Answer:
The coordinates of point B are (-4,5/2)
Step-by-step explanation:
The transformation B(-8,5) →(-8/2, 5/2) represents a dilation centered at the origin.
What is a transformation?When a point is relocated from its original place to a new location, it is changed. Different transformations include translation, rotation, reflection, and dilation.
You can dilate figures on the coordinate plane. The origin is commonly used as the dilatation center. You can identify the points in the picture if you deform a figure centered at the origin by multiplying the coordinates of the points in the preimage by the scale factor.
We have been given that Point B(-8,5) is dilated from the origin by scale factor r = 1/2
The scale factor i.e. 0.75 is multiplying the coordinates of the points B(-8,5)
So the coordinates of point B = (-8/2, 5/2)
Thus, the transformation B(-8,5) →(-8/2, 5/2) represents a dilation centered at the origin.

Danielle is ordering costumes for her dance recital. The company Danielle is ordering from charges $19 per costume and a shipping fee of $9. Based on this information, which function can be used to represent the relationship between the total cost, k, and the number of costumes Danielle orders, u? A. k = 9u + 19 B. k=19u−9 C. k = 19u + 9
D. k=9u−19
PLEASE HURRY ILL MAKE MOST BRAINLIEST!!!!
Answer:
Step-by-step explanation:
C. Cost = $19 x u + $9shipping fee
So k = 19u + 9
The function that represent the information is k = 19u + 9
The shipping fee = $9
The company charges $19 per costume.
The shipping fee is acting like a constant in the linear equation while the amount charged for the costumes is dependent on the value u, which is the number of costumes purchased.
k = total cost
number of costumes she orders = u
Therefore, the equation can be represented as follows
k = 19u + 9

Summer and Autumn are friends who live 25 miles apart and they are training for a long race. On wednesday after school, they ran toward each other’s houses to meet up. They left their houses at 4pm and met at 6 pm. Summer ran an average rate of 8 1/2 miles per hour
Complete question is;
Summer and Autumn are friends who live 25 miles apart and they are training for a long race. On wednesday after school, they ran toward each other’s houses to meet up. They left their houses at 4pm and met at 6 pm. Summer ran an average rate of 8 ½ miles per hour faster than autumn. What is the average speed of each?
Answer:
Autumn's average speed is 1.3158 mph
Summer's average speed is 11.1843 mph
Step-by-step explanation:
We are told that they live 25 miles from each other.
They left their houses at 4pm and met at 6 pm. This means they met 2 hours later.
Now, summer ran 8.5 mph faster than autumn.
This means if autumn's speed is "x", then summer ran 8.5x mph
Thus, total distance covered by summer is; d_summer = 8.5x * 2 = 17x
Total distance by autumn is; x * 2 = 2x
Since their houses are 25 miles apart.
Thus;
17x + 2x = 25
19x = 25
x = 25/19
x = 1.3158 mph
Thus, autumn's speed is 1.3158 mph
Summer's speed is 1.3158 × 8.5 = 11.1843 mph

Wellington never paid attention in school when teachers taught math and he never truly understood how to manage his money. He is now an adult and does not have any real skills so lets find out what happened to his money. He made $2400 dollars but after federal and state taxes, social security, and health insurance there are $550 that are automatically taken out. Then he must pay his rent which is $1,000. Then he must pay his car note and insurance which come up to $700. He has to divide the remaining total up equally and make it last for 15 days. How much will he have to spend on each of those 15 days?
Answer:
$10
Step-by-step explanation:
Total amount earned = $2400
Less: federal and state taxes, social security, and health insurance = $550
Balance = $2400 - $550
=$1,850
Less : Rent = $1,000
Balance = $1,850 - $1,000
= $850
Less: insurance = $700
Balance = $850 - $700
= $150
He has to divide the remaining total up equally and make it last for 15 days
Amount to spend per day = $150 / 15 days
= $10 per day

