8th/9th-95 POINTS+BRAINLIEST!!!!!!!! How do you write a quadratic equation in vertex form? Please explain the steps in simple language and use y=x²+6x+16 as an example.
Answer:
In vertex form: y = 1(x - (-3))² + 7
Vertex: Minimum (-3, 7)
Explanation:
Vertex form: y = a(x - h)² + k
Completing square (rules) :
1st rule: (x + d)² = x² + 2dx + d² and (x - d)² = x² - 2dx + d²
2nd rule: x² + 2dx = (x + d)² - d² and x² - 2dx = (x - d)² - d²
Given equation:
y = x² + 6x + 16
y = x² + 2(3)x + 3² + 7
y = (x + 3)² + 7
Into vertex form:
y = 1(x - (-3))² + 7
From this identify:
a = 1, h = -3, k = 7
Solution, vertex of this equation: Minimum (-3, 7)
Point A, located at (5, -4) is reflected in the y-axis, resulting in the location of point A'. Which of the following statements is true?
Point A' is located at (-5,-4)
Point A' is located at (-5,4)
Point A is located at (4,5)
Point A' is located at (-4,5)
The correct answer is Point A' is located at (-5, -4).
When a point is reflected in the y-axis, its x-coordinate is negated and its y-coordinate remains the same. Therefore, the x-coordinate of point A changes from +5 to -5, and the y-coordinate remains -4. Hence, the coordinates of A' are (-5, -4).

Answer:
\(\frac{16}{27}\)
Step-by-step explanation:
From the table, we notice that the total number of students is:
\(3+10+8+6=27\)
Then, along the second column of the table, we notice that the number of students who do not have a brother is:
\(10+6=16\)
So, the probability that a randomly chosen student does not have a brother is:
\(\frac{\text{number of students who do not have a brother}}{\text{total number of students}}=\frac{16}{27}\)

A submarine submerges from the surface of the sea at the rate of 10 m/min. How long will it take to reach 300 m below the sea level
Answer:
answer is 300m/30min
Step-by-step explanation:
300\10=30
Given the speed of the submarine, the total time it will take to cover the the given distance is 30 minutes.
How long will it take the submarine to reach 300 m below the sea level?Using the expression Time = distance / speed.
Given that;
Speed = 10m/minDistance = 300mTime = ?Time = distance / speed
Time = 300m / 10m/min
Time = 30 minutes
Given the speed of the submarine, the total time it will take to cover the the given distance is 30 minutes.

What is the decimal expansion for 12
2
3?
A.12.6
B.12.65
C.12.6
D.12.66
pls help me
Answer:
D is the right choice and no you cannot fit the pizza inside the box.
Step-by-step explanation:
D is the answer because to turn 2/3 into a decimal you would divide 2 by 3 and the answer you would get would be 0.66666666666...You would then add 12 to the answer and get 12.6666... Once you get this answer you would round it to the hundredths to get 12.67 but since that is not an option you could use D, 12.66 inches.
Answer:
I believe the answer is D.

Polygon JKLM is drawn with vertices J(−4, −3), K(−4, −6), L(−1, −6), M(−1, −3). Determine the image coordinates of L′ if the pre-image is reflected across y = −3.
L′(−3, 6)
L′(−1, 6)
L′(−1, 0)
L′(1, 0)
To reflect the pre-image across y = -3, we need to flip the entire polygon over the line y = -3. This means that the x-coordinates of each point will remain the same, but the y-coordinates will be reflected across the line.The y-coordinate of point L is -6, which is 3 units below the line y = -3. When reflected, this point will be 3 units above the line y = -3. Therefore, the image coordinates of L' will be (−1, 0), since the x-coordinate of L is -1 and the y-coordinate of L' is 3 units above y = -3, which is 0.So, the image coordinates of L' are (−1, 0).
Rewrite the expression 12x + 8 to find an
equivalent expression. Show three possible
expressions. What do the rewritten expressions
tell you about the relationships among the
quantities?
Answer:
12(x + 8) 8(x + 12) and x( 12 + 8) all equal to 20x
Step-by-step explanation:
Three equivalent expressions of 12x + 8 are, 2(6x + 4), 4(3x + 2) and
8 + 12x.
What are GCF and distributive property?The GCF of two or more than two numbers is the highest number that divides the given two numbers completely.
We also know that distributive property states a(b + c) = ab + ac.
Given, An expression 12x + 8.
Now, The first way of writing an equivalent expression to 12x + 8 is,
2(6x + 4).
The second one is,
4(3x + 2).
We can also write an equivalent expression for 12x + 8 by the commutative law of addition (a + b) = (b + a).
Therefore, 12x + 8 is equivalent to 8 = 12x.

You select a marble without looking and then put it back. If you do this 32,000 times, what is the best prediction possible for the number of times you will pick an orange marble?
LOOK AT THE IMAGE QUICKLYYY
Answer:
12,000 times
Step-by-step explanation:
The probability of selecting an orange marble in each individual selection is given by:
P(Orange) = Number of orange marbles / Total number of marbles
P(Orange) = 3 / 8 = 0.375
To determine the best prediction for the number of times you will pick an orange marble, we can multiply the probability of selecting an orange marble by the total number of selections:
Best prediction for the number of times you will pick an orange marble = P(Orange) * Total number of selections
Best prediction for the number of times you will pick an orange marble = 0.375 * 32,000
Best prediction for the number of times you will pick an orange marble = 12,000
Therefore, the corrected best prediction possible for the number of times you will pick an orange marble is also 12,000.

please write a function for the points (1/3,0) (-2 3/4,0) and (0,-5) and explain the steps.
thank you!
The function for the points are y = -15x - 5
How to determine the functionFrom the information given, we have that;
The points are;
(1/3,0) (-2 3/4,0) and (0,-5)
Using the point-slope form of a linear equation, we have;
y - y₁ = m(x - x₁)
Such that;
m is the slope of the liney - y₁ and (x - x₁) are the pointsUsing (1/3, 0) and (0, -5), we have that the slope is;
m = (0 - (-5))/0 -1/3)
expand the bracket
= 5 / (-1/3)
= -15
Now, take any of the given points and substitute the values
Using (1/3, 0), we get;
y - 0 = -15(x - 1/3).
y = -15x - 5.

The function for the points solved by (1/3,0) (-2 3/4,0) and (0,-5) solved by point slope form is \(a=-15b-5\)
We have given the points:
(1/3,0) (-2 3/4,0) and (0,-5)
Using the formula of linear equation
\(a-\)\(a_{1}\)\(=x[b-b_{1}]\)
Where we will consider (1/3,0) = \(a-a_{1}\) and (0,-5) = \(b-b_{1}\)
that is 1/3 = \(a\), 0 = \(a_{1}\) and
0 = \(b\), -5 = \(b_{1}\)
\(x\) refers to the slope of line (take any variable)
Now for finding the value of \(x\),
\(x=a-a_{1}/b-b_{1}\)
inserting the values,
\(x=[0-[-5]]/[0-1/3]\\x= -15\)
Substitute the value of \(x\) in the equation
\(a-0=-15[b-1/3]\)
By simplifying the equation, we get
\(a=-15b-5\)

Answer:
5: x=11 and supplementary
7: The angle measure to the left is 107, the angle measure to the right is 73 (I could not see the letters all that well)
Step-by-step explanation:
We can use supplementary angles to solve for 5 because they both share the same side and one side is equal to 180 degrees
(7x-8)+(13x-32)=180
20x-40=180
20x=220
x=11
First we use supplementary angles to find out the values of x. We set the two angle measures equal to 180 and solve for x. With that done, we can substitute the actual value of x for the x in each angle measure and solve.
(14x-47)+(8x-15)=180
22x-62=180
22x=242
x=11
14(11)-47= 107 [this is the measure of the left angle]
8(11)-15=73 [this is the measure of the right angle]
