What is the independence and dependent variable? Also label the (x) and (y) axis.
Answers
Answer:
The Independent Variable is the variable or thing that depends on nothing, nothing can affect it, nor can it be changed by any other variables, in this case the Independent variable is the Fish tank, the fish tank depends on nothing, and will stay the same.
The Dependent Variable is the variable or thing that depends on one or more variables in the equation, it be changed by any other variables, in this case the dependent variable is the fish, the fish depend on the water in the tank.

Step-by-step explanation:
5n+6+(-7n)

5n-7n+6
-2n+6
Hope this helps ;) ❤❤❤
Answer:
-2n + 6
Step-by-step explanation:
Combine like terms (terms with the same amount of variables).
Note the laws of signs:
Two additions signs: If there are two addition signs directly next to each other (which will not be shown very much), it means to add.
One addition sign & One negative sign: If there is one of each signs directly next to each other (as shown here), you must default it to negative and subtract.
Two negative signs: If there are two negative signs directly next to each other, you must default it to positive and add.
First, change the expression to signify how you should combine the terms:
5n + 6 + (-7n) = 5n - 7n + 6
Combine like terms:
(5n - 7n) + 6
-2n + 6
-2n + 6 is your answer.

A triangle has coordinates of A(1, 2), B(4, 6), and C(4, -3).
1. If the triangle is translated 2 units right, what are the new coordinates?
2. If ΔABC is reflected over the x-axis, what are the new coordinates?
Please show all work and not just the answer.
Answers
1 = (3,2) B= (6, 6) C = (6, -3)
Move two to the right since left and right deals with the x axis, add two to the x’s
2 = (1, -2) B = (4, -6) C = (4, 3)
Reflecting across the x axis means the formula is (x, -y) so switch the sign of the y’s
Answer:
1) A (3,2), B (6,6), C (6,-3)
2) A (1,-2), B (4,-6), C (4,3)
Step-by-step explanation:
1) Each of the x-values goes up two.
A (1,2) becomes (3,2)
B (4,6) becomes (6,6)
C (4,-3) becomes (6,-3)
2). I assume they mean the ORIGINAL ABC, not the one you just translated 2 units to the right.
To do this, you just multiply each y-value times negative one.
A (1,2) becomes (1,-2)
B (4,6) becomes (4,-6)
C (4,-3) becomes (4,3)

the distance a jet travels varies directly as the number of hours it flies. A jet traveled 2875 miles in 5 hours. What is the constant of variation
Answers
Answer:
k = 575
Step-by-step explanation:
let d be distance and h time.
Given d varies directly as h then the equation relating them is
d = kh ← k is the constant of variation
To find k use the condition d = 2875, h = 5, then
2875 = 5k ( divide both sides by 5 )
k = 575

a patio in the shape of a rectangle, is fenced on all sides with 134 feet of fencing. the patio is 5 feet less wide than its long. what is the area of the patio?
Answers
Answer:
The area of the patio is 1,116 ft^2
Step-by-step explanation:
Here in this question, we are interested in calculating the area of the patio.
Mathematically, area of patio is;
length * width
Unfortunately we do not have these values. Thus we need to get this from the value of the perimeter of the fencing and the relationship between the width and the length.
Mathematically, the total length of the fencing is the perimeter of the fencing.
Now, we are also told that the patio is 5 feet less wide than it is long.
So if the length is x ft, the width is (x-5) ft
Mathematically;
the perimeter of a rectangle is;
2(l + b)
Writing this in the x terms and equating to the perimeter, we have;
2( x + x -5) = 134
divide through by 2
2x -5 = 67
2x = 67 + 5
2x = 72
x = 72/2
x = 36 ft
Thus since the length is 36 ft, the width would be x -5 = 36 -5 = 31 ft
Done? No!
The question asks to calculate the area. Let’s move these values to the initial equation of the area in the start of the question.
Thus, we have 31 * 36 = 1,116 ft^2

Give an odd function which of following transformations would result in an odd function
Answers
Answer: Reflection across the x-axis and Vertical stretch are the ones that return an odd function.
Step-by-step explanation:
An odd function f(x) is a function such that:
f(-x) = -f(x).
So let's analyze the options:
A) Horizontal translation.
An horizontal translation of A units to the right (A > 0) is written as:
g(x) = f(x - A)
Now, let's see if g(x) is also odd.
g(x) = f(x - A)
g(-x) = f(-x - A)
Now, f(-x - A) is equal to -f( x + A)
then:
g(-x) = f(-x - A) ≠ -g(x) = -f(x - A)
This is not an odd function.
B) Reflection over the x-axis.
When we have a point (x, y), a reflection over the x-axis changes the sign of the y-variable.
Then we have that:
g(x) = -f(x).
Then:
g(x) = -f(x)
g(-x) = -f(-x) = -(-f(x)) = f(x)
then:
g(x) = -f(x) = -g(-x)
This is an odd function.
C) Vertical stretch:
We can write a vertical stretch of factor scale A as:
g(x) = A*f(x).
Let's see if g(x) is odd:
g(-x) = A*f(-x) = A*(-f(x)) = -A*f(x) = -g(x)
this is a odd function.
C) Vertical translation:
A vertical translation of A units up (A > 0) is written as:
g(x) = f(x) + A.
Similar to the case of the horizontal translation, so it is easy to see that g(x) is not an odd function.