Entre Ana y Sergio tienen $500, pero Sergio tiene el doble de dólares que Ana. ¿Cuánto tiene cada uno? Halle la solución por el Método Gráfico Ana : x ; Sergio :y { + = = { + = − + = �
Answer:
Ana tiene 166,67 dólares, mientras que Sergio tiene 333,33 dólares.
Step-by-step explanation:
Consideramos que la mejor estrategia para resolver este problema consiste en leer cuidadosamente cada frase del enunciado, traducirlo matemáticamente y utilizar software gráfico para determinar la solución de las ecuaciones resultantes:
1) Entre Ana y Sergio tienen $ 500
[tex]x + y = 500[/tex] (Eq. 1)
Donde:
[tex]x[/tex] - Cantidad de dinero de Ana, medida en dólares.
[tex]y[/tex] - Cantidad de dinero de Sergio, medida en dólares.
2) Sergio tiene el doble de dólares que Ana
[tex]2\cdot x - y = 0[/tex] (Eq. 2)
En consencuencia, tenemos un sistema de dos ecuaciones lineales con dos incógnitas, lo que nos permite la posibilidad de encontrar una solución única y utilizar un plano cartesiano para su resolución. Mediante software gráfico (véase imagen adjunta) encontramos que la solución del sistema es:
[tex](x,y) = (166,67, 333,33)[/tex]
Ana tiene 166,67 dólares, mientras que Sergio tiene 333,33 dólares.

Hideo Yamata makes a deposit of $2,235. He remembers that the checks he deposited total twice the amount of currency he deposited. How much did he deposit in checks?
Answer:
Total amount deposited in checks is $1490
Step-by-step explanation:
Amount deposited by Yamata = $2235.
The amount of checks is twice the amount of currency deposited. Let the amount of currency deposited be represented by x.
So that,
Amount of checks = 2x, then;
2x + x = 2235
3x = 2235
x = [tex]\frac{2235}{3}[/tex]
= 745
The amount of currency deposited is $745.
Therefore,
amount deposited in checks = 2 x $745
= 1490
Total amount deposited in checks is $1490.

you invest 10,000 dollars into two accounts, one earning 5% interest and the other earning 8% interest. If the total annual interest earned is 590 dollars, how much do you invest into each account? PLZ SHOW WORK
Answer:
$7,300 was invested in the 14% account while $2,700 was invested in the 8% interest account
Step-by-step explanation:
Let the amount invested in first account be $x while the amount for second account is $y
Mathematically;
x + y = 10,000 •••••••••(i)
Interest on first account
= 14% of x = 14/100 * x
Interest on second account
= 8% of y= 8/100 * y
Adding all together will give total
14/100 * x + 8/100 * y = 1238
Multiply through by 100
14x + 8y = 123800 •••••••(ii)
From equation 1, x = 10,000 - y
Insert this into second equation
14(10,000-y) + 8y = 123,800
140,000 - 14y + 8y = 123,800
140,000 - 6y = 123,800
6y = 140,000 - 123,800
6y = 16,200
y = 16,200/6
y = $2,700
Recall
x + y = 10,000
x = 10000 - y
x = 10,000 - 2,700
x = $7,300

Logan bought a baseball bat on a trip. The baseball bat is 29 inches long Logan thinks he can bring the baseball bat home in his suitcase. Is he correct? Use your understanding of the Pythagorean theorem to explain your answer
Answer:
Step-by-step explanation:
Kindly find attached a description of Logan's suit case
given data
dimension of suitcase
adj, length=24in
opp, width=18in
dimension of base ball bat= 29in
we want to know if the bat can fit in the case, a way out is to solve for the diagonal or hypotenuse of the case using Pythagoras theorem.
we know that
hyp^2= opp^2+adj^2
hyp=√opp^2+adj^2
hyp=√18^2+24^2
hyp=√324+576
hyp=√900
hpy=30in
this means that the diagonal of the case is 30 in, seeing that the bat is 29 in, the bat cannot fit into the case
Since in the given situation, the diagonal of the case is 30 in and the baseball bat is 29 in, so the bat cannot fit into the case.
Pythagorean theorem:The dimension of a suitcase is adj length=24in and opp width=18in
Now here we apply the above theorem for determining the diagonal or hypotenuse
So, the calculation is as follows:
[tex]hyp^2= opp^2+adj^2\\\\hyp=\sqrt opp^2+adj^2\\\\hyp=\sqrt 18^2+24^2\\\\hyp=\sqrt324+576\\\\hyp=\sqrt900[/tex]
hyp=30in
Due to the above calculations, we can say that the bat cannot fit into the case
