Consider this sequence of transformations performed on shape I: a dilation by a scale factor of 2, followed by a reflection across the x-axis, and then a translation left 1 unit. Does the sequence prove that shapes I and IV are similar? Explain your answer.
Answer:
The sequence does map shape I onto shape IV. So, the sequence of transformations proves the two shapes are similar.
Step-by-step explanation:
To check whether the sequence proves that shape I is similar to shape IV, check whether the given sequence of transformations maps shape I onto shape IV.
1. Dilate shape I by a scale factor of 2.
2. Then, reflect the dilated shape across the x-axis.
3. Finally, translate the reflected shape 1 unit left.

Dilation by a scale factor of 4 and a reflection over the x-axis
Answer:
(-12, -20).
Step-by-step explanation:
A dilation of factor 4 moves (-3, 5) to (-3*4, 5*4) = the point (-12, 20).
A reflection over the x-axis is (x, y) ------> ( x, -y).
So ( -12, 20) goes to (-12, -20).

[tex] \frac{x + 2}{x + 3} + \frac{x - 3}{x + 2} = \frac{5}{2} [/tex]
[tex] \frac{x + 2}{x + 3} + \frac{x - 3}{x + 2} - \frac{5}{2} = 0[/tex]

[tex] {x}^{2} + 17x + 40 = 0[/tex]
[tex]x = \frac{ - 17± \sqrt{ {17}^{2} - 4 \times 1 \times 40 } }{2 \times 1} [/tex]

pls answer this i need help
Answer:
Step-by-step explanation:
a) Number = x
Multiply it by 3 = 3*x = 3x
Now add 4 to it: 3x + 4
Equation:
3x +4 = 22
b)
3x + 4 = 22
Subtract 4 from both sides
3x + 4 -4 = 22 - 4
3x = 18
Divide both sides by 3
3x/3 = 18/3
x = 6
Answer:
Below in bold.
Step-by-step explanation:
The equation is
3x + 4 = 22
3x = 22 - 4 = 18
x = 18/3
x = 6.
what is the quotient for 68.32 / 2/8
In the function above n is a constant if f(9)=4 what is the value of f(-3)
Answer:
This equation is in y=mx + b form. Just plug in the point to get N, which is also B.
Whatever is in f(x) is your x. So x = 9; This means...
4 = 2/3(9) + n
Solving for n gets you -2.
Now we plug in -3 and also substitute N now that we solved for it.
f(-3) = 2/3(-3) - 2
f(-3) = -4

Latisha’s friend Brandee forgot to make up a test and had these scores: 80%, 92%, 91%, ,75% ,89% ,84% ,0% and . 85% Homework Help ✎
Calculate Brandee’s mean. (Refer to the glossary in the eBook if you do not remember how to do this.) Does this average score really represent her abilities? Why or why not?
Brandee persuaded her teacher, Ms. Juarez, to allow her to make up the missed test. Brandee received a . Calculate her new mean.
What difference did the score make? Does this new mean represent Brandee’s ability more accurately?
Using mean and outlier concepts, it is found that:
Brandee's mean was of 74.5, which doesn't really represent her abilities, as in 7 of the 8 tests she got higher grades than this, but her mean is really affected by the outlier grade of 0%, for the test she missed.Brandee's new mean will be of 85.75, which increases her final grade by 11.25 points, and is a more accurate representation of her abilities, as there is not an outlier grade.--------------------------
The mean of a data-set is the sum of all it's values divided by the number of values.In this question, the data-set is Brandee's grades, that is: 80%, 92%, 91%, ,75% ,89% ,84% ,0% and 85%.--------------------------
There are 8 grades.Thus, the mean is:
[tex]M = \frac{80 + 92 + 91 + 75 + 89 + 84 + 0 + 85}{8} = 74.5[/tex]
Brandee's mean was of 74.5, which doesn't really represent her abilities, as in 7 of the 8 tests she got higher grades than this, but her mean is really affected by the outlier grade of 0%, for the test she missed.
--------------------------
Supposing her grade on the make up test was of 90%, the new mean will be of:[tex]M = \frac{80 + 92 + 91 + 75 + 89 + 84 + 90 + 85}{8} = 85.75[/tex]
Brandee's new mean will be of 85.75, which increases her final grade by 11.25 points, and is a more accurate representation of her abilities, as there is not an outlier grade.

Given f(x) = 3x + 7 and g(x) = 3x, find (f - g)(x).
Answer:
Step-by-step explanation:
(f-g)(x) = f(x)- g(x)
= (3x + 7) - (3x)
= 7
Therefore (f-g)(x) = 7
Answer:
(f - g)(x) = 7
Step-by-step explanation:
Here, we should subtract the two functions:
f(x) = 3x + 7 and g(x) = 3x
(f - g)(x) = 3x + 7 - 3x
= 3x - 3x + 7
= 7
Hence, (f - g)(x) = 7

Answer:
147
Step-by-step explanation:
If you add up all the angles you have, you get 933. Since an octagon has 1080 degree angles the last angle must be added to 933 to make it equal to 1080. If you subtract 933 from 1080, you get the remaining angle 147.

Given:
f(x) = 2x + 5 g(x) = x²h(x) = -2xTo find h(g(f(x))) first find g(f(x)), substitute x with f(x):
g(f(x)) = g(2x + 5)Since g(x) = x², the value of g(2x + 5) is:
g(f(x)) = (2x + 5)²Now, the next step:

Write first four terms of an AP when the first term is -2 and common difference is O.
Explanation:
If the common difference is 0, then we're adding 0 to each term to get the next term. However, adding 0 doesn't change the number. So that's why we have the same thing written four times.
As another example, let's say the common difference was 1 instead of 0. That would mean the first four terms are -2, -1, 0, 1 since we add 1 to each term to get the next one (eg: -2+1 = -1).
Answer:
-2, -2, -2, -2.
Step-by-step explanation:
If the common difference (d) is 0 then all terms are the same as the first:-
AP = a, a + d, a + 2d, a + 3d
Here we have -2, -2+0, -2 + 2(0), -2 + 3(0)
