oints (−6, 3) and (−6, −3) on the coordinate grid below show the positions of two dogs at a park:
A coordinate plane is shown. There is a point at negative 6, 3 labeled Dog 1. There is a point at negative 6, negative 3 labeled Dog 2.
Which statement best describes the relationship between the positions of the two players? (4 points)
a
Dog 1's position is Dog 2's position reflected across the y-axis; only the signs of the y-coordinates of Dog 1 and Dog 2 are different.
b
Dog 1's position is Dog 2's position reflected across the x-axis; only the signs of the y-coordinates of Dog 1 and Dog 2 are different.
c
Dog 1's position is Dog 2's position reflected across the x-axis; only the signs of the x-coordinates of Dog 1 and Dog 2 are different.
d
Dog 1's position is Dog 2's position reflected across the y-axis; only the signs of the x-coordinates of Dog 1 and Dog 2 are different.
Answers
Answer: B
Explanation:
Correct way to write down co-ordinates: x,y
Dog 1's position: (-6,3)
Dog 2's position: (-6,-3)
Similarity: Both co-ordinates have -6 on the X axis (left to right line)
Difference: Dog 2's Y co-ordinate is NEGATIVE 3 while dog 1's Y co-ordinate is POSITIVE 3
The position is going to be reflected across the X axis because their X co-ordinates are the same, so dog 1 will be on the positive section for the Y axis (line that goes up and down) while Dog 2 will be on the negative section of the Y axis since it has negative 3 as its Y co-ordinate.

Jacinta drove from the mountains to the desert. She went from 8,560 feet above sea level to 122 feet below sea level.
If she drove at a constant speed for six hours, which statement represents her rate of change in elevation
(A) Jacinta descended at a rate of 732 feet per hour.
(B) Jacinta descended at a rate of 1,426 2/3 feet per hour.
(C) Jacinta descended at a rate of 1,406 1/3 feet per hour.
(D) Jacinta descended at a rate of 1,447 feet per hour.
Answers
Answer: D) 1,447 feet per hour
Step-by-step explanation:
8,560 + 122 = 8,682
8,682 ÷ 1,447 = 6
(For clarification, 6 × 1,447 = 8,682; 1,447 feet descended every hour.)

I need help on a b and function 2
I dont get it
Answers
Answer:
For A: The first function has a greater ROC
For B: The first function has a negative slope
Step-by-step explanation:
Explication for A:
We already know that the R.O.C. (slope) is 2 for the first function, so all we need to do is substitute the values in the table into the following formula: y2-y1/x2-x1
after substituting: (-3-(-6))/(0-(-1))
simplify 3/1=3, since the ROC is 3, the second equation has a greater ROC than the first
Explanation for B:
The first function described is f(x)=20-3.5x
This is because the y intercept is the starting point, or how much money she has in the gift card. She spends 3.5 dollars per week, so we add a variable to represent the number of weeks, and its negative since she is spending, not earning. We also know that the slope is negative since y is decreasing as x is increasing, on the table.
The second function described is c(m)=5x+10
This is because the equation represents the total cost of renting a calculator, so both terms are positive.
For each ride, a taxi service charges an initial fee plus an additional fee based on the number of kilometers of the trip. The graph shows the cost for taxi rides. Select a true statement. The rise is 4 while the run is 2. The selection of answers are:
A: The slope is 2.1. This means that each kilometer costs $2.10.
B: The slope is 5. This means that each kilometer costs $5.
C: The y-intercept is 2.1. This means that the initial fee is $2.10.
D: The y-intercept is 5. This means that the ride lasts 5. kilometers.
Which one is right and why?
Answers
THIS MIGHT NOT BE WHAT YOU ARE LOOKING FOR AND MIGHT NOT BE CORRECT! READ FIRST!
The answer is A. The slope of the line is rise/run = 4/2 = 2.1. This means that each kilometer costs $2.10. The y-intercept is 2.1, which means that the initial fee is $2.10. So the correct statement is: The slope is 2.1. This means that each kilometer costs $2.10.
The other statements are incorrect. The slope is not 5, so each kilometer does not cost $5. The y-intercept is not 5, so the ride does not last 5 kilometers. The y-intercept is the value of the function when the input is 0, which in this case is the initial fee of $2.10.

