Use the vertical line test to determine if the graph is a function or not a function.
Answers
Answer:
Use the vertical line test to determine if the graph is a function or not a function.
On a coordinate plane, a graph decreases to a minimum point, and then increases.
✔ function
On a coordinate plane, a graph increases to a maximum, decreases to a minimum, increases to the maximum, and decreases again to the minimum.
✔ function
On a coordinate plane, a graph decreases to the right, then decreases to the left, then decreases to the right.
✔ not a function
Step-by-step explanation:
As per the concept of the vertical line test, the third graph is not a function.
But the First and Second graphs represent a function.
The vertical line test is a method used to determine if a graph represents a function. It involves visually inspecting the graph and checking if any vertical line intersects the graph at more than one point.
Let's apply the vertical line test to the given graphs:
First graph:
For the first graph, if we draw any vertical line, it will intersect the graph at most once. Hence, the graph passes the vertical line test, indicating that it represents a function.
Second graph:
For the first graph, if we draw any vertical line, it will intersect the graph at most once. Hence, the graph passes the vertical line test, indicating that it represents a function.
Third graph:
The vertical line test is given in the image below.
In conclusion:
The third graph is not a function.

Every 8th person at a concert receives a free t-shirt. Every 10th person receives a free keychain. If there are 160 people who attended the concert how many people will receive both a t-shirt and a keychain?
Answers
Answer:
4 people will receive both a t-shirt and a keychain.
Step-by-step explanation:
To determine how many people will receive both a t-shirt and a keychain,
First we will determine those that will receive a t-shirt and as well determine those that will receive a keychain.
For those that will a receive a t-shirt
Since every 8th person receives a t-shirt, then
The 8th, 16th, 24th, 32nd, 40th, 48th, 56th, 64th, 72nd, 80th, 88th, 96th, 104th, 112th. 120th, 128th, 136th, 144th, 152nd, and 160th persons will receive a t-shirt.
For those that will receive a keychain
Since every 10th person receives a keychain, then
The 10th, 20th, 30th, 40th, 50th, 60th, 70th, 80th, 90th, 100th, 110th, 120th, 130th, 140th, 150th, and 160th persons will receive a keychain.
From above, those that will receive both a t-shirt and a keychain are the 40th, 80th, 120th, and 160th persons.
Hence, 4 people will receive both a t-shirt and a keychain.

Is the relationship linear?
If yes, what is the rate of
change?
Answers
Answer
Linear, [tex]\frac{4}{-3}[/tex] is the slope
Step-by-step explanation:
Its linear because the rate of change doesn't change throughout our points.
Lets use our coordinate points for the bottom and middle one, making 1 our rate of our graph.
The bottom one that's closest to the x-axis would be (8,2). Move 8, the x, to the right, and up 2, the y The middle one of the points would be (5,6). Move 5, the x, to the right, and up 6, the y.
We have our points, now we find the rate of change, also known as slope.
So the equation for slope is m = [tex]\frac{db}{ca}[/tex] and our points together is (8,2)(5,6). Line up the variables with our points. So for example, 8 would be A, 2 would be B, 5 would be C and so on.
Then we have [tex]\frac{6-2}{5-8}[/tex]. Solve it, and we get [tex]\frac{4}{-3}[/tex].

Henry and Irene working together can wash all the windows of their house in 1 h 40 min. Working alone, it takes Henry 2 1 2 h more than Irene to do the job. How long does it take each person working alone to wash all the windows?
Answers
Answer:
Step-by-step explanation:
Henry and Irene working together can wash all the windows of their house in 1 h 40 min. Working alone, it takes Henry 2 1 /2 h more than Irene to do the job. How long does it take each person working alone to wash all the windows?
Let us represent
The number of hours Irene takes to do the job alone =x
1/x=Irene's work rate
The number of hours Henry takes to do the job alone = x + 2.5
1/(x+2.5)=Henry's work rate
1 hr and 40 min
Converting the 40 minutes to hour
60 mins = 1 hour
40 mins = x
x = 40/60
x = 0.6666666667 hour
1 hour 40 minutes = 1.67hours
Irene and Henry working together to do the job
Their work rate working together
sum of individual work rates=work rate when working together
1/x+1/(x+2.5)=1/1.67
LCD:(x)(x+2.5)(1.67)
(x+2.5)(1.67)+(1.67)(x)=(x)(x+2.5)

