A.5x=20
B.8x-32
C.-4x=16
D.x/2=2
E.x/4=16
Answers
Answer:
a and d
Step-by-step explanation:
5x = 20
5/5x = 20/5
x = 4
8x = -32
x = -4
-4x = 16
x = -4
x/2 = 2
2*x/2=2*2
x = 4
x/4 = 16
4*x/4 = 16*4
x = 64
The equations 5x = 20 and x/2 = 2 are that have a solution of 4 which is the correct answer would be options (A) and (D).
What is the equation?The equation is defined as mathematical statements that have a minimum of two terms containing variables or numbers that are equal.
We have to determine the solution of all the given equations.
5x = 20
x = 20/5
Apply the division operation, and we get
x = 4
This is the required solution.
8x = -32
x = -32/8
Apply the division operation, and we get
x = -4
-4x = 16
x = 16/4
x = -4
x/2 = 2
2×x/2=2×2
x = 4
This is the required solution.
x/4 = 16
4×x/4 = 16×4
x = 64
Therefore, the correct answer would be options (A) and (D).

Answers
Given:
The data set is 60, 74, 70, 70, 50, 62, 54, 89, 67, 88, 82, 74.
To find:
The IQR and outliers.
Solution:
The given data set is
60, 74, 70, 70, 50, 62, 54, 89, 67, 88, 82, 74
Arrange the data values in ascending order.
50, 54, 60, 62, 67, 70, 70, 74, 74, 82, 88, 89
Divide the data set in two equal parts.
(50, 54, 60, 62, 67, 70), (70, 74, 74, 82, 88, 89)
Divide each parentheses in two equal parts.
(50, 54, 60), (62, 67, 70), (70, 74, 74), (82, 88, 89)
Now,
[tex]Q_1=\dfrac{60+62}{2}[/tex]
[tex]Q_1=\dfrac{122}{2}[/tex]
[tex]Q_1=61[/tex]
And,
[tex]Q_3=\dfrac{74+82}{2}[/tex]
[tex]Q_3=\dfrac{156}{2}[/tex]
[tex]Q_3=78[/tex]
We know that, the inter quartile range is
[tex]IQR=Q_3-Q_1[/tex]
[tex]IQR=78-61[/tex]
[tex]IQR=17[/tex]
The IQR is 17.
If the data values lie outside the interval [tex][Q_1-1.5IQR,Q_3+1.5IQR][/tex], then those values are known as outliers.
[tex][Q_1-1.5IQR,Q_3+1.5IQR]=[61-1.5(17),78+1.5(17)][/tex]
[tex][Q_1-1.5IQR,Q_3+1.5IQR]=[35.5,103.5][/tex]
All data values lie in the interval [35.5,103.5]. So, there are no outliers.
Therefore, the correct option is B.

The axis of symmetry is the horizontal shift. If I am not wrong, you might be learning about absolute value functions or parabolas.
The absolute value function: f(x)= a|x-h|+k
The parabola (Vertex form of a quadriceps function): f(x)= a(x-h)^2+k

Please make sure the answer is correct
Answers
Answer:
B
Step-by-step explanation:
First, find the slope by using change in y divided by change in x.
Change in y = 5 - 2 = 3
Change in x = 2 - 1 = 1
This means that the slope is 3/1 = 3.
Then, you put it in the point-slope form so:
(y - 2) = 3(x - 1)

C. nine over twenty
Step-by-step explanation:
First we should do all of the dividing of the fractions
8/20 = .4 = 40%
9/25 = .36 = 36%
9/20 = .45 = 45%
8/25 = .32 = 32%

H varies directly to the cube of c. When H =40 c=2. find the value of when H=5000
Answers
Answer:
c = 10
Step-by-step explanation:
Given that H varies directly as c³ then the equation relating them is
H = kc³ ← k is the constant of variation
To find k use the condition when H = 40, c = 2 , then
40 = k × 2³ = 8k ( divide both sides by 8 )
5 = k
H = 5c³ ← equation of variation
When H = 5 000, then
5000 = 5c³ ( divide both sides by 5 )
1000 = c³ ( take the cube root of both sides )
[tex]\sqrt[3]{1000}[/tex] = c , so
c = 10

Speed is the ratio of distance and time.
It shows how fast an object is moving at a given time.
Speed = Distance / Time
The rate of the rowing team in still water is 9 miles per hour.
What is speed?Speed is the ratio of distance and time.
It shows how fast an object is moving at a given time.
Speed = Distance / Time
We have,
The speed of the current:
V = 3 miles per hour
Rowed with the current:
Speed = V + 3
Distance = 60 miles
Rowing against the current:
Speed = V - 3
Distance = 30 miles
Rowing with the current and against the current took the same time.
Speed = Distance / Time
Time = Distance / Speed
Now,
Time for rowing with the current = Time for rowing against the current
60 / (V + 3) = 30 / (V - 3)
2 / (V + 3) = 1 / (V - 3)
2 (V - 3) = V + 3
2V - 6 = V + 3
2V - V = 3 + 6
V = 9
Thus,
The rate of the rowing team in still water is 9 miles per hour.

The slope of the line that passes through the point (3, -10.5) and (7.-28.5) will be -5
What is the slope?The slope is the ratio of the vertical changes to the horizontal changes between two points of the line.
The slope of the line is calculated as follows:
m = Δy/Δx
Given that the line that passes through the points (3, -10.5) and (7.-28.5)
To find the slope of the line that passes through points (3, -10.5) and (7.-28.5).
Therefore, the slope of the line is;
m = Δy/Δx
m = (-28.5- 10.5)/(7 - 3)
m = -20/4
When we simplify it, then we get;
m = -5
Hence, the slope of the line is -5.

Skylar has a points card for a movie theater. She receives 85 rewards points just for signing up. She earns 7.5 points for each visit to the movie theater. She needs 160 points for a free movie ticket. Write and solve an equation which can be used to determine x, the number of visits Skylar must make to earn a free movie ticket.
Answers
In order to win the free movie ticket, Skylar must visit the theater 10 times
The equation that can be used to represent the explanation given in the question is : 160 = 85 + 7.5x
The 85 reward points that Skylar gets for signing up can be likened to fixed point. This point does not change with the number of theater visits.The 7.5 points she earns for each visit to theater can be described as variable point. This point increases with the number of theater visits. The total number of points she can earn from a cinema visit = 7.5 × x = 75x.where x represents the number of cinema visits
Given this equation: 160 = 85 + 7.5x, take the following steps to determine the number of visits Skylar needs to earn the movie ticket:
Combine similar terms
160 - 85 = 7.5x
75 = 7.5x
Divide both sides of the equation by 7.5
75 / 7.5 = x
x = 10
