Answer:
A
Step-by-step explanation:
Adding positively to an x moves it right, and negative moves left. Adding to a y moves it up, and subtracting moves it down.
The transformation that moves figures to the right 3 units and down 7 units is A. (x, y) ⇒ (x + 3, y - 7)
Transformation is the movement of a point from its initial location to a new location. Types of transformation are rotation, reflection, translation and dilation.
Translation is the movement of a point up, down, right or left in the coordinate plane. If a point A(x, y) is moved a units right and b units down, the new location would be at A(x + a, y - b).
A function that moves figures to the right 3 units and down 7 units can be represented by:
(x, y) ⇒ (x + 3, y - 7)

To rent a certain vehicle, Rent-A-Ride charges $55.00 per day with unlimited miles. The cost of renting a similar vehicle at We Got Wheels is $38.00 per day plus $0.20 per mile. For what number of miles is the cost at Rent-A-Ride less than the cost at We Got Wheels?
Given :
Rent-A-Ride charges $55.00 per day with unlimited miles. The cost of renting a similar vehicle at We Got Wheels is $38.00 per day plus $0.20 per mile.
To Find :
For what number of miles is the cost at Rent-A-Ride less than the cost at We Got Wheels.
Solution :
Let, after x miles Rent-A-Ride charges is less than the cost at We Got Wheels.
Price at Got Wheels > Price at Rent-A-Ride
38 + 0.20x > 50
0.20x > 12
x > 60
Therefore, after 60 days cost at Rent-A-Ride less than the cost at We Got Wheels.
Hence, this is the required solution.
Let
f(x) = {3x - 7}/{x + 1] Find the range of f.
Give your answer as an interval.
Answer: Range = (-∞, 3) U (3, ∞)
Step-by-step explanation:
The range is the set of all y-values in a function. The easiest and most straightforward way to find the range is to graph the function and find asymptotes, or locations on the graph where the function lacks y-values.
You can plug in a few points to the equation, as shown in this table below.
After you have your points, you can draw your function following the points, as shown in the next image. Notice the line at y = 3, where the function does not cross. Although it will get infinitely close to the line, the function will never meet or cross this point at any x-value. This is what is known as a "horizontal asymptote", and is not included in the range of the function.
We can represent this asymptote in a range, which is a representation of all possible y-values in the function. The possible y-values for this function start at negative infinity and end at infinity, but do not exist at y = 3, so we represent this through this mathematical expression:
Range = (-∞, 3) U (3, ∞)

Which graph shows the function f(x) = x with an input of f(x – 3)? A coordinate plane with a line graphed passing through (negative 4, negative 1), (negative 3, 0), and (0, 3). A coordinate plane with a line graphed passing through (negative 1, negative 4), (0, negative 3), and (3, 0). A coordinate plane with a line graphed passing through (negative 1, negative 3), (0, 0), and (1, 3). A coordinate plane with a line graphed passing through (negative 3, negative 1), (0, 0), and (3, 1).
The given function, f(x) = x, and the function with an input of f(x - 3), which is a transformation of the function f(x), moving it three places to the right, gives the points on the graph of the function as the option;
(negative 1, negative 4), (0, negative 3), (3, 0)
What is the transformation of a function?The transformation of a function involves moving the curve or line that represents the function either left, right, down, or up, reflect the graph or compress or expand the curve of the graph of the function.
The given graph is for the function is f(x) = x, the required graph is the graph of the function, f(x - 3), which is evaluated as follows;
Given f(x) = x, we have, f(x - 3) = x - 3
The table of values for both functions is presented as follows:
x; -4, -3, -2, -1, 0, [tex]{}[/tex]1, 2, 3, 4, 5

For every 15 students who run track, there are 7 students who play baseball. There are 112 more students who run track than play baseball. How many students run track? How many students play baseball? Select your answers from the drop-down lists.
Answer:
210 students run track and 98 students play baseball
Step-by-step explanation:
For every 15 students who run track there are 7 students who play baseball
There are 112 more students who run track than play baseball
Let y represent the various groups of students
15 × y= 15y
7 × y= 7y
15y - 7y = 112
8y = 112
Divide both side by the coefficient of y which is 8
8y/8 = 112/8
y= 14
Therefore the number of students that run track is
= 15 × 14
= 210
The number of student that play baseball is
= 7 × 14
= 98
Hence 210 students run track and 98 students play baseball

Maureen, Frank, Tashia, Zane, Eric, and Wesley are addressing envelopes for volunteer work at a local charity. They were given ¾ of an entire mailing to address to be evenly divided among six of them. What fraction of the entire mailing does each person address?
Answer:
The fraction of the entire mail each person address = 1/8
Step-by-step explanation:
Given that:
number of people addressing envelopes = 6
If they gave out 3/4 of an entire mailing address.
Then, the amount of mailing not addressed is:
= 1 - 3/4
= [tex]\dfrac{4-3}{4}[/tex]
= 1/4
If 6 people shared 3/4 of an entire mailing to address evenly.
Then: each person gets:
[tex]=\dfrac{3}{4} \div 6[/tex]
[tex]=\dfrac{3}{4} \times \dfrac{1}{ 6}[/tex]
= 1/8
The fraction of the entire mail each person address = 1/8

Ralph drove 272 miles in 4 hours. What was his average
speed? (per single hour – unit rate)PLEASE HELP MEE
answer: 68
work:
all you basically do is just divide 272 by 4
If Ralph drove 272 miles in 4 hours then 68 miles per hour is the average speed
What is Division?
A division is a process of splitting a specific amount into equal parts.
Given that Ralph drove 272 miles in 4 hours
We need to find his average speed
The speed of an object is the magnitude of the change of its position over time or the magnitude of the change of its position per unit of time
Speed=Distance/ Time
Average speed=272/4
=68 miles per hour
Hence, if Ralph drove 272 miles in 4 hours then 68 miles per hour is the average speed

of the deluxe electric guitar? Find your solution below. Type the code in exactly.
(ALL CAPS, NO SPACES). Example: If my answer was -76.1 l would type in KHGLB
Answer:
It costs $795
Step-by-step explanation:
$30 more than one half so you have to subtract 30 from 295 then that's 265 which is 1/3 of the acual price. So then you have to multiply 265 by 3 then you get $795.

given g(x)=0.5x^2-5x+3.5, find g (4a)
Answer:
g(4a) = 8a^2 -20a +3.5
Step-by-step explanation:
Put 4a where x is and simplify.
g(x) = 0.5x^2 -5x +3.5
g(4a) = 0.5(4a)^2 -5(4a) +3.5
= 0.5(16a^2) -20a +3.5
g(4a) = 8a^2 -20a +3.5
