What is a Quadratic equation and its solution?A quadratic equation in the variable x is an polynomial of degree 2 equation of the form ax²+bx+c = 0 where a, b, c are real numbers a≠0. For example, 2x²-3x+1 =0. And we say that x=α is an solution of a quadratic equation if α satisfies the equation and since its degree is two it will always have 2 solutions which may be real or Imaginary.
Given equation here is : x² -8x+16= 0
x²-2.4x+4²=0
(x-4)²=0
x=4,4
Hence, the quadratic equation has two equal and real solutions.

y-axis.
Answers
Answer:
A line parallel to the y-axis has no defined slope, and a line parallel to the x-axis has slope of zero.
Step-by-step explanation:
Lines parallel to the y-axis are vertical and are undefined as they don't technically have a gradient.
lines parallel to the x-axis are horizontal and have a gradient of 0 since there is no positive or negative angle, it's just straight.

The coordinates of the endpoints of the diameter of a circle are (3,7) and (-5,3). Find the coordinates of the center of the circle
Answers
Answer:
[tex](-1,5)[/tex]
Step-by-step explanation:
The definition of the diameter indicates it passes through the center of the circle to be called diameter. Therefore finding the midpoint of the line that is the diameter we will find the center of the circle.
To find the coordinates of this midpoint we must make an average of the 'x' values of the two given points, and also an average of the two given 'y' values.
the coordines of this midpoint will be [tex](x_{m},y_{m})[/tex] where [tex]x_{m}[/tex] is the average of the 'x' values, and [tex]y_{m}[/tex] is the average of the 'y' values
The points we have are:
[tex](3,7)[/tex]
where I will call the coordinates: [tex]x_{1}=3[/tex] and [tex]y_{1}=7[/tex]
[tex](-5,3)[/tex]
where I will call the coordinates: [tex]x_{2}=-5[/tex] and [tex]y_{2}=3[/tex]
the average of the 'x' values is:
[tex]x_{m}=\frac{x_{1}+x_{2}}{2}[/tex]
substituting the values:
[tex]x_{m}=\frac{3+(-5)}{2}\\ \\x_{m}=\frac{3-5}{2}\\ \\x_{m}=\frac{-2}{2}\\ \\x_{m}=-1[/tex]
the average of the 'y' values is:
[tex]y_{m}=\frac{y_{1}+y_{2}}{2}\\[/tex]
substituting the values:
[tex]y_{m}=\frac{7+3}{2}\\ \\y_{m}=\frac{10}{2}\\ \\y_{m}=5[/tex]
and the center of the circle (the midpoint of the diameter) is at:
[tex](x_{m},y_{m})[/tex]
which is
[tex](-1,5)[/tex]

Answers
Answer:
A 2-column table has 3 rows. The first column is labeled x with entries 40, 160, 200. The second column is labeled y with entries 60, 15, 0.
Step-by-step explanation:
All of the tables have x=40 in the first column. The function value there is ...
f(x) = (-3/8)(40) +75 = -15 +75 = 60
Only the last table has y = 60 for x = 40.

Silver has a density of 0.04 lb/cm^3. A standard silver bar has a volume of 642
cm^3. To the nearest pound, how much does 1 standard silver bar weigh?
Answers
Answer:
The weight of the mentioned silver bar is:
25.68 LbStep-by-step explanation:
Remember that the formula of density is:
Density = mass / volume.From this formula, you can clear the mass (because this is the valor you need to solve the exercise), so you will have:
Mass = density * volumeWith this last formula, you must replace the values given in the exercise:
Mass = density * volume Mass = 0.04 lb/cm^3 * 642 cm^3 Mass = 25.68 LbYou can check this value using the original formula of density and see if the density has the same valor of the exercise:
Density = mass / volume. Density = 25.68 Lb / 642 cm^3 Density = 0.04 Lb / cm^3Write all of the complex numbers that are graphed

Given that ZBCD and ZBCA form a straight angle, if ZABC measures 55
degrees and ZBCD measures 60 degrees, then the measure of ZBAC is
degrees.
Answers
Answer:
Angle BAC is 5 degrees.
Step-by-step explanation:
It's easiest if you just annotate you diagram as you find each angle. You can do this in lots of different ways, but this is how i got there.
So to find BAC, you need to find ABC and BCA. After you find these two, its just a matter of subtraction, which is simple.
We already know ABC = 55 degrees.
So now we have to find BCA:
1) They told us that BCD is 60 degrees and that its sitting on a straight line
2) From this we can find that BCA is 120 degrees, because a straight line is 180 degrees. 180 -60 = 120 degrees.
Now that we have both ABC and BCA, we can find BAC:
1) The angles of all triangles add up to 180 (idk why, its just how it is)
2) So, if we do 180 - BCA - ABC, we should get BAC
3) So, 180 - 55 - 120 = 5 degrees

Answers
Answer:
Step-by-step explanation:
Let yesterday's price be x
Discount percentage = 36%
Sale price = $ 560
(100-36)% of x = 560
64 % *x = 560
[tex]\frac{64}{100}*x=560\\\\x=560*\frac{100}{64}\\\\x=875[/tex]

Answer:
B)Division
Step-by-step explanation:

divide both side by 3 gives you

When dividing the 3x=9 you need to leave x on its own therefore you decide 3x by 3 to cancel out the multiplication. Than what you do to one side you do to the other so 9/3 = 3 leaving the equation answer: x=3
