After swimming 80 feet below the surface of the water, a whale swims up 40 feet. Use a number line to help you create an equation that shows the new location of the whale in relation to the water's surface.
A) The equation is -80 + (-40) = -120. The whale is 120 ft below the water's surface.
B) The equation is -80 + 40 = -40. The whale is 40 ft below the water's surface.
C) The equation is -80 + (-40) = -40. The whale is 40 ft below the water's surface.
D) The equation is -80 + 40 = -120. The whale is 120 ft below the water's surface.
Answer:
the answer is d
Step-by-step explanation:
he swims 80 feet below so thats gonna be a negative number. he then swims up 40 feet so you would be adding . so -80+ 40 = -120
The new location of the whale in relation to the equation of water's surface is -80 + 40 = -120 which correct option (D)
What is equation?
Equation is the defined as mathematical statements that have a minimum of two terms containing variables or numbers are equal.
Whale swims 80 ft below so it be a negative number.
Whale then swims up 40 ft so would be adding .
When the whale is 120 ft below the water's surface so it be a negative number.
-80+ 40 = -120
Hence, the new location of the whale in relation to the equation of water's surface is -80 + 40 = -120

6.Find the value of x. Don't forget your reasons.
(x-38)
Answer:
x = 109
Step-by-step explanation:
The figure has one pair of parallel sides and is a trapezoid.
The lower base angle is supplementary to the upper base angle on the same side, thus
x + x - 38 = 180 , that is
2x - 38 = 180 ( add 38 to both sides )
2x = 218 ( divide both sides by 2 )
x = 109
Suppose that a number written as a decimal has an infinite number of non-repeating digits after the decimal point. What is this number called?
Oirational
natural
unnatural
rational
Hell yall
Answer:
Irrational
Step-by-step explanation:
The number is called an irrational number.
These numbers have some distinct properties. The number of numbers after the decimal point is infinite. What this means is that it does not terminate. It keeps on repeating.
Also, these numbers cannot be represented as a ratio of two integers i.e two whole numbers. This is because they keep on going without termination.
Lastly is that these numbers do not repeat after decimal. What I mean by this is that they do not keep repeating a particular number after the decimal point. For example in cases like 2.33333; these are infinite too, but they can be represented by the ratio of two whole numbers and in such cases, they are not irrational in their own respect

as written there, they are not inverses
proof by counter example: since g(1) = 3 , but g^-1(3) = -5/3 != 1
Step-by-step explanation:
g(g^-1(x)) == x if they are indeed inverses
1/(1/x -2) + 2 = x/(1-2x) + 2 != x so, they are not inverses

find the value of x !
Answer:
x = 32
Step-by-step explanation:
So we are given the measures of two of the three interior angles. 98° and 50°. We are also given that the value of the third interior angle is equal to x°. Remember, the sum of the interior angles of a triangle is 180°. Knowing this, we can make the equation:
x + 98 + 50 = 180
Now we solve for x. Subtract 50 from both sides.
x + 98 = 130
Subtract 98 from both sides.
x = 32
So the value of x is 32.

In June, Clarissa used 115 gigabytes of data on her cell phone. Given that June has 30 days, how much data did she use on average per day?
Answer:
She used an average of (115/30) gigabytes of data per day
Step-by-step explanation:
To get the average data usage per day, we simply divide the total data used by the number of days
Mathematically, that will be
115 gigabytes/ 30 days = 3.83 gigabytes per day

Fiona is completing the square to solve the polynomial
equation.
What should be her first step?
x2 - 4x + 1 = 0
isolating the constant 1
O adding 4 to both sides of the equation
O isolating the second term, 4x
adding 1 to both sides of the equation
Answer:
isolating the constant 1
Step-by-step explanation:
The first step in solving the equation via completing the square is to isolate the constant.
What is completing the square method?The term completing the square method refers to one of the popular methods of solving quadratic equations that involves the addition of half of the square of the b term to both sides of the equation.
Given that an equation, x²-4x+1 = 0, we need to find the first step to solve this be using completing the square method,
So, according to the definition, we will add first isolate the constant,
Therefore,
x²-4x+1 = 0
x²-4x = -1
Now, we will add 4 to both the side,
x²-4x+4 = -1+4
(x+2)² = 3
x+2 = ±√3
x = √3-2 or x = -√3-2
Hence, the first step in solving the equation via completing the square is to isolate the constant.

Your answer is going to be c The graph ofg(x)is the graph of f(x) translated 1 unit down.
Step-by-step explanation:
I just took the k12 4.08 quiz
The graph of g(x)is the graph of f(x) translated 1 unit down. Therefore, option C is the correct answer.
We need to find the relationship between the graph of f(x) and the graph of g(x)=f(x)−1.
What is the translation?A translation moves a shape up, down or from side to side but it does not change its appearance in any other way.
Translation Rules:
When the shape is moved towards the left by k units, then replace x with x - k.When the shape is moved towards the right by k units, then replace x with x + k.When the shape is moved up by k units, then replace y with y + k.When the shape is moved down by k units, then replace y with y - k.From the translation rule, g(x)=f(x)−1 is f(x) translated 1 unit down.
The graph of g(x)is the graph of f(x) translated 1 unit down. Therefore, option C is the correct answer.
