The mapping diagram shows a functional relationship. A mapping diagram shows a relation, using arrows, between domain and range for the following ordered pairs: (negative 1, 0), (0, 3), (3, negative 1), (9, 9). Complete the statement. f(3) is .
Answer:
-1
Step-by-step explanation:
The value of f(3) is -1.
What is a Mapping Diagram?A mapping diagram is an image of two circles which shows two values corresponding to each other, such that one is the input value to the function and the other is the output value.
The input value circle represents the domain of the function and the output value circle represents the range of the function.
To check if the mapping diagram shows a function, it is observed that one input value is connected to only one output value.
The input and output value in the mapping diagram is:
(negative 1, 0), (0, 3), (3, negative 1), (9, 9).
The domain of the function is ( -1 , 0 , 3 , 9)
The range of the function is ( 0 , 3 , -1 , 9)
The value of f(3) is the value of function at input value of 3.
f(3) = -1

24. Janet and Jack are walking in a two-day event to raise money for charity.
Janet asks a friend for a $7.50 donation, plus $0.10 for each mile she
walks. Jack asks a friend for a $5.50 donation, plus $0.15 for each mile
he walks. At how many miles of walking would Janet and Jack collect the
same amount of money?
Answer:
40 miles walk
Step-by-step explanation:
Let the miles walked by both of them be x at which money collected by same
for Janet
Fixed donation asked = $7.50
money asked for walking 1 mile = $0.10
money made by Janet if he walks x miles = x*$0.10 = $0.10x
Total money collected by Janet = Fixed donation asked + money made by Janet if he walks x miles
Total money collected by Janet =7.50 + 0.10x
For Jack
Fixed donation asked = $5.50
money asked for walking 1 mile = $0.15
money made by Janet if he walks x miles = x*$0.15 = $0.15x
Total money collected by Jack = Fixed donation asked + money made by Jack if he walks x miles
Total money collected by Jack =5.50 + 0.15x
we have to find miles at which money collected by both of them be same
and we have decided that it it as x mile walk then
Total money collected by Janet = Total money collected by Jack
7.50 + 0.10x = 5.50 + 0.15x
=> 7.50 - 5.50 = 0.15x - 0.10x
=> 2 = 0.05x
=> x = 2/0.05 = 40
Thus, at 40 miles walk money collected by both of them will be same

Hadley earned 8 more points on her test than Adam earned. Their points add up to 162. How many points did each student earn ?
Answer:
Adam - 77 / Holly - 85
Step-by-step explanation:
x + (x + 8) = 162
2x + 8 = 162
2x = 154
x = 77
x = Adam
x + 8 = Holly
Therefore, Adam - 77 / Holly - 85.

Calculate the slope between the points: (4, -9) and (5, 1)
a
m=10
b
m=1/10
с
m=-10
d
m=-1/10
Answer:
The answer is A- m=10
Step-by-step explanation:
The way to find slope is known as "Rise over Run" meaning the increase of Y over the increase of X. The increase of Y is 10 because 1 - (-9) = 10. The increase of X is 1 because 5 - 4 = 1. 10 over 1, or 10 / 1, equals 10.

The Sum Of Two Numbers Is 18 And Their Difference Is 4
Answer:
The two numbers are 7 and 11.
[711? Is this an ad? ← :)]
Step-by-step explanation:
Let A and B stand for the two numbers.
We are told that:
1) A+B=18, and
2) A-B=4
Take the first expression and rearrange to isolate A:
A+B=18
A=18-B
Use this in the second expression:
(18-B)-B=4
-2B = -14
B = 7
From (1) we find A:
A+B=18
A+7=18
A= 11
If A=11, then B=7 (from A+B=18)
CHECK:
Does A+B=18?
11 + 7 = 18? YES
Does A-B=4?
11 - 7 = 4? YES

Marco has saved $279 for karate lessons. He bought a uniform for $56 and pays $14 per class. Which inequality represents the number of classes, c, Marco can take and stay within his budget
Answer:
B.
Step-by-step explanation:
Since the main goal for Marco is to stay under his budget which is 279, it's expected that he would want to spend less than or equal to his budget and that is the point to spend less than our goal of spending limit. If the cost of uniform and the cost of each of his classes are less than how much money he wants to spend, than that is going to still be within his budget even if the equation equals to 279 it is still within his budget anything greater would be consider over spending past his budget. Therefore making all other equations false.

Which of these equations, when solved, gives a different value of x than the other three? 9.1 = -0.2x + 10 10 = 9.1 + 0.2x 10 – 0.2x = 9.1 9.1 – 10 = 0.2x To prepare for his mountain biking trip, Rhyan bought four tire patches. Rhyan paid using a gift card that had $22.20 on it. After the sale, Rhyan's gift card had $1.90 remaining. Which equations could you use to find the price of one tire patch? Select all that apply. 4x – 1.9 = 22.2 4x – 22.2 = 1.9 4x + 1.9 = 22.2 4x + 22.2 = –1.9 22.2 – 4x = 1.9
Given:
Different equations are given.
Rhyan paid using a gift card that had $22.20 on it. After the sale, Rhyan's gift card had $1.90 remaining.
To find:
The equation which gives a different value of x than the other three.
To find the equations that could you use to find the price of one tire patch.
Solution:
In option A,
[tex]9.1 = -0.2x + 10[/tex]
[tex]0.2x= 10-9.1[/tex]
[tex]0.2x= 0.9[/tex]
Divide both sides by 0.2.
[tex]x=\dfrac{0.9}{0.2}[/tex]
[tex]x=4.5[/tex]
Similarly,
In option B,
[tex]10 = 9.1 + 0.2x[/tex]
[tex]0.9= 0.2x[/tex]
[tex]4.5=x[/tex]
In option C,
[tex]10-0.2x = 9.1[/tex]
[tex]-0.2x = -0.9[/tex]
[tex]x = 4.5[/tex]
In option D,
[tex]9.1 – 10 = 0.2x[/tex]
[tex]-0.9 = 0.2x[/tex]
[tex]-4.5 = x[/tex]
Since option D has difference solution, therefore the correct option is D.
Let price of one tire patch be x.
So, price of 4 tire patches = 4x
Remaining amount in Rhyan's gift card = $1.90
Total amount = $22.20
Price of 4 tire patches + Remaining amount in gift card = Total amount
[tex]4x+1.9=22.2[/tex]
It can be written as
[tex]4x-22.2=-1.9,1.9=22.2-4x,22.2-4x=1.9[/tex]
Therefore, the correct options are C and E.
