Answer: x' = x - 2yd.
Step-by-step explanation:
When we have a function:
y = g(x)
A translation to the east (in this case the positive x-axis) of N units.
is written as:
y = h(x) = g(x - N)
then if in the beginning our variable was x, afther the translation the variable will be x - N.
Now in this case we have a translation of 2yd to the right (to the east)
Then our new variable, let's call it x', will be:
x' = x - 2yd.
Answer:
A translation of two yards east involves moving 2 units in the positive x-direction. Given any initial x-coordinate, x, the algebraic expression that represents the new x-coordinate after the translation is x + 2.

Rectangle PQRS has vertices at P-2,5), Q44,5), R(4, -1), and S(-2,-1). What is the area, in square units, of rectangle PQRS? 21 b 35 36 40
Answer:
36 square units.
C
Step-by-step explanation:
Please refer to the provided graph.
So we want to figure out the area of the rectangle. To do so, we simply need to figure out the base and height of the rectangle. We can then multiply them together to acquire the area.
From the graph, we can see that if we find the length of SR and SP, we can use the the base and height, respectively.
Now, we just have to find there lengths. Technically, we could just count. However, I'm going to use the distance formula.
the distance formula is:
[tex]d=\sqrt{(x_2-x_1)^2+(y_2-y_1)^2}[/tex]
Find the length of SR:
Point S is (-2,-1) while Point R is (4,-1). Let (-2,-1) be x₁ and y₁ and (4,-1) be x₂ and y₂. Therefore:
[tex]d=\sqrt{(4-(-2))^2+(-1-(-1))^2}\\d=\sqrt{(6^2)+(0)^2} \\d=\sqrt{36}=6[/tex]
So, SR is 6.
Now, find the length of SP:
Point S is (-2,-1) while Point P is (-2,5). Let Let (-2,-1) be x₁ and y₁ and (-2,5) be x₂ and y₂. Therefore:
[tex]d=\sqrt{(-2-(-2))^2+(5-(-1))^2}\\d=\sqrt{0^2+6^2}\\ d=\sqrt{36}=6[/tex]
Therefore, SP is also 6.
Now, the area for a rectangle is:
[tex]A=bh[/tex]
Plug in 6 for the base and 6 for the height:
[tex]A=6(6)\\A=36\text{ units}^2[/tex]

Melissa was charged $3 each time she
used the ATM at work. She used the
work ATM 24 times in a month. By how
much did her bank account change from
using the ATM at work?
Answer:
Therefore, Melissa will be charged $72 for busing work ATM 24 times in a month
Step-by-step explanation:
Melissa was charged $3 each time she used the ATM at work
She used the work ATM 24 times in a month.
Charge per usage= $3
Number of times of usage= 24
By how much did her bank account change from using the ATM at work
Total charges = charge per usage × Number of times of usage
= 3 × 24
= 72
Total charges = $72
Therefore, Melissa will be charged $72 for busing work ATM 24 times in a month

Tickets for a concert cost $2 for children, $3 for students, and $4 for adults. Ticket sales totaled $522 and 177 people attended the concert. Twice as many students as adults attended. Find how many of each type of ticket were sold. Assume that everyone who bought a ticket attended the concert.
Answer:
Children = 51
Adults = 42
Students= 84
Step-by-step explanation:
Children = $2
Students = $3
Adults = $4
Total sales = $522
Total people who attended = 177
Adults =a
Students = s= 2a
Children = c
c+s+a = 177 (1)
2c+3s+4a=522 (2)
Substitute s=2a into the equations
c + 2a + a = 177
c + 3a = 177 (3)
2c + 3(2a) + 4a = 522
2c + 6a + 4a = 522
2c + 10a = 522 (4)
c + 3a = 177 (3)
2c + 10a = 522 (4)
Multiply (3) by 2
2c + 6a = 354 (3b)
2c + 10a = 522
Subtract (3b) from (4)
10a - 6a = 522 - 354
4a = 168
Divide both sides by 4
a= 168/4
= 42
a= 42
s= 2a
= 2(42)
= 84
s= 84
Substitute the value of s and a into (1)
c+s+a = 177 (1)
c + 84 + 42 = 177
c + 126 = 177
c = 177 - 126
= 51
c=51
Children = 51
Adults = 42
Students= 84
Find the volume for the following composite object.

