+ x−12 and verify the relationship between the zeroes
and the coefficients.
Rewrite the given polynomial in the form ax² + bx + c:
To find the zeros, set the function to zero and solve for x using the quadratic formula.
Quadratic formula:
Therefore,
a = 2√3

c = - 4√3
Substituting the values into the quadratic formula:
The sum of the roots of a polynomial is -b/a:
The sum of the found roots is:
Hence proving the sum of the roots is -b/a
The product of the roots of a polynomial is: c/a
The product of the found roots is:
Hence proving the product of the roots is c/a
Therefore, the relationship between the roots and the coefficients is verified.

You have 4 tests so far and you scored 12, 14, 11, 13. You want to keep your overall average at 12. Write and solve
the equation you would use to find what do you need to score on your fifth test to keep this average.
Answer:
You would need to score a 10.
Set-UpThe equation is going to have a total of 5 values where one is unknown. We will call this unknown x and include it as a value in the equation.
Since we are going to have to find an average, we will need a fraction. We also know we will take five total tests. This will equal 12 as this is the desired average.
To start, create the fraction that will add all five values together and divide that by the number of values.
[tex]\displaystyle \frac{12+14+11+13+x}{5}[/tex]
Then, set this equal to 12.
[tex]\displaystyle \frac{12+14+11+13+x}{5}=12[/tex]
SolveTo solve, we will first combine all like terms.
[tex]\displaystyle \frac{50+x}{5}=12[/tex]
Then, divide the fraction.
[tex]\displaystyle 10+\frac{x}{5}=12[/tex]
Now, move the constants to the right side of the equation. To do this, subtract 10 from 12.
[tex]\displaystyle \frac{x}{5}=2[/tex]
Finally, multiply both sides of the equation by 5 to get rid of the denominator.
[tex]x=10[/tex]
Therefore, on test 5, you must score a 10 to maintain an average of 12.

Ilana says that a fraction with a prime number in the numerator is always in simplest form. Is Ilana correct? Explain.
Answer:
She is correct.
In order to turn a fraction into its simplist form, you need to not be able to divide the numerator or the denominator by ANY integer. A prime number is not divisible by anything, so it is its simplist form.

Explain how you determined the inequality that is represented by the given graph. What was your thought process?
I will mark brainliest .
The inequality that is represented by the given graph is; y > 2x + 1
What is the Inequality of the Graph?From the given graph, we have the following points coordinates;
(x1, y1) = (2, 5)
(x2, y2) = (6, 13)
The formula to calculate the slope is;
m = (y2 - y1)/(x2 - x1)
Thus;
m = (13 - 5)/(6 - 2)
m = 8/4
m = 2
On the graph, we have the following observations:
The line of the graph is a dashed line (this represents > or <)
The upper part is shaded (this represents >)
Thus, the inequality is; y > 2(x - 2) + 5
y > 2x - 4 + 5

Gwendolyn draws a hotdog on graph paper using the scale shown below. The hotdog has a length of 999 units in the drawing. What is the length in c, m, , of the actual hotdog?
The length of the actual hotdog is 15 cm
How to determine the length of the actual hotdog?The graph that completes the question is added as an attachment
The length of the hotdog in the figure is given as
Length = 9 units
The scale is given as
Scale: 6 units = 10 cm
So, we have
6 * 9 units = 10 * 9 cm
Divide both sides by 6
So, we have
9 units = 15 cm
Substitute 9 units = 15 cm in Length = 9 units
Length = 15 cm

What are areas?The area of a shape is the amount of space on the shape.
For most regular shapes, the area is the product of their width and the length
How to determine the expression for the perimeter of the figure?The area of this rectangle is given as
Area = 3m - 7m - 6
Evaluate the like terms
So, we have
Area = -4m - 6
The common factor of 4 and 6 is 2
So, we have the following equation
Area = 2(-2m - 3)
The area of the rectangle is
Area = Length * Width
So, we have
Length, L = 2
Width, W = -2m - 3
The perimeter of the rectangle is calculated as
P = 2 x (L + W)
So, we have
P = 2 x (2 - 2m - 3)
Evaluate the like terms in the above expression
So, we have
P = 2 x (-1 - 2m)
Open the bracket in the above expression
So, we have
P = -2 - 4m

An oceanic -oceanic convergence give rise to volcanic island arcs.
When one oceanic plate subducts another, oceanic-oceanic convergence occurs, leading in the creation of volcanic islands and trenches.Volcanic arcs are volcanoes that originate over a subducting plate and have the shape of an arc. Volcanic activity along a subduction zone, which happens when an oceanic plate falls beneath an oceanic or continental plate, leads to volcanic island arcs.What kind of convergence results in the arcs of volcanic islands?
A volcanic island arc is created when two oceanic plates collide, with the older and heavier of the two subducting beneath the other to start volcanic activity. This process is similar to what happens in an oceanic-continental convergent plate boundary.Learn more about volcanic island arc

Two trains going in opposite directions leave at the same time. train b travels 10 mph faster than train a. in 7 hours the trains are 630 miles apart. find the speed of each.
If two trains going in opposite directions leave at the same time and train b travels 10 mph faster than train a and in 7 hours the trains are 630 miles apart, then the speed of the faster and slower train is equal to 50mph and 40mph respectively.
The speed of each train can be determined by using an algebraic
expression.
As one train travels 10 miles per hour faster than the other, consider x to be the speed of the slower train. In this case, the algebraic expression to find the speeds of each train can be given as,
7x + 7(x + 10) = 630
7x + 7x + 70 = 630
14x = 630 - 70
14x = 560
x = 560 ÷ 14
x = 40 mph
Therefore, x + 10 = 40 mph + 10 mph = 50 mph
Hence, the speed of the faster train is 50 mph and the speed of the slower train is 40mph.

Find BC if B(8, -7) and C(-4,-2).
Solving the Question
We're given:
B(8, -7)C(-4,-2)Find BCWe can use the distance equation to help us solve this question:
[tex]d=\sqrt{(x_2-x_1)^2+(y_2-y_1)^2}[/tex]
[tex](x_1,y_1)[/tex] and [tex](x_2,y_2)[/tex] are the endpoints of the line segmentPlug in the given points:
[tex]d=\sqrt{(x_2-x_1)^2+(y_2-y_1)^2}\\d=\sqrt{(8-(-4))^2+(-7-(-2))^2}\\d=\sqrt{(8+4)^2+(-7+2)^2}\\d=\sqrt{(12)^2+(-5)^2}\\d=\sqrt{144+25}\\d=\sqrt{169}\\d=13[/tex]
AnswerThe length of line segment BC is 13 units.
Using the distance formula, the length of BC is: 13 units.
How to Apply the Distance Formula?Given that:
B(8, -7) = (x1, y1)
C(-4,-2) = (x2, y2)
The distance formula that would be used to find BC is, d =[tex]\sqrt{(x_2 - x_1)^2 + (y_2 - y_1)^2}[/tex].
Thus, applying the distance formula, we have:
BC = √[(−4 − 8)² + (−2 − (−7))²]
BC = √[(−12)² + (5)²]
BC = √(144 + 25)
BC = √169
BC = 13 units
Therefore, using the distance formula, the length of BC is: 13 units.
