The function f(x)=x has a domain and target of the set of Real numbers. To describe this function, we need to consider its one-to-one and onto properties. A function is one-to-one if each element of the domain is mapped to a unique element of the target, and a function is onto if every element of the target is mapped to by at least one element of the domain. In this case, the function f(x)=x is one-to-one and onto, making it a bijection. Therefore, the most appropriate way to describe this function is option b: f is a bijection.
To determine the appropriate way to describe the function f(x)=x, we need to consider its one-to-one and onto properties. A function is one-to-one if each element of the domain is mapped to a unique element of the target, and a function is onto if every element of the target is mapped to by at least one element of the domain. In this case, for every x in the domain of Real numbers, there is a unique value of x in the target of Real numbers. This means that the function is one-to-one. Additionally, every element in the target is mapped to by at least one element in the domain. Therefore, the function is also onto. Since the function is both one-to-one and onto, it is a bijection.

Answer:
anser A
Step-by-step explanation:
Let's fill x and y and we'll see which one is right
a) 0 = -3(-7+7)(-7+4)
<=> 0 = 3 * 0 * -3
<=> 0 = 0 => true
b) 0 = -0.5(-7-7)(-7+4)
<=> 0 = -0.5 * -14 * -3
<=> 0 = -21 => false
c) 0 = (-7-7)(-7-4)
<=> 0 = -154 => false
d) 0 = 2(-7+7)(-7-4)
<=> 0 = 0 => true
so both a and d are right for (-7,0). Now let's for (-4,0)
a) 0 = -3(-4+7)(-4+4)
<=> 0 = 0 => true
d) 0 = 2(-4+7)(-4-4)
<=> 0 = -48 => false

Answer:
Sean is incorrect.
Step-by-step explanation:
The interior angle of this triangle with the exterior angle of 80° is 100°, so the sum of the remaining angles should be 80°, which means (X + 5) + (X - 5) = 80. Take off the parenthesis, 2X = 80, which means X = 40°. This is where Sean's answer was wrong, he forgot that the remaining angles are X + 5 and X - 5 instead of X, which means that the angles in this triangle should actually be 100°, 45°, and 35°.

Answer:
2.4 miles per hour
Step-by-step explanation:
1/5 of a mile is 0.2 miles. If 0.2 miles is 5 minutes, then 0.04 miles is 1 minute, as you divide 0.2 by 5. 0.04 miles per minute=2.4 miles per hour as you times 0.04 by 60.
a woman is 5 times as old as her daughter in 15 years time to be two times as old as her daughter to find a mother's presentsage
Answer:
25 years.
Step-by-step explanation:
Given that a woman is 5 times as old as her daughter, while in 15 years time it will be two times as old as her daughter, to find a mother's presents age the following calculation must be performed:
5 x 5 = 25
25 + 15 = 40
40/2 = 20
5 + 15 = 20
Thus, the present age of the mother is 25 years, while that of her daughter is 5 years, with which the mother is five times the age of her daughter. In 15 years, the mother will be 40 and her daughter 20, with which she will only be twice her age.

Answer :
The function is
Step-by-step explanation:
Given values in table :
x f(x)
3 -1
4 0
5 1
6 2
Here we see there is a difference of 4 in the values of x and f(x)
i.e. 3-(-1)=4
or 4-0=4
Similarly 5-1=4
6-2=4
So x-F(x)=4
Adding F(x) -4 both sides
x-F(x) +F(x) -4=4+F(x) -4
We have F(x)= x-4

A bakery made 1, 575 butter cookies. After arranging the cookies into packages, the bakery did not have any cookies left. How many cookies could have in each package? *
1 point
A. 6
B. 5
C. 9
D.4
Answer:
B. 5 might be the answer.
Answer: Either B. 5 or C. 9
Explanation: Assuming there would be the same amount of cookies in each package, to see if they would all fit perfectly and there be no leftover cookies, simply divide 1,575 (the number of total cookies) by how many cookies could be in each package. If it comes out with "point something," then the numbers after the decimal point would be how many cookies will be leftover. 5 and 9 both end up with no decimal, so that's as much as I know.

When two angles of an isosceles triangle are given in the form of x, then the value of a single angle can have two possible outcomes those are:
X can be [tex]56.66^\circ[/tex]X can be [tex]53.33^\circ[/tex]Given,
Two angles: X and [tex]\rm{X}+10[/tex]
As we know in an Isosceles triangle, the sum of all the angles is equal to[tex]180^\circ[/tex] and any of the two angles can be equal.
There can be two possible outcomes:
Case 1. When the two equal angles are X
[tex]\begin{aligned}\text{X}+\text{X}+(\text{X+10})&=180\\3\text{X}+10&=180\\3\text{X}&=180-10\\\text{X}&=\dfrac{170}{3}\\\text{X}&=56.66^\circ\end{aligned}[/tex]
Case 2: When the two equal angles are [tex]\rm{X}+10[/tex]
[tex]\begin{aligned}\text{X}+(\text{X}+10)+(\text{X}+10)&=180\\3\text{X}+20&=180\\3\text{X}&=180-20\\\text{X}&=\dfrac{160}{3}\\\text{X}&=53.33^\circ\end{aligned}[/tex]
Therefore, the two possible values of X can be [tex]56.66^\circ[/tex] and [tex]53.33^\circ[/tex]

2--------- $3
3--------- $4.50
5--------- $7.50
Answer:
proportional relationship. Exist
Step-by-step explanation:
To check for propottionality:
2 = 3k
Solve for k = constant of proportionality
2/3 = 3k/3
2/3 = k
Quantity at price = 4.50
Price * k = quantity
4.50 * 2/3 = 3
Quantity at price = 7.50
Price * k = quantity
7.50 * 2/3 = 5
Hence, proportional relationship. Exist

Steve is turning half his backyard into a chicken fan. His backyard is a 24 m x 45 m rectangle. He wants to put a chicken wire fence that stretches diagonally from one corner to the opposite corner. How many meters of fencing will Steve need?
Answer:
51 meters
Step-by-step explanation:
Steve is turning half his backyard into a chicken fan. His backyard is a 24 m x 45 m rectangle. He wants to put a chicken wire fence that stretches diagonally from one corner to the opposite corner. How many meters of fencing will Steve need?
We are to find the meters of fencing for the diagonal.
We solve the question using Pythagoras Theorem
= c² = a² + b²
Where
c = Diagonal
a = Width
b =Length
Diagonal² = Width² + Length ²
Hence:
Diagonal ² = 45² + 24²
Diagonal = √45² + 24²
Diagonal = √(2601)
Diagonal = 51 m
Therefore, the meters of fencing for the diagonal that Steve would be needing = 51 meters

O y = 5.50x + 20
O None of the other answers are correct
O y = 65x
O y = 60x + 300
O y = -x + 56
Answer:

Step-by-step explanation:
A linear equation is an equation in which each term has at max one degree. The correct option is D, y = -x + 56.
What is a linear equation?A linear equation is an equation in which each term has at max one degree. Linear equations in variables x and y can be written in the form,
y = mx + c
Linear equation with two variables, when graphed on the cartesian plane with axes of those variables, give a straight line.
Given that the temperature was 56 degrees this morning but dropped one degree per hour through the rest of the day. Therefore, an equation in slope intercept form to represent the temperature of the day at any given hour is,
y = 56 - x
y = -x + 56
Hence, the equation in slope intercept form to represent the temperature of the day at any given hour is y = -x + 56.
