is the relation a function? why
Answer:
no its not
Step-by-step explanation:
x-11 is only supposed to have one y.
if its a funtion then x should only have one line comming out of it. if its not a finction then x has two lines coming out of it.
Answer: no because the x axis dont equal or match up with the y axis and because theres not a certain amount of numbers for it to equal to or match to.
Step-by-step explanation:
A function is a relation in which each input has only one output. In the relation , y is a function of x, because for each input x (1, 2, 3, or 0), there is only one output y. x is not a function of y, because the input y = 3 has multiple outputs: x = 1 and x = 2. please give me brainliest
A town's population of children increased from 376 to 421 during the past year. Which equation shows how to find the percent increase? a p=421−376376 b p=421−376421 c p=376421−376
Answer:
a. p=421−376/376
Step-by-step explanation:
Computation for Which equation shows how to find the percent increase
Percentage increase=421-376/376*100
Percentage increase=45/376*100
Percentage increase=11.968%
Percentage increase=11.97% (Approximately)
Based on the above calculation The equation that will shows how to find the percent increase of the town's population of children from 376-421 during the past year will be:p=421-376/376

Flying against the wind, an airplane travels 5040 kilometers in 6 hours. Flying with the wind, the same plane travels 6000 kilometers in 5 hours. What is the rate of the plane in still air and what is the rate of the wind?
Answer:
The rate of plane in still air is 1020 kilometers per hour and rate of wind is 180 kilometers per hour.
Step-by-step explanation:
Given that:
An airplane travels 5040 kilometers in 6 hours against the wind
An airplane travels 6000 kilometers in 5 hours with the wind
Let,
x be the speed of plane in still air
y be the rate of wind
Combined speed against the wind = x - y
Combined speed with the wind = x+y
Speed = [tex]\frac{Distance}{Time}[/tex]
x-y= [tex]\frac{5040}{6} = 840[/tex]
x - y = 840 Eqn 1
x + y = [tex]\frac{6000}{5} = 1200[/tex] Eqn 2
Adding Eqn 1 and 2
x+y+x-y=1200+840
2x=2040
Dividing both sides by 2
[tex]\frac{2x}{2}=\frac{2040}{x}\\x=1020[/tex]
Putting x=1020 in Eqn 2
1020+y=1200
y=1200-1020
y=180
Hence,
The rate of plane in still air is 1020 kilometers per hour and rate of wind is 180 kilometers per hour.
The ratio of cats to dogs at April's Animal Shelter was 3 to 2. How many dogs were in the shleter if there were a total of 75 cats and dogs in the
shelter?
A 30
B 25
c 50
d 150
Answer:
A:30
Step-by-step explanation:
because 3+2(the ratio) =5
75(the total number or both) divide by 5
so 1 ratio=15
15 x 2(the ratio of dogs)
=30

The school store received a shipment of notebooks and pens. There are 10 cartons of notebooks and 25 boxes of pens. Each carton of notebooks costs $72 and contains 48 notebooks. Each box of pens costs $12.60 and contains 36 pens. The school wants to make a 10% profit.
question What is the cost of one notebook? What amount must be added on to the notebook's cost to account for a 10% markup? What will be the retail price (price the school is charging) for the notebook?
Answer:
cost of one notebook: 72/48 = $1.50
10% mark up = $1.50 x 0.10 = 0.15 cents
retail price = $1.65

4. The average speed of an Express train between New Delhi and Kota is 97 km/hr. The train
takes 4 hr to travel from New Delhi to Kota. Find the distance between New Delhi and Kota.
Answer:
Distance between New Delhi and Kota = 388 kilometers
Step-by-step explanation:
Given that:
Average speed of express train = 97 kilometer per hour
Time taken to travel = 4 hours
Distance between New Delhi and Kota = Speed * Time
Distance = 97 * 4
Distance = 388 kilometers
Hence,
Distance between New Delhi and Kota = 388 kilometers

Substitute the known value of x into y=4x+20. Then solve for y entering the equation in simplest form
Answer:
[tex]y=24,[/tex] when [tex]x=1[/tex].
Step-by-step explanation:
Given: [tex]y=4x+20[/tex]
To find: Value of [tex]y[/tex], substituting the known value of [tex]x[/tex]
We have,
[tex]y=4x+20 ...(i)[/tex]
Putting [tex]x=1[/tex] in equation [tex](i)[/tex], we get
[tex]y=4(1)+20[/tex]
[tex]\implies y=4+20[/tex]
[tex]\implies y=24[/tex]
Hence, the value of [tex]y[/tex] is [tex]24[/tex], when the value of [tex]x[/tex] is [tex]1[/tex].

A line has this equation: -5y = 4x+40
Write an equation for the perpendicular line that goes through (8,5).
Answer:
The equation of the second line is;
y = 4x - 27
Step-by-step explanation:
Firstly, we need the slope of the first line
To get the slope, we need the equation in the general form of ;
y = mx + c
where m is the slope of the line
Thus, we have in this case, to divide through by -5
That will give the slope value as -5/20 = -1/4
If two lines are perpendicular, the product of their slopes is -1
The slope of the line we want to calculate, let us call it m
m * -1/4 = -1
-m = -4
m = 4
So we want to write the equation of a line with slope 4 and point (8,5)
We proceed to use the point-slope form
That will be;
y-y1 = m(x-x1)
y-5 = 4(x-8)
y-5 = 4x-32
y = 4x -32 + 5
y = 4x -27
Polygon ABCD has the following vertices:
A(−4, 2), B(3, 2), C(3, −5), and D(−4, −2)
Calculate the area of the polygon.
28 units squared
38.5 units squared
40.5 units squared
49 units squared
9514 1404 393
Answer:
(b) 38.5
Step-by-step explanation:
The polygon is a trapezoid with bases 4 and 7 and height 7. Its area is given by the formula ...
A = (1/2)(b1 +b2)h
A = (1/2)(4 +7)(7) = 77/2
A = 38.5 . . . . square units

Mr bell bought a freezer in a sale where all goods were 20% off. what was the original price of the freezer?
Answer:
First, you did not exactly state what the original price was or maybe that's how the question is worded, but in this scenario the original price of the freezer would be x because they did not tell us.
Step-by-step explanation:
A 20 percent discount is 0.20 in decimal format. For example if the original price was $20, then you would multiply 0.2 by $20 to get $4.00. In this question i would say the original price would be x, so then it would be 0.2x.
Hope this helps:)
