Answer:
No, The domains of a same number are said twice.
Step-by-step explanation:
If it is the range (y) it doesn't matter twice or not.
Answer:
The given relation is not a function.
Step-by-step explanation:
Given the relation: {(3,2) (8,16) (13,8) (14,14) (20,5) (24,8) (27,2) (31,6) (31,3)}
A relation is any set of ordered pairs, which can be thought of as (input, output).
A function is a relation in which no two ordered pairs have the same first component (x-values or input) and different second components (y-values or output).
We need to ask ourselves, does every first element (or input) correspond with EXACTLY ONE second element (or output)? In this case, the answer is no. The input value (x = 31) goes with two output values, 6 and 3. It only takes one input or x-value to associate with more than one output value to be invalid as a function.Another way to find out whether a relation or a set of given points represent a function through the Vertical Line Test. If a vertical line intersects the graph in all places at exactly one point, then the relation is a function.
To use the vertical-line test, imagine dragging a ruler held vertically across the graph from left to right. If the graph is that of a function, the edge of the ruler would hit the graph only once for every x -value. If you do this for the given set of points, every vertical line intersects the graph in at most one point, except for the x-value = 31, where the vertical line contains two points (in red dots) in it: (31,6) and (31,3). The given graph fails the Vertical Line Test, which means that it is not a function.
Attached is a screenshot of the graph where I performed the Vertical Line Test.

Write the equation of the line in fully simplified slope intercept form
Answers
Answer:
y = 6x - 5
Step-by-step explanation:
In order to determine the slope-intercept form, y = mx + b, of the given line:
You need to find the slope (m) and determine the y-intercept (b).
Given the points (1, 1) and (0, -5):
Let (x1, y1) = (1, 1)
(x2, y2) = (0, -5)
Use the following formula for slope:
m = (y2 - y1)/(x2 - x1)
m = (-5 - 1)/(0 - 1)
m = -6/-1
m = 6
The slope of the line is 6.
Next, the y-coordinate (b) of the point, (0, b ) is the y-intercept of the line where the graph of the linear equation crosses the y-axis. The y-intercept is also the value of y when x = 0.
Looking at the graph, you'll see that the line crosses at point (0, -5). We used this point earlier to solve for the slope. Hence, the y-coordinate, b = -5, is the y-intercept.
Given the slope, m = 6, and the y-intercept, b = -5:
The linear equation in slope-intercept form is: y = 6x - 5.

Step-by-step explanation:
let a, b, c represent the number of students in 6th, 7th, 8th grade
ratio of students : teachers = 28 : 1
There are 82 teachers , so 28 × 82 = 2296 students
Then
a + b + c = 2296 , that is
828 + b + c = 2296 ( subtract 828 from both sides )
b + c = 1468 → E
find the measure of the indicated angle
Answers
Answer:
∠ E = 57°
Step-by-step explanation:
Since DF = EF then the triangle is isosceles with 2 base angles congruent , so
∠ E = ∠ D = 4x + 1
The sum of the 3 angles in the triangle = 180°
Sum the 3 angles and equate to 180
4x + 1 + 4x + 1 + 5x - 4 = 180 , collect like terms
13x - 2 = 180 ( add 2 to both sides )
13x = 182 ( divide both sides by 13 )
x = 14
Then
∠ E = 4x + 1 = 4(14) + 1 = 56 + 1 = 57°

What is the length of the arc?
Either enter an exact answer in terms of \piπpi or use 3.143.143, point, 14 for \piπpi and enter your answer as a decimal.
Answers
Answer:
length of arc ≈ 17.8 (to the nearest tenth)
Step-by-step explanation:
To find the length of the arc we use the formula for finding length of an arc.
length of arc = ∅/360 × 2πr
where
∅ = central angle
r = radius
∅ = 340°
r = 3
length of arc = ∅/360 × 2πr
length of arc = 340/360 × 2 × π × 3
length of arc = 340/360 × 6π
length of arc = 2040π/360
length of arc = 204π/36
length of arc = (204 × 3.14)/36
length of arc = 640.56/36
length of arc = 17.7933333
length of arc ≈ 17.8 (to the nearest tenth)
