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

what is - 4i ^ 19, simplify
Answer:
[tex]"i"[/tex]
Step-by-step explanation:
[tex]i =\sqrt{-1} \\i^{2}= -1\\\\i^{3}= -i\\\\i^{4}= 1\\\\i^{5}= i\\[/tex]
the cycle repeats every 4
19/4 = 4.75
16 is divisible by 4 plus three more
thus [tex]i^{19} = -i[/tex] but you problem has a minus in front so "i"

Emma had 10 Balls in a bag. The balls were numbers 1 through 10. She wanted to test the probability of drawing a ball that is a multiple of 3.
Also, write a prediction about if there is an unlikely, impossible, likely, even, or certain change of drawing a multiple of 3.
Answer:
30%UnlikelyStep-by-step explanation:
The balls - multiples of 3 are:
3, 6 and 9The probability of a multiple of 3 is:
3 out of 10 orP = 3/10 = 30%30% probability is in the range 0%-50% so this event is unlikely
Total multiples=3
[tex]\\ \sf\longmapsto P(3)=\dfrac{Multiples\:of\:3}{Total \:balls}[/tex]
[tex]\\ \sf\longmapsto P(3)=\dfrac{3}{10}[/tex]
[tex]\\ \sf\longmapsto P(3)=30\%[/tex]
It is <50%;So it is unlikely to happen.

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.
Answer:
The sequence does map shape I onto shape IV. So, the sequence of transformations proves the two shapes are similar.

5-2x=-4x+9
Answer step by step
Answer:
x = 2
Step-by-step explanation:
5-2x = -4x+9
5+(-2x+4x) = (-4x+4x)+9 [Add 4x to each side to get ride of 4x on the right]
5+2x = 9
(5-5)+2x = (9-5) [subtract 5 from both sides to get rid of 5 on the left]
2x = 4
2x/2 = 4/2 [Divide each side by 2 to get x alone]
x=2
The solution to the equation 5 - 2x = -4x + 9 is x = 2.
Here, we have,
To solve the equation 5 - 2x = -4x + 9 step by step, we will combine like terms and isolate the variable x.
Here's how:
Start by simplifying both sides of the equation by combining like terms:
5 - 2x = -4x + 9
The left side has no like terms to combine, so we move to the right side:
-2x + 4x = 9 - 5
Simplifying further:
2x = 4
Now, we want to isolate the variable x.
To do that, we need to get rid of the coefficient 2 that is multiplied by x.
We can achieve this by dividing both sides of the equation by 2:
(2x)/2 = 4/2
Simplifying further:
x = 2
We have found the solution for the variable x.
Therefore, the solution to the equation 5 - 2x = -4x + 9 is x = 2.

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).

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)
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.

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

if 1kg is 1.00g then 3kg is 2.500g
Answer:
I Kg = 1000 g
3 Kg = 3000 Kg
Step-by-step explanation:
Kg - Hg - Dag - g
1 Kg - 10 Hg - 100 Dag - 1000 g
So, 1 Kg = 1000 g
3 Kg = 3(1000)g = 3000 g
Sixteen is equal to 7 increased by the product of 3 and a number.
Answer:
number is 3
Step-by-step explanation:
let the number be n then the product of 3 and the number is 3n , so
16 = 7 + 3n ( subtract 7 from both sides )
9 = 3n ( divide both sides by 3 )
3 = n
That is the number is 3
