Answer:
-14
Step-by-step explanation:
Answer:
-14, fourth choice
Step-by-step explanation:
absolute value is represented with this |x|, the 2 lines
The absolute value for a real number, in this case -14, is the non-negative value without regard to its sign. So the absolute value of -5 would be 5, and the absolute value of 7 would still be 7
In this case there's no 14, so u can choose -14

What is the value of the 30th term in the following arithmetic sequence?
12, 6, 0, -6, ...
a. 186
b. -162
c. -186
d. 342
Answers
Because to find the nth term you need to see the pattern . It’s going down in -6 so -6n , then you do inverse to the first number , so +6 to 12 =18 . This makes -6n +18 . This is your formula just substitute n for 30 and you will get -162.
-6 x 30 = -180 , -180 + 18+ -162

Mateo’s aunt bought a share of stock many years ago.
The value of the stock increased by 80%.
Its value is now $270.
What was the value of the stock when Mateo’s aunt bought it?
Answers
The stock has increased 80% hence it is now worth 180%.
Find the original 100%.
First find 1% (Divide by 180)
$270/180 = $1.50
Now find 100% (Multiply by 100)
$1.50 X 100 = $150
The answer is $150
The value of the stock when Mateo’s aunt bought it was $150.
What is the fundamental principle of multiplication?Multiplication is the mathematical operation that is used to determine the product of two or more numbers. If an event can occur in m different ways and if following it, a second event can occur in n different ways, then the two events in succession can occur in m × n different ways.
We need to find the value of the stock when Mateo’s aunt bought it.
Given that the value of the stock increased by 80%. Its value is now $270.
The stock has increased 80% thus it is now worth 180%.
Then Divide by 180;
$270/180 = $1.50
Now find 100% then Multiply by 100;
$1.50 X 100 = $150
The value of the stock when Mateo’s aunt bought it was $150.

please help ~~ and if you could, please explain what a constant of proportionality is :)
Answers
Answer:
The answer is D. k=5
Step-by-step explanation:
The constant of proportionality is just the rate the x increases or decreases at. The x is increasing by 5 over time so the COP or rate is 5.
Answer:
The answer is D: K=5
Step-by-step explanation:
The constant of proportionality is the ratio between two directly proportional quantities. Two quantities are directly proportional when they increase and decrease at the same rate. The constant of proportionality k is given by k=y/x where y and x are two quantities that are directly proportional to each other.
So, what you do is that you get the first number, which is 5/25. Simplify it and divided to get it as low as possible, if you do that, you would get 1/5 and 1/5 can also mean 5/1 in these situations. So your basic answer is 5.

Quadrilateral ABCD was dilated with the origin as the center of dilation to create quadrilateral EFGH on the graph below.
Which rule best represents the dilation that was applied to quadrilateral ABCD to create quadrilateral EFGH?
Answers
Option D is correct (x, y) → (2.5x, 2.5y).
What are coordinates?A pair of numbers called coordinates are used to locate a point or a form in a two-dimensional plane. The x-coordinate and the y-coordinate are two numbers that define a point's location on a 2D plane.
Given, Quadrilateral ABCD was dilated with the origin as the center of dilation to create quadrilateral EFGH on the graph below.
Since Scale factor:
A scale factor is defined as the ratio between the scale of a given original object and a new object, which is its representation but of a different size (bigger or smaller).
In our case,
A dilation of 2.5 because side AB is 4 units and EF is 10 units and if you divide 10/4 will get you with your scale factor.
thus, Scale factor is 2.5
Therefore, best represents the dilation that was applied to quadrilateral ABCD to create quadrilateral EFGH is D. (x, y) → (2.5x, 2.5y)

Answer:
1/5
1/3
Step-by-step explanation:
For the first problem:
5/7 of ... is 1/7
so
5/7 of x is equal to 1/7
so
(5/7)x = (1/7)
so
x = (1/7)/(5/7)
so
x = 1/5
For the second problem:
5/7 of ... is 5/21
so
5/7 of x is equal to 5/21
so
(5/7)x = (5/21)
so
x = (5/21)/(5/7)
so
x = 1/3
