Answer:
C. y + 4 = -1/2 (x - 1)
Step-by-step explanation:
The x values go up by 6 units each step, 1, 7, 13, 19.
Start with 1 and add 6 to get 7, then add 6 to get 13, then add 6 to get 19.
For each corresponding step in x, y becomes 3 less.
Start with -4, then subtract 3 to get -7, subtract 3 to get -10, subtract 3 to get -13.
For every change of 6 in x, you get a change of -3 in y. This means a linear relationship.
To find the equation, we can use any two of the given points and the point-slope equation of a line.
y - y1 = m(x - x1)
m = slope = (y2 - y1)/(x2 - x1)
where (x1, y1) and (x2, y2) are two points on the line, and m = slope.
Let's use the points (x1, y1) = (1, -4) and (x2, y2) = (7, -7)
y - y1 = (y2 - y1)/(x2 - x1) * (x - x1)
y - (-4) = (-7 - (-4))/(7 - 1) * (x - 1)
y + 4 = (-7 + 4)/(6) * (x - 1)
y + 4 = (-3/6)(x - 1)
y + 4 = -1/2 (x - 1)

PLEASE ANSWER, FIRST WILL GET A BRAINLIEST, + 2 THANKS (Teaser) An angle that measures 6° is drawn on a piece of paper. You are looking at the angle through a×6 magnifying glass, which means it magnifies by a factor of 6. What is the measure of the angle you see on the paper when you look through the magnifying glass?
Answer: same. ( 6 degree )
Step-by-step explanation:
According to the question, An angle that measures 6° is drawn on a piece of paper. As you are looking at the angle through a×6 magnifying glass, which means it magnifies by a factor of 6 indeed. The length and the width of the shape may magnify by factor of 6, but the degree measure of the angle will remain the same.
Even if it is magnified by a factor of 100, the measure of the angle you see on the paper when you look through the magnifying glass will remain the same.

Answer:
(d) -2x -8 < -44 and -2x -8 ≥ -8
Step-by-step explanation:
A compound inequality is a mathematical sentence that combines two simple inequalities. A solution will satisfy both inequalities. That is, it represents an "and" (intersection) condition for the solution sets.
Equivalent pairAn inequality of the form ...
a > b ≥ c
can be written as a pair of inequalities by considering what is on either side of each of the relation symbols:
left symbol: a > bright symbol: b ≥ cApplicationGiven: -44 > -2x -8 ≥ -8
We can decompose the given inequality into the system ...
-44 > -2x -8 . . . . . . . . left symbol-2x -8 ≥ -8 . . . . . . . . . right symbolWhen we compare these to the offered answer choices, we see that we need to rewrite the first inequality so the constant is on the right:
-2x -8 < -44
Then the equivalent form of the given inequality is ...
-2x -8 < -44 and -2x -8 ≥ -8
__
Additional comment
The transitive property of inequality means that ...
a > b ≥ c
implies that a > c.
You will notice that our given inequality, written in this way, becomes ...
-44 > -8 . . . . . . not true
This means the inequality has no solution. (The solution set is the empty set.)

Paul developed a roll of film containing 36 pictures. If he made 2 prints each of half of the pictures and 1 print of each of the rest, how many prints did he make in all?
Answer:
54
Step-by-step explanation:
Total pictures in the roll = 36
half of the roll = 1/2 of the total pictures in the roll = 1/2 * 36 = 18
Given Paul made 2 prints of each of the half pictures
no. of prints made of half of the pictures = 18*2 = 36
No. of prints left after the half of the roll is printed for two prints= 36-18 = 18
No. of prints made of rest of the pictures 1
Therefore , no of prints made of rest half of pictures = 18*1 = 18
Total prints made = 36 + 18 = 54.
Thus, Paul made 54 prints in all.
On a coordinate plane, a quadrilateral has points W prime (negative 4, 1), X prime (negative 2, 2), Y prime (0, negative 3), and Z prime (negative 4, negative 4). The image of a figure is shown.

