Answer:
If x is greater than 0, then y is greater than x
For example:
x = 2 => y = 4(2) = 8, 8 > 2
x = 3 => y = 4(3) = 12, 12 > 3
If x is = 0, then y is equal to x, because x = 0 => y = 4x = 4(0) = 0 => x = y = 0
If x is less than 0, then y is smaller than x
For example:
x = -2 => y = 4(-2) = -8, -8 < -2
x = -3 => y = 4(-3) = -12, -12 < -3

19-3 will be greater
We are multiplying 1/2 *(19-3) which is multiplying by a number less than 1 it will be less than 1
18-3 = 16
1/2 * (19-3)
Using PEMDAS
We do parentheses first

Circumference of a circle
The path or the boundary that encircles any shape is defined by its circumference. In other words, the perimeter is another name for the circumference, which makes it easier to determine how long a shape's outline is. The circle's perimeter is measured in this way. whereas the circumference of a circle determines the space it occupies. The circumference of a circle is its length when it is opened up and drawn as a straight line. Units like cm or unit m are typically used to measure it.
We take radius of the circle and pi to calculate the circumference of circle.
The formula of circumference of circle is 2πr.
R is radius of the circle and π is mathemetical constant which value approx 3.14
In the question it is given that the diameter of a wheel is 80m. So, radius is half of diameter, 40m.
So, the circumference = 2πr
= 2 × 3.14 × 40 = 251.2m
Rider has to travel 251.2m to cover one complete rotation.

Joe took $12 to the arcade. Each game cost $.50 to play. This situation can be modeled with the equation y + -.50 x+ 12. This represents the relationship between money Joe has remaining, y, and the number of games he plays, x. Use the function to determine the y-intercept.
State the meaning of the y-intercept in the terms of this problem
Answer: Joe has initial amount of $12 ( when he played no game).
Step-by-step explanation:
Given: Joe took $12 to the arcade. Each game cost $.50 to play.
This situation can be modeled with the equation [tex]y =-0.50 x+ 12.[/tex]
Here,
Money Joe has remaining is repreesnted by 'y', and the number of games he plays is represented by 'x'.
Since y-intercept gives the initial value of the function when x=0.
To find y-intercept , we out x=0 in funtion , we get
[tex]y=-0.50(0)+12=12[/tex]
So , y-intercept of this function is at y=12.
Meaning of the y-intercept in the terms of this problem :
Joe has initial amount of $12 ( when he played no game).
Answer:
y-intercept is 12 and y-intercept shows the fixed cost of arcade, i.e., $12.
Step-by-step explanation:
Note : The given equation is not correct.
It is given that Joe took $12 to the arcade and each game cost $0.50 to play.
This situation can be modeled with the equation
[tex]y=0.50x+12[/tex]
where, y is total cost of playing x games.
We need to find y-intercept.
Substitute x=0 in the above equation to find the y-intercept of the equation.
[tex]y=0.50(0)+12[/tex]
[tex]y=0+12[/tex]
[tex]y=12[/tex]
So, the y-intercept is 12.
Here y-intercept represents the total cost if the number of games is zero.
It means y-intercept shows the fixed cost of arcade, i.e., 12.

Three of the vertices of a trapezoid are A(3,-3), B(12, 6) and C(4,8). The fourth vertex is labeled D. One of its bases is AB
What is the equation of the line that includes base CD?
Answer:
y = x + 4
I graphed all the points, and the line that goes through AB is y = x - 6. The bases of a trapezoid are parallel, so the slope on the line CD has to be the same. I graphed the point C and just tried different y-intercepts to see which line would go through C.

If an event is likely to occur, the probability that the event will occur is between 3/4 and 1.
What is the probability?
Probability determines how likely it is that an event would happen. The probability the event occurs is 1 and the probability that the event does not occur is 0.
If the probability lies between 0 and 1/5, it is likely that the event would not occur. If the probability lies between 1/5 and 1, it is likely that the event would occur.

Which tree diagram shows all of the possible outcomes for tossing a coin and rolling a fair number pyramid that
has four sides labeled 1 through 4?
Answer:
D : This is because there are 8 outcomes and 2 events.
It cannot be C as C does not show true event outcomes on each H or T event.
Step-by-step explanation:
Tree diagram (D) shows all of the possible outcomes for tossing a coin and rolling a fair number pyramid that has four sides labeled 1 through 4 option (D) is correct.
What is probability?It is defined as the ratio of the number of favorable outcomes to the total number of outcomes in other words the probability is the number that shows the happening of the event.
We have a coin:
The coin has two faces: head and tail
possibility set = {H, T}
Number of total possible outcomes = 2
In a pyramid that has four sides labeled 1 through 4:
possibility set = {1, 2, 3, 4]
So a number of possible outcomes = 4
If the tossing a coin and rolling a fair number of pyramid
So the number of possible outcomes = 2×4 = 8
Thus, tree diagram (D) shows all of the possible outcomes for tossing a coin and rolling a fair number pyramid that has four sides labeled 1 through 4 option (D) is correct.

A point (3, –2) is reflected across the x-axis followed by a reflection across the y-axis. Find the image of the point after the described transformations. answers: A) (3, –2) B) (3, 2) C) (–3, –2) D) (–3, 2)
Answer:
D. (-3, 2)
Step-by-step explanation:
The original point is (3, -2)
The rule for reflecting across the x-axis is (x, y) -> (x, -y)
(3, -2) -> (3, 2)
The rule for reflecting across the y-axis is (x, y) -> (-x, y)
(3, 2) -> (-3, 2)
We want to find the image of the point (3, -2) after two reflections.
The correct option is D: (-3, 2)
Now let's see how to solve this.
The first thing we need to do is describe the two reflections.
For a general point (x, y), a reflection across the x-axis will give the point (x, -y).
And a reflection across the y-axis will give the point (-x, y).
So, if we start with the point (3, -2).
Then we reflect this across the x-axis, it gives the point: (3, -(-2)) = (3, 2)
Now we have a reflection across the y-axis, it gives the point (-3, 2)
So the image of the point after the two reflections is (-3, 2), meaning that the correct option is D.

where, n is an integer.
The given angle is
