Answers
In general, a translation:
• in the x-direction by n units is given by: (x, y) → (x + n, y),
,• in the y-direction by m units is given by: (x, y) → (x, y + m),
,• the combination of both translations is: (x, y) → (x + n, y + m).
In this problem, we want to translate a triangle 2 units up and 5 units to the right, so we want to translate the points of the triangle in the following way:
[tex](x,y)\rightarrow(x+5,y+2)[/tex]From the graph we see that the coordinates of point A are:
[tex](x_A,y_A)=(-1,2)[/tex]Making the translation we get:
[tex](x_A+5,y_A+2)=(-1+5,2+2)=(4,4)[/tex]Answer

In centrally planned economies, the distribution of goods costs nothing to administer
Answers
The following statement "In centrally planned economies, the distribution of goods costs nothing to administer" is true.
A centrally planned economy, often known as a command economy, is an economic system in which a government agency makes economic choices affecting the production and distribution of products. Centrally planned economies vary from market economies in that these decisions are the outcome of hundreds of choices made by producers and consumers.
State-owned corporations provide goods and services in planned economies, however, independent firms may occasionally be brought into economic planning. Prices, salaries, and production schedules are often set by a centralized bureaucracy.

Veronika has 3 daughters. Today the eldest is 7 years older the the second who is 2 years older than the youngest. The sum of their ages 12 years from now will be 56. How old are they today?
Answers
We define the following variables:
• x = age (in years) of the eldest,
,• y = age (in years) of the second,
,• z = age (in years) of the youngest.
From the statement, we know that:
0. the eldest is 7 years older than the second → , x = 7 + y,,
,1. the second is 2 older than the youngest → ,y = 2 + z,,
,2. the sum of the ages 12 years from now will be 56 → x + y + z + 12 = 56 → ,x + y + z = 56 - 12 = 44,.
We have the following system of equations:
[tex]\begin{gathered} x=7+y, \\ y=2+z, \\ x+y+z=44. \end{gathered}[/tex]i) Replacing the second equation in the first one, we have:
[tex]x=7+y=7+(2+z)=9+z\text{.}[/tex]ii) Summing the ages of the three daughters, we have:
[tex]x+y+z=(9+z)+(2+z)+z=11+3z\text{.}[/tex]iii) Equalling the last equation with the third one, we have:
[tex]\begin{gathered} 11+3z=44, \\ 3z=44-11=33, \\ z=\frac{33}{3}=11. \end{gathered}[/tex]Replacing the value of z in the equation of x and y, we get:

Solve 6x+3y=−1 for y
Answers
The required solution of the given equation 6x + 3y = −1 for y would be the value of equation y = -2x - 1/3.
What is the equation?The term "equation" refers to mathematical statements that have at least two terms with variables or integers that are equal.
The equation is given in the question below as:
6x + 3y = −1
We have to determine the solution of the equation 6x + 3y = −1 for y.
⇒ 6x + 3y = −1
Rearrange the terms of the variable in the above equation,
3y = - 6x - 1
Divided by 3 both sides of the equation to get
y = -2x - 1/3
Hence, the required solution of the given equation 6x + 3y = −1 for y would be the value of equation y = -2x - 1/3.

Write a system of equations to describe the situation below, solve using substitution, and fill in the blanks.Vince is comparing the cost of a fresh lobster dinner at two different restaurants. The first restaurant charges $51 for the meal, plus $5 per kilogram for the lobster he picks. At the second restaurant, Vince would pay $8 per kilogram for the lobster, in addition to $33 for the meal. Vince realizes that, in theory, dinner at both restaurants could cost the same amount if the lobster had a certain weight. How much would Vince pay for his dinner? What is the weight?Dinner would cost $ at either restaurant if Vince's lobster weighed kilograms.
Answers
Based on the given situation, if x is number of kilograms of lobster, you can write the following expressions:
51 + 5x cost in the first restaurant
33 + 8x cost in the second restaurant
In order to determine the value of x which makes the cost the same in both restaurants, equal the previous expressions and solve for x:
51 + 5x = 33 + 8x subtract 33 both sides and 5x subtract both sides
51 - 33 = 8x - 5x simplify
18 = 3x divide by 3 both sides
18/3 = x
6 = x
x = 6
Hence, the weight of the lobster is 6 kg.
The cost of the dinner is:
51 + 5(6) = 51 + 30 = 81
Hence, the cost of the dinner is $81

