Answer:
Ela segue esse modelo
f(x) = ax + b
Então, é só substituir os valores de x e de y na Lei de Formação
Ex: quando x=0, y=-1
y= ax+b
-1=a.0+b
b= -1
È onde a reta toca o eixo y, porque x=0
Agora, vamos usar outro par ordenado.
Quando x=2, y=3
3=a.2+(-1)
3=2a-1
3+1=2a
4=2a
a=4/2
a=2
A lei de formação é essa
a= 2; b=-1
f(x)= ax+b
f(x)=2x-1

Which graph shows a linear relationship? Select yes or no. For A B C D
Answers
Answer:
A, B, and C show linear relationships.
Step-by-step explanation:
For something to have a linear relationship, it CANNOT have an x-value with two different y-values.
To determine if something has two y-values for one x-value, pass a line (like a pencil) over the graph. If there are any places where the line crosses the graph twice, the graph you have is not linear.

Addicted to the Internet?The Ann Arbor public school officials would like to estimate the population mean daily Internet usage time for all Ann Arbor teens. To do so, a large random sample of Ann Arbor teens was selected. Here are the results of their study. The 95% confidence interval for the mean daily internet usage time for the population of all such Ann Arbor teens was found to be (6.7 hours, 9.3 hours).The 99% confidence interval or the mean daily internet usage time for the population of all such Ann Arbor teens was found to be (6.257 hours, 9.743 hours).The Ann Arbor public school officials know that you have some statistical background and would like your opinion. Please read each statement carefully and share with us your opinion.
Answers
Answer:
We can assure the Ann Arbor officials that after look the information we conclude that the mean is 8 h
Step-by-step explanation:
From CI ( 95 % ) = ( 6,7 ; 9,3 )
And the information "large random size sample" we conclude that the population has a normal distribution; a normal distribution has a bell shape curve, and data must spread symmetrically with respect to the mean, therefore the mean is:
6,7 + 9,3 = 16
16/2 = 8
If we need t check we can use the other CI
CI ( 99 % ) = (6,257 , 9,743 )
6,257 + 9,743 = 16
16/2 = 8
We are sure the mean is 8 h

How many degrees has •abc• been rotated counterclockwise about the origin?
A. 360*
B. 90*
C. 270*
D. 180*
Answers
Answer:
C- 270
Step-by-step explanation:
This is "counterclockwise":
- 90* : it will turn 1 left
- 180*: It will turn 2 left or upside down
- 270*:It turn 3 lefts or 1 right
- 360* :> It will turn 4 lefts or no change
I hope im right!!
The number of degrees has been rotated counterclockwise about the origin should be considered as the 90 degrees.
What is counter clock wise angle?If the rotation is counterclockwise, the angle has positive measure. If the rotation is clockwise, the angle has negative measure.
here, we have,
Rotating of the point:
At the time when the rotation is done with respect to the point so here it should be 90 degrees counterclockwise about the origin. Also, we have to switch x and y and make y to be negative.
Therefore, the first option is correct.
hence, The number of degrees has been rotated counterclockwise about the origin should be considered as the 90 degrees.

Fon baked a cake and ate 1/8 of it she shared the remaining cake equally to her 4 friends whag Frection of the whole cake did each of her friends received?
Answers
Answer:
Each of her friends ate 7/32 of the cake.
Step-by-step explanation:
Given that Fon baked a cake and ate 1/8 of it, and then she shared the remaining cake equally to her 4 friends, to determine what fraction of the whole cake did each of her friends received, the following calculation must be performed:
(8 - 1/8) / 4 = X
(7/8) / 4 = X
(28/32) / 4 = X
7/32 = X
Thus, each of her friends ate 7/32 of the cake.

What value of x would make the following relation a function?
Answers
Answer: the answer is
C.) -2
Step-by-step explanation:
I got this answer by simply looking at the pattern. It goes -2,-3,2,3, and then starts over, So the answer would have to be -2. I hope this helped and good luck:))
The value of x that would make the relation a function is x = 3.
Option D is the correct answer.
What is a function?A function is a relationship between inputs where each input is related to exactly one output.
Example:
f(x) = 2x + 1
f(1) = 2 + 1 = 3
f(2) = 2 x 2 + 1 = 4 + 1 = 5
The outputs of the functions are 3 and 5
The inputs of the function are 1 and 2.
We have,
{ (-2, -3), (-3, -2), (2, 3), (3, 2), (x, 2) }
A function can not be one-to-many.
A function can be many-to-one and one-to-one
Now,
If x = 2, -3, -2 we get one-to-many.
But if x = 3 we get one-to-one.
Thus,
x = 3.

Answer:
£592 for 16 boxes
Step-by-step explanation:
The classroom floor area is ...
A = LW = (8.8 m)(2.2 m) = 19.36 m²
The cupboard floor area is ...
A = (2.3 m)(2.1 m) = 4.83 m²
Then the total area to be covered is ...
19.36 m² +4.83 m² = 24.19 m²
At 1.6 m² per box, the number of boxes required is ...
(24.19 m²)/(1.6 m²/box) = 15.12 boxes
If we assume we can only purchase whole boxes, we need to purchase 16 boxes to cover the floor. The cost will be ...
(16 boxes)(£37/box) = £592 . . . . cost of laminate to replace the floor