Answer:
(3.2, 0.6)
Step-by-step explanation:
[tex]T_{-5.2, 1.4} [/tex] means a translation of (x, y) → (x - 5.2, y + 1.4)
Suppose X has coordinates (a, b), after the translation is applied, X' has coordinates (a - 5.2, b + 1.4). X' is located at (-2, 2), therefore:
a - 5.2 = -2
a = -2 + 5.2
a = 3.2
b + 1.4 = 2
b = 2 - 1.4
b = 0.6

What is the linear function defines the following Arithmetic Sequence? -5, -3, -1, 1, 3, ...
a. an = -5 + 2(n - 1)
b. an = -5 - 2(n - 1)
c. an = 5 - 2(n - 1)
d. an = 5 + 2(n - 1)
Answer:
an = -5 + 2( n-1)
Step-by-step explanation:
The formula for an arithmetic sequence is
an = a1+ d ( n-1)
where a1 is the first term and d is the common difference
a1 = -5 since it is the first term in the sequence
d = term 2 minus term1
= -3 - (-5)
= -3+5 = 2
an = -5 + 2( n-1)

Which function is the result of vertically stretching ƒ(x) = x2 by a factor of 2 and translating it 4 units upward?
Question 20 options:
A)
y = –4x2 + 2
B)
y = 4x2 + 2
C)
y = 2x2 + 4
D)
y = 2x2 – 4
Answer:
The correct answer is the letter C.
Step-by-step explanation:
In order to stretch a function we need to multiply it by the factor we want to stretch, if we want to shrink the function we will have to divide it by the factor. On the other hand in order to translate it we need to sum the factor we want the function to shift. In this case we want to stretch the function by 2, therefore the new function must be 2*f(x), but we also want it to shift by 4 units so it has to be 2*f(x) + 4. Applying the given expression:
[tex]g(x) = 2*f(x) + 4\\g(x) = 2*x^2 + 4[/tex]
The correct answer is the letter C.
Answer:
C
Step-by-step explanation:
y= 2x^2 + 4
When I square my number, I get the same answer as when I multiply my number by 10 and then add 144. My number is positive. What is it?
Answer:
your number is 18
Step-by-step explanation:
x^2 = (x × 10 ) + 144
x^2 = 10x + 144
x^2 - 10x - 144 = 0
using quadratic method
your answer should be
(x- 18) ( x+8 )
What's the equation of the parabola that has its vertex at (8,–14) and a point (5,13) that lies on the curve?
Question 13 options:
A)
y = (x + 8)2 – 14
B)
y = (x – 8)2 – 14
C)
y = 3(x + 8)2 – 14
D)
y = 3(x – 8)2 – 14
Answer:
The expression with the described characteristics is: [tex]y = 3*(x - 8)^2 - 14[/tex]. Therefore the correct answer is letter D.
Step-by-step explanation:
I believe there is a typo in the vertex's coordinate, I think it should be (8,14). I came to this conclusion by observing the possible answers, if the given vertex is correct then there are no correct answers among them. I made my best effort to explain the question in a way that can be generalized for different vertex's coordinates.
The equations are given in their vertex form. This form has the following structure:
[tex]y = a*(x - h)^2 - k[/tex]
Where (h,k) are the vertex's coordinates, in our case (8, 14). This knowledge makes easier to determine a equation with the correct vertex as shown below:
[tex]y = a*(x - 8)^2 - 14[/tex]
Where the value of "a" must be determined by applying the given point.
[tex]13 = a*(5 - 8)^2 - 14\\13 = a*(3)^2 - 14\\a*9 = 27\\a = \frac{27}{9}\\a = 3[/tex]
The expression with the described characteristics is: [tex]y = 3*(x - 8)^2 - 14[/tex]. Therefore the correct answer is letter D.

Ms. White measured the number of the ounces of juice left behind by 3 students after breakfast. She plotted the data on the line plot shown below
Answer: The answer is 7 3/4 :)) <3 have a good day.
The amount of juice left by the three students is (31/4) ounces.
What is dot plot?A dot plot, also called a dot chart, is a type of simple histogram-like chart used in statistics for relatively small data sets where values fall into a number of discrete bins.
Given is that Ms. White measured the number of the ounces of juice left behind by 3 students after breakfast.
The total juice left by 3 students is equivalent to -
{x] = 2 x {2[tex]\frac{1}{4}[/tex]} + 3[tex]\frac{1}{4}[/tex]
{x} = 2 x 9/4 + 13/4
{x} = 18/4 + 13/4
{x} = 31/4
Therefore, the amount of juice left by the three students is (31/4) ounces.