Answer:
Step-by-step explanation:
Let's start by finding the sum of the list of nine numbers, which we can then use to find the value of the remaining two numbers in the list:
Sum of the nine numbers = mean * number of numbers = 17 * 9 = 153
Let the three modes be a, b, and c. Since they are modes, each of them must appear at least twice in the list.
Let's assume that the numbers in the list are arranged in non-decreasing order. Then we have:
a ≤ b ≤ c
Since a, b, and c are modes, each of them must appear at least twice in the list. We have three cases to consider:
Case 1: Each of a, b, and c appears exactly twice in the list.
In this case, the remaining three numbers in the list are:
x1 = a + 4
x2 = b + 1
x3 = c - 8
We know that x1, x2, and x3 are distinct and not modes of the list. Therefore, they must be among the six numbers in the list that are not equal to a, b, or c. Let's call these numbers d, e, and f, where:
d ≤ e ≤ f
Then we have:
a + b + c + x1 + x2 + x3 + d + e + f = 153
3(a + b + c) + 3(d + e + f) = 153 + x1 + x2 + x3
Since x1, x2, and x3 are distinct and not modes of the list, we have:
x1 > c
x2 > b
x3 < c
Therefore, we can write:
x1 = c + k1
x2 = b + k2
x3 = a + k3
where k1, k2, and k3 are positive integers.
Substituting these expressions into the equation above, we get:
3(a + b + c) + 3(d + e + f) = 153 + a + b + c + k1 + k2 + k3
Simplifying, we get:
2(a + b + c) + 3(d + e + f) = 153 + k1 + k2 + k3
Since k1, k2, and k3 are positive integers, the right-hand side of this equation is at least 3. Therefore, we have:
2(a + b + c) + 3(d + e + f) ≥ 156
We want to find the value of 3(a + b + c), so let's isolate this term:
3(a + b + c) = 2(a + b + c) + (a + b + c)
Since the left-hand side is three times the sum of a, b, and c, and the right-hand side involves the sum of a, b, c, d, e, and f, we need to express d, e, and f in terms of a, b, and c.
From the inequality a ≤ b ≤ c, we have:
a + k3 ≤ b + k2 ≤ c + k1
Adding 4 to the first inequality, we get:
a + k3 + 4 ≤ b + k2 + 4 ≤ c + k1 + 4
Adding -8 to the second inequality, we get:
a + k3 + 4 ≤ c + k1 - 4 ≤ b + k2
Therefore, we can choose d = a + k3 + 4, e = c + k1 - 4, and f = b + k2. Then

First we start with the formula for cylinders v=(pi)r(squared)h filled in Thats v=(3.14)(8 squared) (8) which brings us to the answer 1607.68 but you must round to the nearest tenth aka 1607.7
Answer:
The first option, V ≈ 1607.7 in²
Step-by-step explanation:
Find the volume of the given cylinder.
\(\begin{center}\framebox{\parbox{4cm}{\textbf{Volume of a Cylinder:}\\[2ex]The volume of a cylinder with radius $r$ and height $h$ is given by the formula:\\[2ex]\center{$V = \pi r^2 h$} \\ \\}}\end{center}\)
Given:
r = 8 in
h = 8 in
π = 3.14
Find:
V = ?? in³
\(\hrulefill\)
Now solving,
Substitute the given values into the formula:
=> V = (3.14)(8)²(8)
Using a calculator to simplify:
=> V = 1607.68 in²
Rounded to the nearest tenth:
∴ V ≈ 1607.7 in²
Thus, the first option is correct.

Stores often mark up items each year to cover inflation. Last year, a CD at Juan’s Tunes cost $12.95. This year, the cost was marked up 8%. The store also gave anyone who bought four CDs this year a 10% discount. Explain the steps to find the final cost for the four CDs this year.
Answers
Answer:Find the amount the store marked up the CDs by.
12.95 * .08 = 1.034 which rounds to 1.04
Add that to the former price.
12.95 + 1.04 = 13.99
Multiply by 4 to see how many 4 CDs cost.
13.99 * 4 = 55.96
Multiply by .1 to see how much the discount is.
55.96 * .1 = 5.596 which rounds to 5.60
Subtract the discount from the original price.
55.96 - 5.6 = 50.36
It costs $50.36 to buy four CDs this year.

Let s - speed in still water, c - speed of current.
We have the following equations:
2(s + c) = 9
2(s - c) = 4
Simplify:
s + c = 4.5
s - c = 2
Add up and solve for s:
2s = 4.5 + 2
2s = 6.5
s = 6.5/2
s = 3.25 mph
Find c:
