Yes, it is possible to draw a plane that includes a line and a third point not on the line. In mathematics, a plane can be defined by three points. Therefore, the two points on the line and the third point not on the line can be used to define the plane.
Explanation:Yes, it is indeed possible to draw a plane that includes a line and a third point not on the line. The definition of a plane in mathematics is that it's a two-dimensional surface that extends infinitely along its length and width, which can be defined by three points. Considering you have two points on the line, and a third point that's not on the line, you could use these three points to define your plane. It doesn't matter whether the three points are collinear or not, the plane can still be defined. The key is that you need at least three non-collinear points to define a plane.

Two more than 4 times a number is -18
Write a quadratic equation having the given solutions -8
Answer:
[tex]y=x^2+16x+64[/tex]
Step-by-step explanation:
A quadratic needs 2 solutions, but since you only have 1, I am to assume that x = -8 twice (or multiplicity of 2). If x = -8, then in factor form, it's (x + 8). Muliplying that by itself twice:
(x + 8)(x + 8):
[tex]x^2+8x+8x+64=0[/tex]
Simplifying gives you:
[tex]x^2+16x+64=y[/tex]

Harvey collects rare marbles. He has 112 marbles in his collection. If he uses Seven Trees to hold all of the marbles, how many marbles will he display on three trays? Is tray hold an equal number of marbles answers at brainly.com
Final answer:
Harvey has 112 marbles distributed equally across seven trays. Each tray holds 16 marbles, therefore, on three trays, Harvey will display a total of 48 marbles.
Explanation:
Harvey has 112 marbles in his collection and uses seven trays to hold all of the marbles. To find out how many marbles Harvey will display on three trays, we need to divide the total number of marbles by the total number of trays to find out how many marbles each tray holds.
First, divide 112 marbles by 7 trays to find out how many marbles go on each tray. The calculation is as follows:
112 marbles ÷ 7 trays = 16 marbles per tray
Now that we know each tray holds 16 marbles, to find out how many marbles are displayed on three trays, we multiple the number of marbles per tray by the number of trays:
16 marbles per tray × 3 trays = 48 marbles
Therefore, Harvey will display 48 marbles on three trays.
Bella's score on a spelling test is a function of the number of hours she studies. Which expression represents Bella's score on a spelling test if she studies for 3 hours?
A. 3(score)
B. Score(3)
C. Score + 3
D. 3 - score
Answer:
B. Score(3)
Step-by-step explanation:
Given,
Bella's score on a spelling test is a function of the number of hours she studies.
Let x represents the number of hours and S represents her score after x hours,
Thus, her scoring after x hours = S( x )
If she studies for 3 hours,
That is, x = 3,
Then her score would be S(3) or we can say that score(3).
Hence, option 'B' is correct.

Suppose you start with at least $82 in your savings account and deposit $32 each week. Write, solve, and graph an inequality to describe how much money, m, you have after 10 weeks, w.
Answer:
m ≥ 82 + 32w
m ≥ 402
Step-by-step explanation:
Here, w represents the number of weeks and m represents the total amount in the account after w weeks,
The amount of money saved in each week = $ 32,
So, the total amount saved after weeks = 32w dollars,
Since, the original amount in the account = $ 82
The total amount in the account = 82 + 32w
Thus, the required inequality would be,
m ≥ 82 + 32w
If w = 10,
The amount in the account after 10 weeks = 82 + 32(10) = 82 + 320 = $ 402
⇒ m ≥ 402
That is, the closed circle on 402 and shaded right in the number line ( shown below )

What is a Quadratic Equation?A quadratic equation is what can be written in the form of ax²+bx+c=0
The equation is,
2x² + x − 4 = 0
To solve the equation, the equation needs to be factorized.
It can be also solved using the formula for determining roots.
x = ( -b ± √ (b² -4ac)) / 2a
Comparing it with the standard equation ax²+bx+c=0.
a = 2, b = 1, c = -4
Substituting the values
x = ( -1 ± √ (1² -4*2*-4)) / 2 * 2
x = ( -1 ± √ (1 + 32)) / 2 * 2
x = ( -1 ± √33 ) / 2
The solution of the given quadratic equation is x = ( -1 ± √33 ) / 2.

Total money = 9 + 10 + 13 + 13 = $45
Total number of persons = 4
For the first $1 there are 8 token
And after that cost of 4 tokens is $1,
Total tokens = 8×1 + 4×(45 - 1)
Total tokens = 8 + 176

If it takes about 20 minutes to grade a student paper how long in hours does it take to grade palers for a class of 25 people
Final answer:
It takes about 20 minutes to grade one student's paper, so for a class of 25 students, it would take a total of 500 minutes, which is approximately 8.33 hours to grade all the papers.
Explanation:
If it takes about 20 minutes to grade a student paper, to find out how long it takes to grade papers for a class of 25 students, we need to multiply the number of students by the time taken to grade each paper.
Step-by-Step Calculation:
Multiply the number of students (25) by the minutes per paper (20 minutes): 25 students * 20 minutes per student = 500 minutes.
Convert minutes to hours. Since there are 60 minutes in an hour, we'll divide the total minutes by 60: 500 minutes ÷ 60 minutes per hour = 8.33 hours.
Therefore, it takes approximately 8.33 hours to grade papers for a class of 25 students. Please note that this is an ideal situation without any breaks or interruptions accounted for.