Answers
Answer:
48/13
Step-by-step explanation:
To make this into an improper fraction, convert the integer into a fraction using the denominator of the fraction
3 * 13/13 = 39/13
Then add it to the rest of the fraction
39/13 + 9/13
= 48/13
Answer: 48/13
Step-by-step explanation: first multiply 3 x 13 to get 39. do this because you get the fraction for the whole number, 3. then, add 39 to the numerator (9). you will get 48/13. you do this because you are adding the whole number (3) to the fraction so that way it is an improper fraction.

y = 2x − 8
y = 2x + 8
y = −2x + 4
y = −2x − 4
Answers
Answer: y = 2x - 8
Step-by-step explanation:
When x = 0, y = -8. This is the y-intercept.
As x increases by 1, y increases by 2. This makes 2 the slope.
The equation for the linear relationship given, in slope-intercept form is y = 2x-8
What is slope-intercept form?The slope-intercept form of a linear equation is where one side contains just "y". So, it will look like: y = mx + b where "m" and "b" are numbers.
Given that, coordinates representing a linear relationship.
x → 0, 1, 3, 4
y → -8, -6, -2, 0
We need to find an equation for the given linear relationship in slope-intercept form,
Considering points, (0, -8) and (4, 0)
We know that, the equation of a line passing through, two points is given by,
y-y₁ = (y₂-y₁) / (x₂-x₁) (x-x₁)
Here, y₁ = -8, y₂ = 0, x₁ = 0, x₂ = 4
Therefore, the equation is =
y+8 = 8/4(x-0)
y+8 = 2x
y = 2x-8
Hence, the equation for the linear relationship given, in slope-intercept form is y = 2x-8

A traffic study has shown that the probability that 5 cars will pass over a small bridge in a 4-minute period is 0.16.What are the odds against exactly 5 cars passing over the bridge in that time?
Answers
A probability is the number of outcomes divided by the number of total outcomes.
An odd is given by a:b, in which a is the number of successes and b is the number of failures.
From the question, the probability of 5 cars will pass over a small bridge is 0.16
That means the total outcomes is 100 and the outcomes of successes are 16
Then to find the failures subtract 16 from 100
The failures = 100 - 16 = 84
Successes = 16
a = 16
Failures = 84
b = 84
Odds = a: b
Odds = 16: 84
Divide each term by 4 to simplify
Odds = (16/4): (84/4)
Odds = 4: 21
The answer is 4: 21

For the following, find f(2.1) and f(4).
Answers
Answer:
A
Step-by-step explanation:
Comment
The tricky part is f(4)
Log part
That is defined by log_2 which means that the base used for the log is 2.
We don't have log_2 on our calculators so you have to create it.
Substitute 4 for x
log_2 (4) = log_10(4)/ log_10 (2) Which your calculator can handle
log_2 (4) = Log(4)/ log(2) = 2
f(x) = 1/2 x^2
x = 2.1
Only answers a and b are correct, but which one is right? 2.1 is between 2 and 4. So you choose f(x) = 1/2 x^2
1/2 2.1^2 = 1/2 4.41 = 2.205
Answer
A
Answer:
(a) f(2.1) = 2.205 and f(4) = 2
Step-by-step explanation:
You want to evaluate a piecewise-defined function to find f(2.1) and f(4).
DomainThe first step in evaluating a piecewise defined function is to match the argument value with the appropriate domain.
for f(2.1), you want to use the definition for the domain 2 < x < 4for f(4), you want to use the definition for the domain 4 ≤ x < 8Function evaluationOnce you have identified the function you are evaluating, substitute the argument for the variable and carry out the arithmetic in the usual way.
f(2.1) = 1/2(2.1)² = 1/2(4.41) = 2.205f(4) = log₂(4) = log₂(2²) = 2The desired function values are f(2.1) = 2.205 and f(4) = 2.
