The coordinates of the vertices of the image of the triangular figure with vertices (-5, -3), (-2, -9), (-5, -8) are the points (3, 3), (6, -5), (7, -2)
What is a reflection transformation?A reflection transformation is one in which the image points are mirrored about a line of reflection.
The coordinates of the vertices of the triangle following a reflection about the line y = -2·x - 3 can be found as follows;
The coordinates of the vertices of the triangle are; (-5, -3), (-2, -9), (-5, -8)
The slope of the line y = -2·x - 3 is m₁ = -2, therefore, the slope, m₂ of the line of reflection is m₂ = -1/(-2) = 1/2
The equations of the line of reflection are therefore;
y = (1/2)·(x + 5) - 3 = 0.5·x - 0.5
y = 0.5·x - 0.5
The point of intersection can therefore be found as follows;
0.5·x - 0.5 = -2·x - 3
Which indicates, using an online calculator, x = -1
y = 0.5 × (-1) + 0.5 = 0
The point of intersection of the line from (-5, -3) to the image and the line of reflection is (-1, 0)
(x₁ + x₂)/2 = -1
(-5 + x₂)/2 = -1
x₂ = 3
Similarly; (y₁ + y₂)/2 = 0
(-3 + y₂)/2 = 0
y₂ = 3
The image of the point (-5, -3) following a reflection is (3, 3)
Equation of the line from point (-2, -9) is; y = 0.5·(x + 2) - 9
y = 0.5·x + 1 - 9 = 0.5·x - 8
The point of intersection is; 0.5·x - 8 = -2·x - 3
Which indicates x = 2 and y = -7
(x₁ + x₂)/2 = 2
(-2 + x₂)/2 = 2
x₂ = 6
Similarly; (y₁ + y₂)/2 = -7
(-9 + y₂)/2 = -7
y₂ = -5
The coordinate of the point (-2, -9) following a reflection about the line y = -2·x - 3 is (6, -5)
The equation from the perpendicular line to the line of reflection from the point (-5, -8), is; y = 0.5·(x + 5) - 8 = 0.5·x + 2.5 - 8 = 0.5·x - 5.5
y = 0.5·x - 5.5
The point of intersection with y = -2·x - 3 is therefore at the point; 0.5·x - 5.5 = -2·x - 3
x = 1
y = -5
(x₁ + x₂)/2 = 1
(-5 + x₂)/2 = 1
x₂ = 7
Similarly; (y₁ + y₂)/2 = -5
(-8 + y₂)/2 = -5
y₂ = -2
The coordinate of the point (-5, -8) following a reflection about the line y = -2·x - 3 is (7, -2)

Find the distance between the two points in simplest radical form.
(-5,8) and (-3, 1)
Given:
The two points are (-5,8) and (-3,1).
To find:
The distance between the given two points in simplest radical form.
Solution:
Distance formula: The distance between two points is
[tex]d=\sqrt{(x_2-x_1)^2+(y_2-y_1)^2}[/tex]
Using distance formula, the distance between (-5,8) and (-3,1) is
[tex]d=\sqrt{(-3-(-5))^2+(1-8)^2}[/tex]
[tex]d=\sqrt{(-3+5)^2+(-7)^2}[/tex]

What is the average rate of change of f(x), represented by the table of values, over the interval [-3,4]
Answer:
Average rate of change = 3
Step-by-step explanation:
We know that the average rate of change is basically a measure of the slope of the secant line in the closed interval [a, b].here a = -3 and b = 4
f(b) = f(4) = 27f(a) = f(-3) = 6⇒ Average rate of change = f(b) - f(a) / b - a
= (27 - 6) / (4 - (-3))
= 21 / 7
= 3
Therefore, Average rate of change = 3

What is the image point of (7,-5)(7,−5) after a translation right 3 units and down 1 unit?
Answer:
The translated image point would then be (10, -6) (10, -6)
Step-by-step explanation:
The image point of (7,-5)(7,−5) after a translation right 3 units and down 1 unit is (4,-6)(4,−6)
What is translation?A translation is a type of transformation that takes each point in a figure and slides it the same distance in the same direction.
Now the given points are,
(7,-5)(7,−5)
So, when the image points translates right 3 units there is change in x coordinate. Thus,
(7,-5)(7,−5)
= (7-3,-5) (7-3,−5)
= (4,-5)(4,−5)
and, when the image points translates down 1 unit there is change in y coordinate. Thus,
(4,-5)(4,−5)
= (4,-5-1)(4,−5-1)
= (4,-6)(4,−6)
Thus, the image point of (7,-5)(7,−5) after a translation right 3 units and down 1 unit is (4,-6)(4,−6).

