What is a graph?A graph is the representation of the data on the vertical and horizontal coordinates so we can see the trend of the data. In discrete mathematics, and more specifically in graph theory.
A graph is a structure consisting of a set of objects, some of which are "related" in some way. The objects correspond to mathematical abstractions known as vertices, and each pair of related vertices is known as an edge.
1. The graph in option 1 is Neither. It is not discrete and continuous.
2. The graph in option 2 is discrete. The values of the data are not in a specific pattern.
3. The graph in option 3 is discrete. The values of the data are not in a specific pattern.
4. The graph in option 4 is continuous. The points in the graph are varying continuously.

Stephanie and Jose both want to buy a skateboard. Stephanie has already saved $25 and plans to save $5 a week until she can buy the skateboard. Jose has $16 and plans to save $8 a week. How many weeks will it take for them to have the same amount of money and how much will they have?
(Also if u can pls type out ur answer like "10 weeks and $100" hehe)
Answer: 3 weeks and $40
Step-by-step explanation:
Let the number or weeks taken for them to have same amount be represented by x.
The information given in the question can be presented as an equation as:
Stephanie = 25 + 5x
Jose = 16 + 8x
We then equate them together
25 + 5x = 16 + 8x
25 - 16 = 8x - 5x
3x = 9
x = 9/3 = 3
The number of weeks is 3
The amount of money that they'll have will be:
= 25 + 5x
= 25 + 5(3)
= 25 + 15 = $40

Tony has $300 in his bank account. He takes out $10 each week for "W" weeks. After "W" weeks he has "D" dollars left in his bank account. Write an equation that represents the amount of money left in his bank account after "W" weeks.
Answer:
The Equation :
D = 300 - 10W
Step-by-step explanation:
We are told in the above question that:
Tony has $300 in his bank account. He takes out $10 each week for "W" weeks.
Where W = number of weeks
Our Equation is written as
Total amount in the bank account - $10 × W
= $300 - $10 × W
The Equation is given as
D = 300 - 10W

In equilateral triangles STU:
==========================================================
Explanation:
Equilateral triangles have three equal sides, ie the sides are all the same length.
Let's set sides ST and TU equal to each other and solve for x
7x-10 = 2x+25
7x-2x = 25+10
5x = 35
x = 35/5
x = 7
Then we use this to compute each side
ST = 7x-10 = 7*7-10 = 49-10 = 39TU = 2x+25 = 2*7+25 = 14+25 = 39US = x^2 - 10 = 7^2 - 10 = 49-10 = 39Each side is 39 units long, so this confirms we have the correct answer.

Use the midpoint formula to estimate the sales of Cars, Inc. in 2009, given the sales in 2008 and 2010. Assume that the sales of Cars, Inc. sales always follow a linear pattern. (Round to nearest whole number) Year Sales (in millions) 2008 240 2010 280 millions Enter the answer
Answer:
The estimated sales were $260 million
Step-by-step explanation:
Assume the endpoints of a segment are (x1,y1) and (x2,y2).
The midpoint (xm,ym) is calculated as follows:
[tex]\displaystyle x_m=\frac{x_1+x_2}{2}[/tex]
[tex]\displaystyle y_m=\frac{y_1+y_2}{2}[/tex]
The sales ov Cars, Inc. were (2008,240 million) and (2010,280 million). We need to use the midpoint to estimate the sales in 2009:
[tex]\displaystyle x_m=\frac{2008+2010}{2}=2009[/tex]
[tex]\displaystyle y_m=\frac{240+280}{2}=260[/tex]
The estimated sales were $260 million

Juan thinks that the graph of 6y + 12x = 4 is a line. a. Solve Juan’s equation for y.
The equation of the line in the slope-intercept form will be y = 2/3 - 2x.
What is a linear equation?A connection between a number of variables results in a linear model when a graph is displayed. The variable will have a degree of one.
The linear equation is given as,
y = mx + c
Where m is the slope of the line and c is the y-intercept of the line.
Juan thinks that the graph of 6y + 12x = 4 is a line.
Solve the equation of the line for y, then we have
6y + 12x = 4
6y = 4 - 12x
y = 4/6 - (12/6)x
y = 2/3 - 2x
The equation of the line in the slope-intercept form will be y = 2/3 - 2x.

During the last schools football game, the Home Team scored 13 more points than the Visiting
denm. The total of their scores was 47. How many points did each team score?
Answer:
Home 30, visitor 17.
Step-by-step explanation:
Visiting team score is x. Home score is then x+13. Total of both is 47 so...
x+(x+13)=47
2x+13=47
2x-34
x=17
x+13=30
The score of Home Team is 30 points.
The score of Visiting team is 17 points.
Here,
During the last schools football game, the Home Team scored 13 more points than the Visiting team.
The total of their scores was 47.
We have to find points of each team score.
What is Number system?
A number system is a system representing numbers. It is also called the system of numeration.
Now,
Let Visiting team score x points.
Then, Home team score is 13 more points than the Visiting team.
Home team score x + 13 points.
The total of their scores was 47.
Hence,
x + (x + 13) = 47
2x + 13 = 47
2x = 47 - 13
2x = 34
x = 17
So, The score of Visiting team is 17 points.
And, The score of Home Team = 17 + 13 = 30 points.

Step-by-step explanation:
Kira ,Charlie , and Miguel have a total of $105 in their wallets . Kira has $9 less than Miguel. Charlie has 4 times what Miguel has . How much does each have ?
Let the money with Miguel be x.
Then :
Money with Kira = x - 9
Money with Charlie = 4x
Total money in their wallet = $105
This can be written in an equation as :
[tex] = \tt \: x + x - 9 + 4x = 105[/tex]
[tex] = \tt2x + 4x - 9 = 105[/tex]
[tex] = \tt 6x - 9 = 105[/tex]
[tex] = \tt6x = 105 + 9[/tex]
[tex] = \tt6x = 114[/tex]
[tex] = \tt x = \frac{114}{6} [/tex]
[tex] = \tt x = 19[/tex]
Which means :
Money with Miguel = $19
Money with Kira :
= 19 - 9
Thus, Kira has $10 in her wallet.
Money with Charlie :
= 4 × 19
= 76
Thus, Charlie has $76 in his wallet.
Therefore, Money with Kira = $10Money with Charlie = $76Money with Miguel = $19Answer:
Let the money with Miguel be x.
Then :
Money with Kira = x - 9
Money with Charlie = 4x
Total money in their wallet = $105
This can be written in an equation as :
= \tt \: x + x - 9 + 4x = 105=x+x−9+4x=105
= \tt2x + 4x - 9 = 105=2x+4x−9=105
= \tt 6x - 9 = 105=6x−9=105
= \tt6x = 105 + 9=6x=105+9
= \tt6x = 114=6x=114
= \tt x = \frac{114}{6}=x=

114
= \tt x = 19=x=19
Which means :
Money with Miguel = $19
Money with Kira :
= 19 - 9
Thus, Kira has $10 in her wallet.
Money with Charlie :
