What will be the location of the y value of R' after using the translation rule (x + 4, y - 7), if the pre-image R is located at ( -17, -3)
The location of the y value of R' after using the translation rule is -10
What will be the location of the y value of R' after using the translation rule?The translation rule is given as:
(x + 4, y - 7)
The pre-image of R is located at (-17, -3)
Rewrite as
R = (-17, -3)
When the translation rule is applied, we have:
R' = (-17 + 4, -3 - 7)
Evaluate
R' = (-13, -10)

The coordinates of A and B are (3k, 8) and (k, -3) respectively. Given that the gradient of the line segment AB is 3, find the value of k.
Step-by-step explanation:
gradient = slope or several other words.
it describes how strongly a line (or tangent to a bent curve) is going up or down or ... if it is changing at all.
it is represented by the ratio
(y coordinate change / x coordinate change)
when going from one point on the line to another.
in our case, when going from A to B we have
x changes by -2k (from 3k to k).
y changes by -11 (from 8 to -3).
so, the gradient or slope is
-11/-2k = 3
11/2k = 3
11 = 3×2k = 6k
k = 11/6
A = (33/6, 8) = (11/2, 8)
B = (11/6, -3)

that level, he ended up at 650 feet below sea level.
What was the total distance that Mr. Carter traveled
from his boat to where he ended up?
Answer:
he traveled 900 feet
Step-by-step explanation:
250 + 650 = 900
Mr. Carter traveled a total distance of 900 feet from his boat to where he ended up.
Here, we have to find the total distance that Mr. Carter traveled from his boat to where he ended up, we need to calculate the sum of the distances above and below sea level.
The distance above sea level is 250 feet (his house boat's level), and the distance below sea level is 650 feet (where he ended up after jumping).
Total distance traveled = Distance above sea level + Distance below sea level
Total distance traveled = 250 feet + 650 feet
Total distance traveled = 900 feet
Mr. Carter traveled a total distance of 900 feet from his boat to where he ended up.

As a fundraiser for the Lax Team, they plans to sell tees with the school logo. The company ducing the fees charges $125 for the design and set up plus $5 per tee. The lax members will sell tees for $10 each. How many do they need to sell to break even? PLEASE HELP
The company must produce 25 t-shirts to break even.
Here, we are given that a company producing t-shirts charges $125 for the design and set up plus $5 per tee.
This means-
fixed cost of producing the t-shirts = $125
Variable cost of producing a t-shirt = $5
Let x be the number of t-shirts produced
Thus, the total cost of producing t-shirts will be-
Total cost = 125 + 5x
Further, the selling price of 1 t-shirt = $10
Thus, selling price of x t-shirts = $10x
Now, at the break even point, the profit is 0, this implies-
Selling price = cost price
⇒ 10x = 125 + 5x
10x - 5x = 125
5x = 125
x = 125/5
x = 25
Thus, the company must produce 25 t-shirts to break even.

B(4015) is the [tex]2008^{th[/tex]term of the sequence.
What is the sequence?
A sequence is an enumerated group of particulars in mathematics where reiterations are permitted and order is important. analogous to a set, it has members( also called rudiments, or terms). The length of the series is the number of rudiments( potentially horizonless). A list of particulars in a particular order, generally figures, is called a sequence.Since the mean of the first terms is, the sum of the first terms is n². Thus, the sum of the first 2007 terms is 2007² and the sum of the first 2008 terms is 2008² Hence, the 2008th term of the sequence is
2008² - 2007² = (2008 + 2007) (2008 - 2007) = 4015
Note that n² is the sum of the first n odd integers.
From inspection, we see that the sum of the sequence is n². We also notice that n² is the sum of the first n odd integers.
Because 4015 is the only odd integer, B is the answer.

A sidewalk that is 2 ft wide surrounds a rectangle that is 4 ft by 6 ft what's the area of the sidewalk in square feet
The area of a sidewalk that surrounds a rectangle of 4 ft by 6 ft is 56 ft²
The given situation can be depicted in the attached picture.
Recall the formula to calculate the area of a rectangle:
A = l ⨉ w
Where:
l = length
w = wide
In the attached picture, the area of the sidewalk is the one with green color.
Notice that:
Area of sidewalk = area of bigger rectangle – area of smaller rectangle
Parameters of the bigger rectangle:
l = 6 + 2 + 2 = 10 ft.
w = 4 + 2 + 2 = 8 ft.
Area of bigger rectangle = 10 x 8 = 80 ft²
Parameters of the smaller rectangle:
l = 6 ft.
w = 4 ft.
Area of bigger rectangle = 6 x 4 = 24 ft²

