-2(v- 2) =-3 -22
What’s the answer?
Answer:
v= 29/2
Step-by-step explanation:
Step 1: Simplify both sides of the equation.
−2(v−2)=−3−22
(−2)(v)+(−2)(−2)=−3+−22(Distribute)
−2v+4=−3+−22
−2v+4=(−3+−22)(Combine Like Terms)
−2v+4=−25
−2v+4=−25
Step 2: Subtract 4 from both sides.
−2v+4−4=−25−4
−2v=−29
Step 3: Divide both sides by -2.
−2v
−2
=
−29

v=

A bucket has a leak that started 6 hours ago. At time 0, when the bucket just emptied, a tap was turned on for 3 hours. The amount of water in the bucket can be modeled by the function f(x) = |x| over the interval [−6, 3], where x is the time, in hours, and y is the amount of water in the bucket, in gallons. Which translation of the graph represents the last 3 hours of the leak, and the tap running for 6 hours? Group of answer choices g(x) = |x − 3| g(x) = |x| + 3 g(x) = |x| − 3 g(x) = |x + 3|
Answer:
The answer is g(x) = |x - 3|
Step-by-step explanation:
Here we have a general problem of horizontal translations, we will see that the correct option is g(x) = |x - 3|
We know that the bucket was leaking for 6 hours, and then it was filled in 3 hours.
Then in the interval [-6, 0) the bucket was leaking
In the interval [0, 3] the bucket was being filled.
Now we want a transformation that represents the last 3 hours of leaking.
Also, remember that for a general function f(x), an horizontal translation of N units is written as:
g(x) = f(x + N)
If N is positive, the translation is to the left
If N is negative, the translation is to the right.
If we want to represent the last 3 hours of leaking (which happen for negative values of x) then we need to move the whole graph to the right.
So, if we define the function as:
g(x) = f(x - 3)
when we evaluate g(x) in zero we get:
g(0) = f(-3)
So this new function, at the time zero, starts representing the last 3 hours of leaking of the bucket.
Remembering that f(x) = |x|
We can see that the correct option is:
g(x) = f(x - 3) = |x - 3|
g(x) = |x - 3|
Below you can see a graph with a comparison of f(x) and g(x), where the green one is f(x) and the blue one g(x).

Answer:
x = -1/3 - 3/2y
Step-by-step explanation:
Step 1: Write out equation
3y + 2x = -1
Step 2: Subtract 3y on both sides
3y - 3y + 2x = -1 - 3y
2x = -1 - 3y
Step 3: Divide both sides by 2

imagine an investigation in which 40 students were asked to determine their chronotype by choosing from among four chronotypes instead of three: morning person, night person, neither, or both. If there is no relationship between chronotype and birth month, about what fraction of the students would you expect to pick the chronotype that matches their birth month? why do you think this?
Step-by-step explanation:
A chronotype is a behavioral manifestation of an underlying circadian rhythms of the myriad physical processes.
The chronotype word may be defined as an individual's natural tendency to remain active mostly at certain times of the day. Some people remain active and alert in the early time of the day and some are alert and active in the late night.
The chronotypes are : Morning person, night person, neither/both.
It is assume that the birth month and year of a person influences his or her chronotype. But if birth month is not related to theses personality traits of a person, then it can be expected that nearly 1/3rd of the fraction of the students in class picks the chronotype which corresponds to their birth type.

-2.75 is classified as?Select all that apply Natural Number Whole Number Integer Rational Number
Answer:
Rational Number
Step-by-step explanation:
It is not a natural number as natural numbers are the counting numbers we use and therefore only encompass positive integers,which - 2.75 is not. Whole numbers and integers do not include decimals and fractions, therefore - 2.75 is not included either does to its decimal. Finally it is a rational number because it can be properly expressed as a fraction (-2.75/1). Therefore it is just a rational number from this list.