( plz mark me as brainliest, that would be most appreciated! )
On a coordinate plane, a line goes through (negative 3, 2) and (2, negative 1). A point is at (3, 0). What is the equation of the line that is perpendicular to the given line and passes through the point (3, 0)? 3x + 5y = −9 3x + 5y = 9 5x − 3y = −15 5x − 3y = 15
Answer:
5x -3y = 15
Step-by-step explanation:
First find the slope of the line through ( -3,2) and (2,-1)
m = (y2-y1)/(x2-x1)
=( -1-2)/(2--3)
= -3/(2+3)
= -3/5
We want a line that is perpendicular so the slopes will multiply to -1
m * -3/5 = -1
Multiply each side by -5/3
m * -3/5 * -5/3 = -1 *-5/3
m = 5/3
The slope of the perpendicular line is 5/3
We have a slope and a point
Using point slope form
y-y1 = m(x-x1)
y-0 = 5/3( x-3)
y = 5/3( x-3)
Distribute
y = 5/3x -5
Multiply each side by 3
3*y = 3(5/3x -5)
3y = 5x - 15
Subtract 5x from each side
-5x+3y = -15
Multiply each side by -1
5x -3y = 15
Answer:
D. 5x − 3y = 15

The Distributive property states that when we have the statement a(b + c), we can "distribute" the a by multiplying a times both terms that are inside the parenthses.
So in this problem, 2(5 + 7) can be simplified by distributing the
2 through both terms that are inside the set of parenthses.
So we have (2 · 5) + (2 · 7).

Solve |2x - 5| = 4 I dont know what you solve for
Hello!
Answer:
[tex]\huge\boxed{x = 1/2, 9/2}[/tex]
|2x - 5| = 4
Solve for the negative and positive expressions:
2x - 5 = 4
2x = 9
x = 9/2

C. How do the processes you used for
parts A and B differ? How are they the same?
Answer:
Original Medicare comes in two parts. Medicare Part A covers hospital services, skilled nursing facility care, hospice, and some home health care. Medicare Part B covers medical services, including doctor visits, preventive screenings, certain vaccinations, lab tests, and durable medical equipment.
Bottle A can hold 3L more juice than bottle B. Bottle D can hold 5L more juice than bottle A. Bottle C can hold 3L less juice than bottle A.
Answer:
This may be incomplete, i will try to answer this in a general way.
We have 4 bottles, A, B, C and D.
If A is the volume of Bottle A, B is the volume of bottle B, C is the volume of bottle C, and D is the volume of bottle D, we have that:
A = B + 3L.
D = A + 5L
C = A - 3L.
Let's solve this system the most we can (we can not fully solve the system because we have more variables than equations)
First, taking the third equation and adding 3L in both sides, we have:
C + 3L = A.
This is equivalent to the first equation, so we have that C = B.
now, we have two equations:
A = B + 3L
D = A + 5L
We can replace the first equation into the second equation and get:
D = A + 5L = (B + 3L) + 5L = B + 8L
So bottle D can hold 8L more juice than bottle B (and because bottle B and bottle C have the same volume, bottle D can hold 8L more juice than bottle C)
Now, we can order the bottles depending on the volume:
Bottle D is the one with larger volume.
Bottle A comes next.
Bottles C and B are the smaller ones, and they are together because they have the same volume.

How can I identify witch of those numbers don’t belong with the other there 50.1 -50 over two -50.1 square root of 50?
I'm assuming you were given these four values
50.1, -50/2, -50.1, sqrt(50)
where 'sqrt' stands for 'square root', and the slash symbol means divide or fraction.
If my assumption is correct, then the term that does not belong is sqrt(50). This is because the other values are all rational. We can express them as a fraction of two whole numbers
50.1 = 501/10-50/2 is already a fraction, no need to do any work for this one-50.1 = -501/10But we can't do the same with sqrt(50). It is irrational. Note how 50 is not a perfect square. Your calculator will show that sqrt(50) = 7.07106781186548 and that decimal sequence goes on forever without any pattern. If you were given sqrt(49), then it would work because sqrt(49) = 7 = 7/1.

