What is the equation in point−slope form of the line passing through (1, 2) and (2, 5)?
(5 points)
A.) (y − 2) = −3(x − 1)
B.) (y − 2) = 3(x − 1)
C.) (y − 1) = −3(x − 2)
D.) (y + 2) = 3(x + 1)
Please make sure the answer is correct
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)
If 8 more than twice a number is equal to 20, what is 6times the number ?
Answer:
36
Step-by-step explanation:
2x + 8 = 20
2x = 20 - 8
2x = 12
x = [tex]\frac{12}{2}[/tex]
x= 6
6x
6(6) = 36

The length of a rectangular building is 4 feet more than 3 times the width. The perimeter is 84 feet. Find the width and length of the building.
Answer:
Width=9.5, Length=32.5
Step-by-step explanation:
Let x be the width of the rectangle,
The length is 4 feet more than 3 times the width,
The length= 3x+4
The perimeter is
2(x)+2(3x+4)=84
2x+6x+8=84
8x=76
x=76/8
x=9.5
The Width=9.5
Length= 3(9.5)+4=32.5

Find the interquartile range (IQR) and list any outliers: 60, 74, 70, 70, 50, 62, 54, 89, 67, 88, 82, 74 A. IQR = 39: 89 is an outlier B. IQR = 17: no outliers C. IQR = 39: no outliers D. IQR = 17: 50 is an outlie
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.

Guys please which one is the right answer. I need help
Answer:
The equation would be 8n + 11 = 3n + 26.
Answer:
I'm gonna assume we're talking about "n".
b) 8n+11=3n+26 (because they are corresponding angles)
n=3
Step-by-step explanation:
8n+11=3n+26
simplifying:
8n-3n+11-11=3n-3n+26-11
5n=15
n=3
(13a² − 6a⁵ − 2a) − (−10a² − 11a⁵ + 9a)
Answer:
a x (23a+5a^4 - 11)
Step-by-step explanation:
(a x (13a - 6a^4 - 2) + 10a^2 + 11a^5 - 9a
rewite the expression and remove any unnecessary parentheses.
a x (13a - 6a^4 -2) + 10a^2 +11a^5 - 9a
factor the expression.
a x (23a - 6a^4-2+11a^4-9)
connect like terms.

- What is the slope of a line that passes through the points (3, -10.5) and (7.-28.5)?
A
-2/9
B
-9/2
c
2/9
D
9/2
Answer:
It is B
Hope this helps!
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.

Two functions are given below f(x) and h(x) State the axis of symmetry for each function and explain how you found it
Answer:
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
The variable ‘h’ is the horizontal shift, in other words, the axis of symmetry
