The correct option 3. D is C reflected across the y-axis; only the signs of the x-coordinates are different for C and D.
Explain the meaning of reflection of the coordinates?A figure is transformed into a reflection by a transformational process. In a point, linear line, or a plane, figures can be reflected. The image and preimage coincide when reflecting a graphic in a line or a point.The locations of C and D's coordinates are supplied to us as follows:
Point C is 1.5 units towards the left as well as 3 units up from the origin.x = -1.5 units away from the origin. Origin is at 1.5 and 3 up, or y = 3.As a result, C is the first coordinate just on axis (-1.5, 3).
Point D is 1.5 units toward the right as well as 3 units up from the origin.X is equal to 1.5 units to the origin's right, while Y is equal to 3 units to the origin.As a result, D is the second coordinate upon that axis (1.5, 3).
We can observe that the sign of the x-coordinates for C and D is opposite.It would be a reflection over the y-axis if the sign of the x coordinates were opposite.Thus, the statement D is C mirrored across the y-axis, with the only difference between C and D being the sign of the x-coordinates, best captures the relationship between the locations of the 2 midfield players.

What is a parabola?An equation of a curve that has a point on it that is equally spaced from a fixed point and a fixed line is referred to as a parabola. The parabola's fixed line and fixed point are together referred to as the directrix and focus, respectively. It's also crucial to remember that the fixed point is not located on the fixed line. A parabola is a locus of any point that is equally distant from a given point (focus) and a certain line (directrix). An essential curve of the coordinate geometry's conic sections is the parabola.

A salesman is carrying a big bag for selling a machine. In addition to the machine that the salesman wants to sell, there is some personal stuff. The weight of his machine is three kilogram and half a machine. In addition to the machine, there is a repair tool for the machine that weighs half kilogram and one-fourth of the machine. The personal stuff weighs four kilogram minus a fourth of the weight of the machine. Finally, the salesman has some supplies that weigh two-fifth of the machine and personal stuff combined. What is the total weight in the bag of salesman
The total weight of the bag that the salesman is carrying for selling a machine including some personal stuff is 13.9 Kg.
What is a fraction?A fraction is a rational number that consists of a numerator and a denominator, used to represent a part of the whole thing.
Calculation:It is given that,
A salesman is carrying a big bag for selling a machine.
Consider the weight of the machine = w
So,
The weight of his machine is three kilograms and half a machine. I.e.,
w = 3kg +w/2
⇒ w/2 = 3kg
∴ w = 6kg
Thus, the weight of the machine is 6 Kg.
So, the weight of the repair tool for the machine = a half kilogram and one-fourth of the machine
⇒ 1/2Kg + 1/4w
⇒ 1/2 + 6/4
⇒ 2 Kg
The personal stuff weighs - four kilograms minus a fourth of the weight of the machine.
⇒ 4Kg - w/4
⇒ 4 - 6/4
⇒ 2.5 Kg
He has some supplies that weigh two-fifth of the machine and personal stuff combined.
⇒ 2/5(w + 2.5)
⇒ 2/5 × 8.5
⇒ 3.4 Kg
Thus, the total weight of the bag = 6 Kg + 2 Kg + 2.5 Kg + 3.4Kg = 13.9Kg.
Therefore, the total weight of the salesman's bag is 13.9 Kg.

B. f(x) is an even function so both ends of the graph go in the same
direction.
C. The leading coefficient is positive so the left end of the graph
goes up.
D. f(x) is an even function so both ends of the graph go in opposite
directions.
The end behavior of the Polynomial f(x) = -4x⁶ + 6x² - 52 is;
B. f(x) is an even function so both ends of the graph go in the same
direction
The end behavior of a polynomial function is the behavior of the graph of f(x) as x approaches positive infinity or negative infinity.
Now, we are given the polynomial;
f(x) = -4x⁶ + 6x² - 52
Let us first test if the polynomial is even;
f(1) = -4(1)⁶ + 6(1)² - 52
f(1) = -50
Similarly;
f(-1) = -4(-1)⁶ + 6(-1)² - 52
f(-1) = -50
Since f(1) = f(-1), we can say that both ends of the graph go in opposite
directions.
Lastly, the leading coefficient is negative because it is -4 and as such it means that the left end goes down.

There were only 86 confirmed cases of Measles in the year 2000. In 2019, there was a reported 1,350 % increase in confirmed
cases of Measles. How many cases were there in 2019?
Answer:
1161 confirmed cases
Step-by-step explanation:
In 2000 the number of cases was 86
Percent means out of a hundred, so if we divide 1350 by 100 we get 13.5.
So, we must multiply 13.5 and 86 to get the amount of cases in 2019.
13.5*86 = 1161 confirmed cases in 2019
Question down below about linear equations.
The system of equations is -x + y = 4 and -2x + y = 0
How to create the system of linear equations?To do this, we make use of the following ordered pairs
(4, 8)
The above point represents April 2008.
Let the system of equations be
mx + ny = 4
2mx + ny = 0
Substitute (4, 8) for x and y in the above equations.
4m + 8n = 4
8m + 8n = 0
Subtract both equations
4m - 8m = 4
This gives
-4m = 4
Divide by 4
m = -1
Substitute m = -1 in 8m + 8n = 0
-8 + 8n = 0
This gives
8n = 8
Divide by 8
n = 1
So, the system of equations is -x + y = 4 and -2x + y = 0
The graph of the system of equationsThe system of equations is -x + y = 4 and -2x + y = 0
See attachment for the graph of the system
Prove that the solution is (4, 8)The above is represented in the (a) part of this solution
Verify that the solution is (4, 8)We have:
-x + y = 4 and -2x + y = 0
Substitute (4, 8) for x and y in the above equations.

Hello!
25° and x° are vertical angles, therefore they are equal to each other.
Vertical angles are angles formed by two intersecting lines that are non-adjacent.
The angle to the right of 80° would be 55°, because the sum of angles on a line is 180°.
Angle x would be 25° because the other straight line contains angles 80°, 50° and x°.