11. Melissa is buying a sweater. The original cost of the sweater
is $18.00. The sweater is 15% off, and sales tax is 8%. How
much will the sweater cost?
a) $14.08
O b) $12.24
O c) $16.52
O d) $15.30
Answer:
Hey there!
The sweater is selling for 85% of the original price
0.85(18)=15.30
1.08(15.30)=16.52
Let me know if this helps :)
The solution is Option C.
The total cost of the sweater is $ 16.52
What is an Equation?
Equations are mathematical statements with two algebraic expressions flanking the equals (=) sign on either side.
It demonstrates the equality of the relationship between the expressions printed on the left and right sides.
Coefficients, variables, operators, constants, terms, expressions, and the equal to sign are some of the components of an equation. The "=" sign and terms on both sides must always be present when writing an equation.
Given data ,
Let the original cost of the sweater be = $ 18
Let the sales tax percentage be = 8 %
Let the discount of the sweater be = 15 %
So , the equation for the total cost of the sweater is
The cost of the sweater after discount of 15 % is = original cost of the sweater - discount of the sweater x original cost
The cost of the sweater after discount of 15 % is = 18 - ( 15/100 ) x 18
= 18 - 0.15 x 18
= 18 - 2.7
= $ 15.3
Now , the cost of the sweater after sales tax of 8 % is = cost of the sweater after discount + sales tax percentage x cost of the sweater after discount
So , the equation is
The cost of the sweater after sales tax of 8 % is = 15.3 + ( 8/100 ) x 15.3
= 15.3 + 0.08 x 15.3
= 15.3 + 1.224
= $ 16.524
Hence , the total cost of the sweater is $ 16.52

Equation: 5.88/3=p-0.75
The original price for apples was $1.21
Step-by-step explanation:
Equation explanation:
$5.88 divided by 3 pounds of apples = the original price per pound - the $0.75 increase in price
$5.88 for 3 pounds of apples
we divide 5.88 by 3 to see how much money it was per pound
5.88/3=1.96
subtract 1.96 from the price increase of .75
1.96-.75=1.21
A church spire casts a shadow on the level ground. At the tip of the shadow, the tip of the spire lies 25° upward. Walking 100 m closer, the tip of the spire is at an angle of 55°. What must be the height of the spire in Figure 2?
Answer:
The height of the spire must be 69.24 m
Step-by-step explanation:
The information given are;
The initial angle of elevation of the tip of the spire from the tip of the shadow = 25°
The angle of elevation of the tip of the spire from the tip of the shadow after moving 100 m closer = 55°
The change distance moved closer to the church spire = 100 m
Let the base angles of the triangle formed by the two rays of the tip of the spire to the tip of the shadow be 25° and ∠x°
We have;
∠x° and the 55° angle of the ray from the tip of the spire to the tip of the shadow are supplementary angles (angle on a straight line)
Therefore;
∠x° = 180° - 55° = 125°
The calculated angle 125° above, the given 25° and the angle in between the two rays from the tip of the spire to the tip of the shadows are the interior angles of the triangle formed by the two rays of the tip of the spire to the tip of the shadow
Let the angle in between the two rays from the tip of the spire to the tip of the shadows = y
Therefore;
125° + y° + 25° = 180 (Angle sum theorem)
y° = 180° - (125° + 25°) = 30°
By sin rule, we have;
100/(sin (30°)) = (The length of the initial ray from the tip of the spire to the tip of the shadow before the shift)/(sin(125°))
Let the length of the initial ray from the tip of the spire to the tip of the shadow before the shift = l
100/(sin (30°)) = l/(sin(125°))
l = (sin(125°))×100/(sin (30°)) = 163.83 m
The height of the spire, by trigonometric ratio = sin(25°) × 163.83 m = 69.24 m
The height of the spire = 69.24 m.