Using proportions, we have that:
6. From the last pool, 46.43% of voters were for the candidate.
7. Janie makes the triple amount of Jenny.
8. The balance has increased by 3.02% during the year, not 3%.
9. The statement that 10% of the students in the class are men with blond hair is correct.
10. There is a intersection between the percentages of Democrats and of union members, hence we can not affirm that the sets are independent and that 18% of the voters are Democrats who are union members.
What is a proportion?A proportion is a fraction of a total amount, and the measures are related using a rule of three. Due to this, relations between variables, either direct(when both increase or both decrease) or inverse proportional(when one increases and the other decreases, or vice versa), can be built to find the desired measures in the problem, or equations to find these measures.
For item 6, we have that:
A 40% increase is represented by 1.4x.The resulting percentage is of 65%.Hence:
1.4x = 65
x = 65/1.4
x = 46.43%.
From the last pool, 46.43% of voters were for the candidate.
For item 7, we have that 200% more than a measure is given by:
x + 2x = 3x.
As the measure by itself is of 100%, hence:
Janie makes the triple amount of Jenny.
For item 8, we have that:
The 1% increase on the first semester is represented by 1.01.The 2% increase on the second semester is represented by 1.02.Hence the yearly increase is given by:
1.01 x 1.02 = 1.0302 = 3.02%.
The balance has increased by 3.02% during the year, not 3%, because the 2% increase on the second semester is over the 1% increase in the first semester, hence the coefficients are multiplied.
For item 9, we have that:
50% of the students are men.Of the men(50%), 20% have blond hair.Hence:
0.2 x 0.5 = 0.1.
The statement that 10% of the students in the class are men with blond hair is correct.
For item 10, we have that:
45% of the voters are Democrats.40% of the voters are union members.There is a intersection between the percentages of Democrats and of union members, hence we can not affirm that the sets are independent and that 18% of the voters are Democrats who are union members.

We have a translation 3 units downwards and 4 units to the right. So the equation is:
g(x) = ∛(x - 4) - 3
What is the equation for the function g(x)?
We know that g(x) is a transformation of the parent cube function, which is f(x) = ∛x
If we look at the image, we can see that the graph of g(x) is exactly like the graph of f(x), but translated 3 units downwards and 4 units to the right.
A vertical translation of N units is written as:
g(x) = f(x) + N
if N > 0, the translation is upwards.If N <0, the translation is downwards.A translation of 3 units downwards is written as:
g(x)= f(x) - 3
A horizontal translation of N units is written as:
g(x) = f(x + N)
if N > 0, the translation is to the left.If N <0, the translation is to the right.Then a translation of 4 units to the right is:
g(x) = f(x - 4) - 3
Replacing the function f(x) we get:
g(x) = ∛(x - 4) - 3
That is the transformed function. So the correct option is D

What is an arithmetic sequence?An arithmetic sequence can be defined as a series of real and natural numbers in which each term differs from the preceding term by a constant numerical quantity.
How to calculate an arithmetic sequence?Mathematically, the nth term of an arithmetic sequence can be calculated by using this expression:
aₙ = a₁ + (n - 1)d
Where:
d represents the common difference.a₁ represents the first term of an arithmetic sequence.n represents the total number of terms.After the first person cuts off 1/4, the piece of paper left is given by:
Fraction = 1/4 × 80
Fraction = 20
Remainder = 80 - 20 = 60 square inches.
After the second person cuts off 1/4, the piece of paper left is given by:
Fraction = 1/4 × 60
Fraction = 15
Remainder = 60 - 15 = 45 square inches.
After the second person cuts off 1/4, the piece of paper left is given by:
Fraction = 1/4 × 45
Fraction = 11.25
Remainder = 45 - 11.25 = 33.75 square inches.
