Option A and D are appropriate.
What does the one solution mean?There is just one correct answer to some equations. There is only one value for the variable in these equations that causes the equation to be true. If you solve an equation and the result is a variable equal to a number, the problem has just one solution.
To date,
1) x has just one solution since -5x + 12 = 5x -5
-5x -5x = -5 -12
-10x = -17
x = 1.7
2) -5x+12=-5x-12 -5x + 5x = -12-12
0x (not possible)
3) -5x+12=5x+12 -5x + 5x = +12-12
0x ( not possible)
4) The equation -5x+12=-12x-12
-5x + 12x = -12 -12
7x = -24
x = -24/7, indicating that x has just one solution.

h(x) = −7x² + 10x - 5
Answer: The expression you provided is a quadratic function in the form of H(x) = ax^2 + bx + c, where a = -7, b = 10, and c = -5. The graph of this function is a parabola with the vertex located at x = -b/2a = -10/(-14) = 5/7. The y-coordinate of the vertex can be found by plugging the x-coordinate into the original function, giving us H(5/7) = (-7)(5/7)^2 + 10(5/7) - 5 = -5/7 + 25/7 - 5 = 0. This means that the vertex of the parabola is located at the point (5/7, 0). The general form of the quadratic function is H(x) = -7(x - 5/7)^2.

Some points of a function are plotted as shown. Select all the points that could also be a part of this function. Choose all that apply.
Point (6,2) is part of the function.
What are functions?
In mathematics, a function is a procedure that uniquely connects the value of one variable to the value of another variable (or variables).
Here, we have the plotted points as:
(0,3), (2,7), (3,1), (5,4), (7,6)
Assuming from the above, we get a sinusoid graph as below.
Now if we try to plot the provided points, we see that only (6,2) satisfies the curve.
Hence, (6,2) is a point that is part of the function.

Cuties and naval oranges are interchangeable, therefore when Cuties' price drops, more mandarin oranges will be consumed by consumers, increasing the demand for naval oranges .
As the Mandarin oranges are an alternative for navel oranges, a decrease in the price of Mandarin oranges will result in more people purchasing Mandarin oranges.
The Federal Water Pollution Control Act Amendments of 1972 were passed in response to growing public knowledge of and concern over water pollution (33 U.S.C. 1251 et seq.).
This law was modified in 1977 (P.L. 95-217), and as a result, it became known as the Clean Water Act (CWA).

If 4/4 = full price,
subtract 3/4
4/4 - 3/4 = 1/4 = 25% of the original price
25% = $1

If m is the centroid of triangle abc, am = 44, ce =54, and dm = 23, find each missing measure. fm=?
If m is the centroid of triangle abc, am = 44, ce =54, and dm = 23, then each missing measure fm=88 and ce=44.
What is the centroid ?The center of the thing is represented by its centroid. The centroid of a triangle is the location where the triangle's three medians intersect. It can alternatively be described as the location where the three medians come together. A line connecting a side's midpoint and the triangle's opposite vertex is called the median.
How do you find the centroid of a triangle with 3 points?Step 1: Identify each vertex's coordinates.
Step 2: Add together and divide by three all the x values from the coordinates of the three vertices.
Step 3: Add together all the y values from the three vertices and divide the result by three.
Step 4: The centroid coordinate is determined from the values collected in stages 2 and 3.
the ratio of both segments is 2:1.
where;
am = 44 and dm = 23
the longer segment is double of shorter one:
2*23 = 46.
Therefore,
fm = 46-23
= <<23=23>>23
now finding ce:
= 2*44
= 88, so
ce measures
= 88-44
=44.

A = -x² + 20 is a quadratic function in standard form that depicts each area as a function of width.
What makes anything a quadratic function?A quadratic in mathematics is a particular kind of problem that involves squaring, or multiplying a variable by itself. This terminology comes from the fact that a square's area equals the product of its side length and itself. Quadratum, the Greek word meaning square, is where the word "quadratic" originates.
Briefing:Now, give the x and y labels to the two sides.
We are aware that a rectangle's area is;
A = length * width
Thus;
A = xy
Given that she has 40 feet of fencing, the following follows:
y = 0.5(40) - x
y = 20 - x
Consequently, the area in the quadratic function formula is;
A = x(20 - x)
A = 20x - x²
A = -x² + 20

A room has the floor dimensions of 50 meters by 60 meters. The height of the basement is 10 meters. What is the total area of all four walls?
Hello,
I hope you and your family are doing well!
To find the total area of all four walls of the room, you need to find the area of each wall separately and then add them all together. The area of a wall is the product of its height and width.
The width of each wall is 50 meters, and the height of each wall is 10 meters, so the area of each wall is 50 * 10 = 500 square meters. There are four walls in the room, so the total area of all four walls is 500 * 4 = 2000 square meters.

Step-by-step explanation: I looked it up
if you were to guess how probability of tunneling through a finite barrier scales with barrier size (once it's bigger than a wavelength), which would you pick?
As an object's mass and the energy difference between it and the barrier's energy increase, the probability that it will tunnel through the barrier diminishes.
And although while the functionality shows that the wave function never fully hits zero, this explains why tunneling is common at the nanoscale but insignificant at the larger scale. The probability of tunneling declines exponentially with the square root of the mass of the particle (smaller particles may more easily tunnel through barriers than larger ones) and the barrier thickness.
Three requirements must be satisfied for a quantum particle to appreciably tunnel through a barrier ,
The barrier's height must be limited and its thickness should be minimal.The barrier's potential energy (E/V) is greater than the particle's kinetic energy.The fact that the wavefunction can pass through the barrier indicates that the particle possesses wave characteristics. This shows that quantum tunneling does not apply to macroscopic items and only applies to microscopic objects like protons or electrons.To learn more about tunnelling

what does the univariate t test tell you that the bivariate correlation test alone does not? what does the bivariate test tell you that the univariate test does not tell you?
In univariate data, only one variable is assessed for each person. Two variables are measured for each person in bivariate data.
The definition of univariable data is "one variable," and it is generally understood to be one sort of data. It is one of the straightforward methods for data analysis. The data in univariable data only include one variable.
The cat's weight, for instance, is 10, 15, 25, 27, 30, 35, and 40.
The variable is hence "Cat weight."
The definition of bivariate data is "Two Variable," and it essentially consists of two different forms of data. It is a straightforward type of statistical analysis.
Only one variable is analysed at a time in univariate statistics. Two variables are compared in bivariate statistics. Multiple variables are compared using multivariate statistics.
In a bivariate analysis, the correlations between the two variables are measured. When there are more than two variables in the data set, a more complicated statistical analysis technique called multivariate analysis is utilized.
Therefore,
In univariate data, only one variable is assessed for each person. Two variables are measured for each person in bivariate data.
