between depth (dependent variable) and time (independent variable). We need to figure out the domain of the given graph.
We know that domain is the set of values of independent variable for which the graph produces a finite value of dependent variable.
From the graph, we can see that for values of time between 0 and 8 minutes, the graph produces a finite value of depth. Therefore, domain of the given graph is all real numbers between 0 and 8 (inclusive).
Is this correct??please tell me
7(4n-6)= - 182
28n-42= -182
+42 +42
28n/28= -140/28
n= -5
This is incorrect, 7x4n=28n and -7x6=-42. There is no way to get -182.

The table displays the total cost, y, of purchasing x tickets for the carnival. Which conclusions can you draw from the data shown in the table? Select all that apply. Twelve tickets cost $30.00. Thirty tickets cost $12.00. Each additional ticket costs $2.50. The table is a partial representation. (27.50, 11), (30, 12) and (32.50, 13) are the ordered pairs represented in the table.
Answer:
Twelve tickets cost $30.00.
Each additional ticket costs $2.50.
The table is a partial representation.
Answer:
A C D
Step-by-step explanation:
If 2x=8 what does "x" equal?
1.Hannah walked the same number of miles each day for 5 days. Let m represent the total number of miles Hannah walked. Write a linear expression for the total number of miles she walked.
2.Jimmy brought 2 books per day to the book drive. Peter brought 4 books per day to the book drive. Let d represent the number of days of the book drive. Write a linear expression to represent the total number of books they brought.
3.Patricia buys clothes that are on sale with a 30% discount. Let c represent the cost of the clothes. Write a linear expression for the cost of the clothes.
4.A family of four had dinner together at a restaurant. Write two expressions for calculating their total bill if they leave a 15% tip. Let c represent the cost of their meal before tipping.
5.Tommy has $40 in his pocket. He sees a pair of pants that cost $37 and wants to buy them. If there's 10% sales tax where Tommy lives, can he afford to buy the pants? Write a linear expression and use it to solve the problem.
6.Add the expressions x + 18 and 3x − 12.
7.Subtract 3x − 4 from 5x + 7.
8.Subtract −4x + 1 from x − 2.
1) Given m represent the total number of miles Hannah walked.
Let us assume Hannah walked x miles each day.
So total number of miles Hannah walked in 5 days is m=5x.
2)Given Jimmy brought 2 books per day and Peter brought 4 books per day.
If d is the number of days the book drive, total number of books they brought
=total number books brought by Jimmy+ total number of books brought by Peter
= 2d+4d = 6d
3) Given that c represent cost of the clothes.
Then 30% discount = 0.3c
Hence cost of the clothes = c-0.3c = 0.7c
4) Given c represent the cost of their meal before tipping.
And tip is 15% of the cost.
Hence tip = 0.15c
Hence total bill = c+0.15c=1.15c
5) Given that Tommy had 40$ in his pocket.
And pair of pants cost 37$ with 10% sales tax.
Hence cost of pants including sales tax = 37+37*0.1 = 40.1$ >40$
Hence Tommy cannot afford the pants with 40$ in his pocket.
For following problems, we should group the like terms together and then simplify.
6) (x+8)+(3x-12) = (x+3x)+8-12 = 4x-4
7) 5x+7-(3x-4) = 5x+7-3x+4 = (5x-3x)+7+4 = 2x+11
8) (x-2)-(-4x+1)=x-2+4x-1 = (x+4x)-2-1 = 5x-3

1340 units²
There are 2 rectangles 25 × 12, 2 rectangles 25 × 10 and 2 rectangles 12 × 10
SA = 2(25 × 12) + 2(25 × 10) +2(12 × 10)
= 600 + 500 + 240 = 1340 units²
The length of a rectangle is three times it’s width. It’s area is 75 inches squared. Find the length and width of the rectangle
The answer is 225 because 75x3 =225
Final answer:
The length of the rectangle is 15 inches and the width is 5 inches, determined by setting up an equation using the given conditions that the area is 75 square inches and the length is three times the width.
Explanation:
The question asks us to find the length and width of a rectangle given that the length is three times the width and the area of the rectangle is 75 square inches. To solve this, let's denote the width of the rectangle as w inches. The length would then be 3w inches since it is three times the width. The area of a rectangle is found by multiplying the length and width, so we can write the equation:
Area = length × width
75 = 3w × w
To find the width (w), we need to solve the quadratic equation:
w² × 3 = 75
w² = 75 / 3
w² = 25
To find w, we take the square root of 25, which gives us:
w = 5 inches
Now that we have the width, we can easily find the length by multiplying the width by 3:
Length = 3 × 5
Length = 15 inches
Therefore, the width of the rectangle is 5 inches and the length is 15 inches.

1+2g=-7 how do you do this?
Answer:
you would - 1 to -7 and get -8 then divide -8 by -2 than it would be 4
Step-by-step explanation:
I like my equations to have the variable before the constant.
2g+1=-7
Subtract 1 from the left side. Remember, whatever you do on one side, you MUST do it on the other.
2g=-8
Divide 2 from BOTH sides.
g=-4

A designer wants to make a circular fountain inside a square of grass as shown at the right. What is a rule for the area A of the grass as a function if r
Answer:
[tex]A=4r^{2}-r^{2}\pi[/tex]
Step-by-step explanation:
1. To calculate the area of the grass you must substract the area of the square and the area of the circle.
2. The area of the square is:
[tex]A1=L^2[/tex]
Where [tex]L[/tex] is one side of the square.
3. You have that:
[tex]L=2r[/tex]
4. Therefore:
[tex]A1=(2r)^{2} =4r^{2}[/tex]
5. The area of the circle is:
[tex]A2=r^{2}\pi[/tex]
6. The are of the grass is:
[tex]A=4r^{2}-r^{2}\pi[/tex]

all numbers that have 9 as a factor also have 2 as a factor ?
True or False
Numbers with factors of 9:
18, 27, 36, 45, 54, 63, 72, 81
18, 36, 54 and 72 may have factors of 2, but the other do not.
This means that not all numbers with 9 as a factor will also have 2 as a factor.

Find the value of x that makes m || n
Answer:
[tex]107^\circ, 133^\circ, 20^\circ, \text{and}, 23^\circ[/tex]
Step-by-step explanation:
9. For the lines 'm' and 'n' to be parallel the sum of interior angles should be 180 degrees that is:
[tex]x+73^\circ=180^\circ[/tex]
[tex]x=107^\circ[/tex]
10. For the lines 'm' and 'n' to be parallel the alternate exterior angles should be equal that is:
[tex]147^\circ=x+14^\circ[/tex]
[tex]x=147^\circ-14^\circ[/tex]
[tex]x=133^\circ[/tex]
11. For the lines 'm' and 'n' to be parallel alternate angles should be equal that is:
[tex]180^\circ-3x=2x+20^\circ[/tex]
Solving for 'x' we get:
[tex]180^\circ-20^\circ=3x+2x[/tex]
[tex]5x=160^\circ[/tex]
[tex]x=32^\circ[/tex]
12. For the lines 'm' and 'n' to be parallel corresponding angles should be equal that is:
[tex](7x-11)^\circ=(4x+58)^\circ[/tex]
[tex]7x-4x=58^\circ+11^\circ[/tex]
[tex]3x=69^\circ[/tex]
[tex]x=\frac{69}{3}=23^\circ[/tex]

Hey there! :)
Answer: x = 9.4
Step-by-step explanation : How do we know this? Well, let's first rewrite our question.
(-16.1) · 9.4 · (-7.2) = x · (-7.2) · (-16.1)
Let's multiply everything out.