he first step in simplifying the expression: (1.8 x 10^5) - (2.6 x 10^3)
a
Addition and subtraction requires the terms to be "like terms" with the same power of the base 10, so you would need to change the second number to (0.026 x 10^5).
b
Addition and subtraction do not require any changes, so you would just subtract (2.6 - 1.8) and (10^(5-3))
c
Addition and subtraction do not require any changes, so you would just subtract (1.8 - 2.6) and (10^(5-3))
d
Addition and subtraction requires the terms to be "like terms" with the same power of the base 10, so you would need to change the second number to (2600 x 10^5).
Using scientific notation, the first step in simplifying the expression is given by:
a. Addition and subtraction requires the terms to be "like terms" with the same power of the base 10, so you would need to change the second number to (0.026 x 10^5).
What is scientific notation?A number in scientific notation is given by:
[tex]a \times 10^b[/tex]
With the base being [tex]a \in [1, 10)[/tex].
For two numbers in scientific notation to be added or subtracted, they need to have the same exponent, which removes options b and c.
Moving the second number for 10^3 to 10^5 would be equivalent to a multiplication by 100, hence we have to divide by 100 at the base, that is:
2.6 x 10^3 = (2.6/100) x 10^5 = 0.026 x 10^5.
Hence option a is correct.

2) Factorize A (x) and B (x).
3) Solve the equation A (x)= B(x)
4) Prove that B (X) -3 = 2x(4x+7) , then solve the equation B(x) =3
Answer:
1) -5x² + 13x + 6
2) B(x) =(4x + 1 )(2x + 3)
A(x) = (5x +2)(3-x)
Step-by-step explanation:
1) Expand the equation by using distributive property. Then simplify by combining the like terms.
A(x) = (3 -x)2² - (x -3)(7x+ 4) - 18 + 2x²
= (3 - x)4 - [x*7x + x*4 - 3*7x - 3*4] - 18 + 2x²
= 3*4 - x*4 - [7x² + 4x - 21x - 12] - 18 + 2x²
= 12 - 4x - 7x² - 4x + 21x + 12 - 18 + 2x²
= 2x² - 7x² -4x - 4x + 21x + 12 + 12 - 18
= -5x² + 13x + 6
B(x) = (3x + 2)² - (x - 1)²
Identities:
(a + b)² = a² + 2ab + b² ; Here a =3x & b = 2
(m -n)² = m² - 2mn + n² ; Here m = x & n = 1
2) B(x) = (3x)² + 2*3x*2 + 2² - [x² - 2*x*1 + 1]
= 9x² + 12x + 4 - [x² - 2x + 1]
= 9x² + 12x + 4 - x²+ 2x - 1
= 9x² - x² + 12x + 2x + 4 - 1
= 8x² + 14x +3
Product = 8*3 = 24
Sum = 14
Factors = 2 , 12 {2*12 = 24 & 2 +12= 14}

= (4x + 1 )(2x + 3)
A(x) = - 5x² + 13x + 6

Cameron's current service charge of $0.95 per song, and the new service charge of $0.89 per song and $12 fee for joining, gives;
Formula for finding the number of songs that makes the cost of both services the same is; 0.95•s = 12 + 0.89•sComputing the value of s that satisfies the above equation gives the number of songs at which the cost of both service is the same as 200 songs The interpretation is the the cost of either service is the same when 200 songs are downloadedHow can the equation that gives the required number of songs be found?To Formulate
The charges for songs on the current music service is, C1 = 0.95•s
The charges for the new download service is, C2 = 12 + 0.89•s
Where the $12 is the joining fee
When the cost is the same for both service, we have;
C1 = C2
Which gives;
0.95•s = 12 + 0.89•sThe equation to represent when the cost for both service is the same is therefore;
0.95•s = 12 + 0.89•s
Computing;
The number of songs that gives the same costs is therefore;
0.95•s = 12 + 0.89•s
12 = 0.95•s - 0.89•s = 0.06•s
s = 12 ÷ 0.06 = 200
The number of songs at which the cost of each option will be the same is s = 200 songsInterpreting the solution;
The interpretation is, the cost of songs downloaded on both service will be the same, when 200 songs are downloaded.

A) The unit prices are the same. B) The package of 50 paper plates has the lower unit price. C) The package of 80 paper plates has the lower unit price. D) The package of 50 paper plates has the higher unit price.
Answer:
A) The unit prices are the same.
Step-by-step explanation:
First convert dollars to cents to make the calculation easier
Package of 50 paper plates costs $2.50
$2.50 = 2.50 x 100 = 250¢
So the unit price, which is the price per paper plate = 250/50 = 5¢
Package of 80 paper plates costs $4.00
$4.00 = 4.00 x 100 = 400¢
So the unit price, which is the price per paper plate = 400/80 = 5¢
So the unit prices of both packages are the same
