Answer:
Since dilation is not mentioned in the answer options, thus, the correct option is 'None of the above'.
Step-by-step explanation:
We know that when an object is dilated by a scale factor, it gets reduced, stretched, or remains the same, depending upon the value of the scale factor.
If the scale factor > 1, the image is enlarged If the scale factor is between 0 and 1, it gets shrunk If the scale factor = 1, the object and the image are congruentThe figure seems to have enlarged by a certain scale factor. Thus, the figure b is a result of dilation of the original figure by a certain scale factor.
Rotation, Reflection, and translation do not affect the size of the original figure.
Since dilation is not mentioned in the answer options, thus, the correct option is 'None of the above'.
Which ordered pair represents y as a function of x?
A. {(−2, 0), (−1, 0), (−1, 1), (0, 2)}
A. {(−2, 0), (−1, 0), (−1, 1), (0, 2)}
B. {(0, 1), (1, 3), (2, 5), (3, 7)}
B. {(0, 1), (1, 3), (2, 5), (3, 7)}
C. {(−1, 4), (−1, 6), (0, 4), (1, 8)}
C. {(−1, 4), (−1, 6), (0, 4), (1, 8)}
D. {(9, 5), (9, −5), (11, 7), (11, −7)}
Answer:
B
Step-by-step explanation:
Here, we want to select an option that represents y as a function of x
We simply want to select an option which is a function
Now, the answer in this case is one in which there are no repeating values of x and y
What this means is that all x values and all y values exactly have a single relationship between each of them
No y values has two x values and no x values links to 2 y-values
With this in mind, the correct answer is ;
option B

Answer:
x = - [tex]\frac{1}{5}[/tex], x = 5
Step-by-step explanation:
Given
[tex]\frac{x+1}{x-1}[/tex] - [tex]\frac{x-1}{x+1}[/tex] = [tex]\frac{5}{6}[/tex]
Multiply through by 6(x - 1)(x + 1) [ the LCM of the denominators ]
6(x + 1)² - 6(x - 1)² = 5(x - 1)(x + 1) ← expand factors and simplify
6(x² + 2x + 1) - 6(x² - 2x + 1) = 5(x² - 1)
6x² + 12x + 6 - 6x² + 12x - 6 = 5x² - 5
24x = 5x² - 5 ( subtract 24x from both sides )
0 = 5x² - 24x - 5 ← in standard form
0 = (x - 5)(5x + 1) ← in factored form
Equate each factor to zero and solve for x
5x + 1 = 0 ⇒ 5x = - 1 ⇒ x = - [tex]\frac{1}{5}[/tex]
x - 5 = 0 ⇒ x = 5
finish the table and write the equation

What’s the answer ?? The triangle says 84 degrees
Answer:
x = 48°
Step-by-step explanation:
x + x + 84° = 180°
2x = 180° - 84°
2x = 96°
x = 96°/2
x = 48°
Answer:
84+2a=180
2a=180-84
= 96
2a=96/2
=48
So, each angles are 48 degrees.

Help pls I am in 4th and my sister is at school so she can't help pls I was sick when we learned this I need like a couple more and then I can do the rest :(
Answer:
3/20
Step-by-step explanation:
you multiply 1/4 and 2/5 to get the answer
did I get this answer right?
Answer:
Yes
Step-by-step explanation:
Yes
Answer:
No, the answer is suppose to be 9.
Step-by-step explanation:
if you did 54 divided by 18 you would get 3. so if you do 54 divided by 3 you would get 18. then if you do 27 divided by 3 it would equal 9.
so therefore your answer will be 9.

Answer: C) All real values of x such that [tex]x \le 0[/tex]
In other words, x must be 0 or smaller.
===================================================
Explanation:
The reason why is because we must make the stuff under the square root to never be negative. We must make -2x be 0 or larger.
So,
[tex]-2x \ge 0 \\\\-2x+2x \ge 0+2x \ \text{ ... add 2x to both sides}\\\\0 \ge 2x\\\\2x \le 0 \ \text{ ... flip both sides, and the inequality sign}\\\\x \le 0/2 \ \text{ ... divide both sides by 2}\\\\x \le 0[/tex]
As an example, if x = -2, then -2x = -2(-2) = 4 is positive. Applying the square root to a positive number is valid.
But if x = 5, then -2x = -2*5 = -10 is under the square root, which is not allowed.

a. Harry started a new job where he earns the same amount every hour. Last week, he worked 9 hours and earned $108. Write the linear equation for this situation, where y represents the money earned, in dollars, and I represents the number of hours worked.
Answer:
I=12
Step-by-step explanation:
y=108
I=108/9
I=12
Answer:
y = 12lStep-by-step explanation:
This is the proportional relationship
Let the equation be:
y = rl, where y- money earned, l- number of hours, r- hourly rateWe have:
108 = 9rr = 108/9r = 12The required equation is:
y = 12lPlease help

The following chart shows the number of rows in an auditorium and the total number of seats. What equation defines the number of seats with respect to the number of rows.
a) S=20R+100
b) S=40R+120
c) S=20R+60
d)S=20R
Answer:
Answer: c) S=20R+60
Step-by-step explanation:
Linear Model
The chart supplied shows the number of rows (R) in an auditorium and the total of seats (S).
We'll find the equation that relates them. The equation of a line can be expressed in the slope-intercept form:
S = mR + b
Where m is the slope and b is the intercept.
The slope is found by:
[tex]\displaystyle m=\frac{S_2-S_1}{R_2-R_1}[/tex]
We'll use two sample points (20,460) and (45,960):
[tex]\displaystyle m=\frac{960-460}{45-20}=\frac{500}{25}[/tex]
m = 20
The value of b can be found by using one of the points, for example (20,460), and having m=20:
460 = 20*20 + b
Thus: b = 460 - 400 = 60.
The equation is:
S = 20R + 60
You can test the other points and check they belong to the same line.
Answer: c) S=20R+60
I already finished it but how do you know if it’s decreasing or increasing?
Please explain to me :)
Answer:
If the slope is positive it is increasing if the slope is negative it is decreasing :)
Example:
Y=mX+b
If m is positive it is a positive slope

What is the equation of the line that passes through the point (-2,-2) and has a
slope of 4?
the domain of y=log(9-x^2),xER, is
Step-by-step explanation:
log(z) is defined when z > 0.
For log(9 - x²) to be defined, we have 9 - x² > 0.
=> x² < 9, -3 < x < 3.
The domain of y = log(9 - x²) is (-3,3).
Giving 40 points PLEASE help ASAP The ratio of the number of teachers to students in a school is 3:35. The ratio of male students to the number of female
students is 2:5. There are 500 female students. How many teachers are there?
In the box, type the answer and tell how you found it. You may also do your work on a separate sheet of paper and upload it
in the box below.
Answer: 500 female students. 2:5 ratio for males means 200 male students. 500 female plus 200 male equals 700 students total. There are three teachers for every 35 students, so 700/35 multiplied by three equals 60 teachers.