You are building a shelf that fits in a corner in the figure the entire shelf is XYZ each unit in the coordinate plane represents one inch find the area a of the shelf X is (15,20) Z is (0,5) Y is (15,5)
Answer:
[tex]Area = 112.5[/tex]
Step-by-step explanation:
Given
[tex]X = (15,20)[/tex]
[tex]Y = (15,5)[/tex]
[tex]Z = (0,5)[/tex]
Required
Determine the area of the triangle
The area is calculated using the following formula:
[tex]Area = |\frac{X_x(Y_y - Z_y) + Y_x(X_y - Z_y) + Z_x(X_y - Y_y)}{2}|[/tex]
Where
[tex](X_x,X_y) = (15,20)[/tex]
[tex](Y_x,Y_y) = (15,5)[/tex]
[tex](Z_x,Z_y)= (0,5)[/tex]
Substitute right values in the given formula:
[tex]Area = |\frac{15(5 -5) + 15(20 - 5) + 0(20 - 5)}{2}|[/tex]
[tex]Area = |\frac{15(0) + 15(15) + 0(15)}{2}|[/tex]
[tex]Area = |\frac{0 + 225 + 0}{2}|[/tex]
[tex]Area = |\frac{225}{2}|[/tex]
[tex]Area = |112.5|[/tex]
[tex]Area = 112.5[/tex]
Hence, the area of the triangle is 112.5

If you can't use a calculator break it apart.
1 X 3.24 is 3.24
Now take .2 x 3.24 this is easy, just remember to move the decimal in the answer one more to the left.
3.24

Step-by-step explanation:
Hey there!
Simply work with it.
As it is a Right angled triangle, taking angle 40° as a reference angle. Then,
Length of board = hypotenuse = 15 feet.
To find: height of ladder = perpendicular.
Now,
Taking sin ratio,
[tex] \sin = \frac{p}{h} [/tex]
[tex]sin \: 40 = \frac{p}{15} [/tex]
or, as in per the given sin value is 0.6428
so,
[tex]0.6428 = \frac{p}{15} [/tex]
or, 15 × 0.6428 = p
or, p = height of ladder = 9.642.
Therefore, p = height of ladder = 10 feet. { rounding off we get 10 feet as answer}.

Consider the following 8 numbers, where one labelled x is unknown. 42, 47, 5, x , 18, 12, 50, 1 Given that the range of the numbers is 59, work out 2 values of x .
===========================================================
Explanation:
Let's assume that x is the largest value of the list. If so then x = 60 because
range = max - min
range = x - 1
range = 60-1
range = 59
Effectively, you work backwards to go from a range of 59 to have x = 60 as the max.
So x = 60 is one possible value. We can't have x any larger or the range would be larger.
But we can have x be smaller. Specifically, it would be the min of the list. If negative x values are allowed, then x = -9 is the other possible x value
Here's why
range = max - min
range = 50 - x
range = 50 - (-9)
range = 50+9
range = 59
Which of the following is a quantitative variable?
Temperatures in New York from January to March

Population density of a town
Symbols of elements on the periodic table
Answers: A, B, C
These three deal with numeric values, so that is why they are quantitative variables. Think quantitative as quantity to help remember.
In contrast, choice D is a qualitative variable. Instead of dealing with numbers, it deals with symbols or labels. You could also call this a categorical variable (each label being its own category).
the slope-intercept form of an equation is y = mx + b. rewrite the equation in terms of the slope m
Answer:
[tex]\displaystyle m=\frac{y-b}{x}[/tex]
Step-by-step explanation:
We are given the equation:
[tex]y=mx+b[/tex]
And we want to rewrite it in terms of m.
We can subtract b from both sides:
[tex]y-b=mx[/tex]
Finally, dividing both sides by x yields:
[tex]\displaystyle m=\frac{y-b}{x}[/tex]
In conclusion:
[tex]\displaystyle m=\frac{y-b}{x}[/tex]
Given the equation, 5x + 10y = 20, what are your x and y-intercepts? Explain your thought process and steps in your reply.
Answers:
x intercept = 4
y intercept = 2
============================================
Explanation:
To find the x intercept, plug in y = 0 and solve for x
5x+10y = 20
5x+10(0) = 20
5x = 20
x = 20/5
x = 4
The x intercept is x = 4, which means it is located at the point (4,0)
-----------------------
We'll flip things around for the y intercept. Plug in x = 0 and solve for y to get the y intercept.
5x+10y = 20
5(0)+10y = 20
10y = 20
y = 20/10
y = 2
The y intercept is located at (0,2), but we can just say "the y intercept is 2" as an alternative.