solve the system by Substitution 4x+4y=-4 y=-7x-7
Answers
Answer: {-1, 0}
Explanation: Since y = -7x - 7, we can replace the y in our first equation with
a -7x - 7 and our first equation now reads 4x + 4(-7x - 7) = -4.
To solve this equation, first distribute the 4 through the parenthses.
So we have 4x - 28x - 28 = -4.
Now simplify the left side to get -24x - 28 = -4.
Adding 28 to both sides, we have -24x = 24.
Dividing both sides by -24, we find that x = -1.
To find y, plug a -1 back into either equation.
So we have y = -7(-1) - 7 or y = 0.
Our final answer is {-1, 0}.

x= -1,
y=0

You and a group of friends participate in a game where you must use clues to escape from a room. You have a limited amount of time to escape and are allowed 3 free clues. Additional clues may be requested, but each removes 5 minutes from your remaining time. What integer represents the total change in the time when you use 5 clues?
Answers
Answer:
The integer that represent the total change in time when 5 clues are used is 10
Step-by-step explanation:
The given parameters are;
The number of free clues available = 3
The number of minutes removed for an additional clue = 5 minutes
Therefore, the total change in time when 5 clues are used is given as follows;
The number of free clues available 3
The number of clues for which 5 minutes is removed from the remaining time when 5 clues are selected = 5 - 3 = 2 clues
Therefore, the total change in time = The number additional clues × 5 minutes/clue
The total change in time = 2 clues × 5 minutes/clue = 10 minutes
The total change in time = 10 minutes
Therefore, the integer that represent the total change in time (in minutes) when 5 clues are used = 10.

If y is directly proportional to x, and y = 56 when x = 6, what is
the value of x when y = 84?
A)6
B)9
C)13
D)15
Answers
Answer:
B) 9
Step-by-step explanation:
According to the statement, we have the following relationship:
[tex]y \propto x[/tex]
[tex]y = k\cdot x[/tex] (Eq. 1)
Where:
[tex]k[/tex] - Proportionality constant, dimensionless.
[tex]x[/tex] - Independent variable, dimensionless.
[tex]y[/tex] - Dependent variable, dimensionless.
Such constant is eliminated by constructing this relationship:
[tex]\frac{y_{2}}{y_{1}} = \frac{x_{2}}{x_{1}}[/tex]
[tex]x_{2} = \left(\frac{y_{2}}{y_{1}} \right)\cdot x_{1}[/tex] (Eq. 2)
If we know that [tex]y_{1} = 56[/tex], [tex]x_{1} = 6[/tex] and [tex]y_{2} = 84[/tex], then the value of [tex]x_{2}[/tex] is:
[tex]x_{2} = \left(\frac{84}{56} \right)\cdot (6)[/tex]
[tex]x_{2} = 9[/tex]
Hence, the correct answer is B.
A road rises 1 m for every 15 m measured along the road. a) What is the angle of inclination of the road to the nearest degree? b) How far does the car travel horizontally when it travels 15 m along the road ? Give the answer to the nearest tenth of a metre.
Answers
Answer:
The answer is below
Step-by-step explanation:
The road increases by a height of 1 m for every 15 m distance. The slope of a line is the ratio of its rise to run. The slope (m) is the tangent of the inclination. Hence:
Slope = rise / run = tanθ
Where θ is the angle of inclination.
a) Given rise = 1 m, run = 15 m
Slope of road (m) = rise / run
m = 1 m/ 15 m
m = 0.0667
slope = tanθ
tanθ = 0.0667
θ = tan⁻¹(0.0667)
θ = 3.81
θ ≈ 4°
b) cosθ = horizontal distance / 15 m
horizontal distance = 15 m × cos 4
Horizontal distance = 14.96
Horizontal distance = 15 m to nearest tenth
