Is there an image, or shape that this is?
Given the two points (-12, 18) and ( 24, -54) what is the slope?
Answer:
Slope = -2
Step-by-step explanation:
Use the equation to find a slope:
y2-y1/x2-x1 = slope
-54 - 18 = -72
24 - (-12) = 36
-72/36= -2
(7-6i)(7+6i) please show me how you got the answer step by step thankkksss
Answer:
Just cross multiply
48+42i-42i-36i
then your final answer is: 48-36i

Has the marrying age of a man changed over the years? The United States Bureau of the Census takes a formal count of everyone in the U.S. every 10 years and has provided the following data that gives the median age of an American man at the time of his first marriage.
What does it mean in this situation if the average rate of change is negative?
a.
It means that the median age of a man at the time of his first marriage is increasing.
b.
It means that the median age of a man at the time of his first marriage is decreasing.
c.
It means that the median age of a man at the time of his first marriage has a constant rate of change.
d.
There is no way to determine the average rate of change in this situation.
The Answer is D
Answer:
If the average rate of change in the data is negative, based on the variables analyzed;
b. It means that the median age of a man at the time of his first marriage is decreasing
Step-by-step explanation:
The given data is presented as follows;
Year; [tex]{}[/tex] 1910, 1920, 1930, 1940, 1950, 960, 1970, 1980, 1990, 2000
Median Age; [tex]{}[/tex] 25.1, 24.6, 24.3, 24.3, 22.8, 22.8, 23.2, 24.7, 26.1, 26.8
The date points are plotted on a graph using Microsoft Excel
[tex]The \ average \ rate \ of \ change = \dfrac{The \ change \ in \ the \ median \ age}{The \ corresponding \ change \ in \ years \ (always \ +ve)}[/tex]The corresponding change in years, Δx, is positive because, we have;
Δx = x₂ - x₁ = Higher year - Previous year
Therefore, for a negative average rate of change, we have;
[tex]The \ average \ rate \ of \ change = -ve = \dfrac{The \ change \ in \ the \ median \ age}{+ve}[/tex]
∴ The change in the median age, Δy = +ve × (-ve) = -ve (negative)
Δy = -ve
∴ Δy = Median age for higher year - Median age for previous year = -ve
Median age for higher year = -(y) + Median age for previous year
Where 'y' is positive
∴ Median age for subsequent year < Median age for previous year
Therefore, if the average rate of change is negative, the median age of a man's first marriage is decreasing

A polynomial function with zeros 1,6i, and -6 i is
Step-by-step explanation:
If -5 is a zero, then one of the factors must be (x+5). Typically, a problem will give you one complex root (zero), but you must infer that its conjugate is always another root. In this case, since 2+6i is a root, then 2-6i must also be a root.
Those factors must then be (x-(2+6i)) and (x-(2-6i))
To get the final polynomial, multiply the factors together: (x+5)(x-2-6i)(x-2+6I)
I would multiply the complex factors first since they will typically simplify to a more workable expression.
(x - 2 - 6i)(x - 2 + 6i) = x2 - 2x + 6xi - 2x + 4 - 12i - 6xi + 12i - 36i2
= x2 - 4x + 40
Then multiply this trinomial by the final factor: (x2 - 4x + 40)(x + 5)
= x3 + 5x2- 4x2- 20x + 40x + 200
= x3 + x2 + 20x + 200
To get a coefficient of 3, multiply this polynomial by 3.
3(x3 + x2 + 20x + 200) = 3x3 + 3x2 + 60x + 600
Answer: 3x3 + 3x2 + 60x + 600

Over what interval is the function in this graph increasing
Answer:
C. -4 <= x <= 1
Step-by-step explanation:
The function increases where the slope of the line is up to the right, a positive slope. That only happens in the interval -4 <= x <= 1.
Answer: C. -4 <= x <= 1
how do you do this!???
Answer:
x=2
Step-by-step explanation:
assuming this shape is euclidean (don't pay attention to this just some extra info, assume that all triangles on a sheet of paper have angles summing to 180)
The sum of all angles in a triangle is 180, so
90+60+15x=180
150+15x=180
15x=30
x=2

Chris deposited $1,000 into an account that earned 8% compound interest over 48 months. What is the account value earned after 48 months?
Answer:
She would have $1080 dollars in 48 months.
Step-by-step explanation:
So she earned 8% interest in 48 months.
So you find 8% of 1000 and that would be 80 and add 80 to 1000 because she gained 80 dollars in interest over 48 months so in 48 months she has $1080 dollars.

1699
Answer:
A) 11°
Step-by-step explanation:
All triangles equal 180, so:
102 + 67 + x = 180
169 + x = 180
x = 11

A number when divided by 5 gives 0 as remainder, that number when divided by 7 gives 0 as remainder also. What will be the remainder when that number is divided by 35?
Answer:
zero
Step-by-step explanation:
The computation of the remainder when the number would be divided by 35
Let the number be x
So if x is divided by 5 gives the remainder 0
x = 0
And, if x is divided by 7 gives the remainder 0
x = 0
So if x is divided by 35 so the remainder is also zero
Select all the equations where x = 4 is a solution.

mrs susan bought 1/8 8m of curtain choth she used 3/5 m to make a curtain for the living room window how many meters of choth we're not use
Answer:
[tex]\frac{19}{40}[/tex]
Step-by-step explanation:
The computation of the meters of cloth that were not use is shown below:
= Used for making a curtain - purchase of curtain cloth
[tex]= \frac{3}{5} - \frac{1}{8}\\\\= \frac{24 - 5}{40} \\\\= \frac{19}{40}[/tex]
Hence, the meters of cloth that was not used is [tex]\frac{19}{40}[/tex]

Answer:
D. x plus y and x minus y plus 2y
x + y
x + y
Step-by-step explanation:
2y minus four and 2y minus four plus 9
