Solve 6y + 2x = 14 for x.
Answer:
x = 7 - 3y
Step-by-step explanation:
6y + 2x = 14 (divide all by two)
3y + x = 7 (move 3y to the right to isolate x)
x = 7 - 3y
Answer:
7-3y=x
Step-by-step explanation:
6y+2x=14
2x=14-6y >>> isolate x variable
x=7-3y >>> simplify because everything is divisible by 2
JK has endpoints at J(6,-1) and K(-3,-4). If M is the midpoint of JK, approximately what is JM ?
Answer:
midpoint of J and K = (3/2,-5/2) or (1.5,-2.5)
Step-by-step explanation:
midpoint formula: (((x+x1)/2),((y+y1)/2)))
in this case J(x1,y1), and K(x,y) where J = (6,-1), and K = (-3,-4).
so: (((-3+6)/2),((-4+-1)/2))) = (((3)/2),((-5)/2))) = (1.5,-2.5) or (3/2,-5/2)

Jasmine walks three dogs after school. She brings dog
treats for the dogs. She gives 4 treats to Tucker. Then she splits the
remaining treats between Bogey and Murphy, who get 3 treats each.
How many treats did Jasmine start with? Solve the problem by working
backward, and by writing and solving an equation.
Answer:
if bogey and murphy each get 3 treats and tucker gets 4 then the total is 3+3+4=10
Step-by-step explanation:
Jasmine starts with 10 treats.
What is Unitary Method?The unitary technique involves first determining the value of a single unit, followed by the value of the necessary number of units.
For example, Let's say Ram spends 36 Rs. for a dozen (12) bananas.
12 bananas will set you back 36 Rs. 1 banana costs 36 x 12 = 3 Rupees.
As a result, one banana costs three rupees. Let's say we need to calculate the price of 15 bananas.
This may be done as follows: 15 bananas cost 3 rupees each; 15 units cost 45 rupees.
Given:
She gives 4 treats to Tucker.
Then splits the remaining treats between Bogey and Murphy, who get 3 treats each.
So, if bogey and murphy each get 3 treats and tucker gets 4 then
= 3+3+4
=10 treats
Hence, at beginning Jasmine starts with 10 treats.

What are the roots of the quadratic equation x²-81=0
Answer:
What are the roots of the quadratic equation x²-81=0
Answer:
x = ± 9
Step-by-step explanation:
Given
x² - 81 = 0 ( add 81 to both sides )
x² = 81 ( take the square root of both sides )
x = ± [tex]\sqrt{81}[/tex] = ± 9
Thus roots are x = - 9, x = 9

O y=-5x+12
O 5x+y=12
O y-12=5(x-0)
O 5x+y=-1
Answer:
Step-by-step explanation:
y=-5x+12
10x+2y=-2
Subtract 10x to the other side of the equation and you will get 2y=-10x-2
Then divide both side by 2 to get y by itself
It will lead you to y=-5x+1
Notice that your point is (0,12) and it says parallel so you will keep your slope but your y-intercept will change
Final answer: y=-5x+12
I believe it's y= -5x+12. I really hope this helps. Happy schooling!!

9514 1404 393
Answer:
8 units
Step-by-step explanation:
Displacement is the area under the velocity curve. The area of interest is in the shape of a trapezoid, so we can use the formula ...
A = (1/2)(b1 +b2)h
to find the area.
Here, b1=3, b2=1, h=4, so the area is ...
A = (1/2)(3 +1)(4) = 8
The displacement is 8 units in the time from t=1 to t=4.

Justin owns a food truck that sells tacos and burritos. He only has enough supplies to make 110 tacos or burritos. He sells each taco for $3.25 and each burrito for $5.75. Justin must sell a minimum of $520 worth of tacos and burritos each day. If 39 tacos were sold, determine the maximum number of burritos that the Justin could sell that would meet the requirements. If there are no possible solutions, submit an empty answer.
Answer:
so looks its an easy one
110 - 39 = 71
71 x 5.75 = 408.25
39 x 3.25 = 126.75
408.25 +126.75 = 535
71 burritos and 39 tacos = 535 dollars
69 burritos
What is mathematical expression?
A mathematical expression is defined as the collection of the numbers variables and functions by using signs like addition, subtraction, multiplication, and division.
Tacos sold = 39
Burritos sold = x
Let x be the number Burritos sold
each taco sold for $3.25
each burrito sold for $5.75.
Total sell = $520
Now according to the given question,
39*3.25 + x*5.75 = 520
126.75 + 5.75x = 520
5.75x = 393.25
x = 68.39
x ≈ 69
Therefore, Justin has to sell 69 burritos to meet the requirements.

Independent and Dependent Samples Which of the following involve independent samples?
A) Data Set 14 "Oscar Winner Age" in Appendix B includes pairs of ages of actresses and actors at the times that they won Oscars for Best Actress and Best Actor categories. The pair of ages of the winners is listed for each year, and each pair consists of ages matched according to the year that the Oscars were won.
B) Data Set 15 "Presidents" in Appendix B includes heights of elected presidents along with the heights of their main opponents. The pair of heights is listed for each election.
C) Data Set 26 "Cola Weights and Volumes" in Appendix B includes the volumes of the contents in 36 cans of regular Coke and the volumes of the contents in 36 cans of regular Pepsi.
Answer:
(A) Independent
(B) Independent
(C) Independent
Step-by-step explanation:
Independent samples are those samples are drawn from two different population.
Dependent samples are sample collected from the same population but at different times. They are also known as matched pair samples.
(A)
The data collected is for the pair of ages of actresses and actors at the times that they won Oscars for Best Actress and Best Actor categories.
That is the data is in the form (x, y). Here x represents the age of actresses and y represents the age of actors.
Since the data is collected from two different population of male and female, the sample are independent.
(B)
The data collected is for the heights of elected presidents along with the heights of their main opponents.
Again the data is in the form (x, y). Here x represents the heights of elected presidents and y represents the heights of the main opponents.
The samples collected is independent.
(C)
The data collected is for the volumes of the contents in 36 cans of regular Coke and the volumes of the contents in 36 cans of regular Pepsi.
Again the data is in the form (x, y). Here x represents the volumes in the regular Coke cans and y represents the volumes in the regular Pepsi cans.
The samples collected is independent.

What is the phenomenon that many types of data analysis become significantly harder as the dimensionality of the data increases? a. The Curse of Dimensionality b. The Phenomenon of Reduction c. The Curse of Reduction d. The Phenomenon of Dimensionality
Answer:
a. The Curse of Dimensionality
Step-by-step explanation:
The phenomenon that refers to this is known as the Curse of Dimensionality. This phenomenon is basically the specific complications that only occur when dealing with far larger data sets that contain various dimensions, while these complications do not exist in smaller and less complex data sets. The larger the data set tends to get, the more complications arise. This is usually solved with Dimensionality reduction which shrinks the data sets by targeting specifics of the data and separating it.

Step-by-step explanation:
simplify 36 - 4.5x + 36 to -4.5x + 72
simplify 102 - 7.5x - 60 to -7.5x + 42
add 7.5x to both sides
simplify -4.5x + 72 + 7.5x to 3x + 72
subtract 72 from both sides
simplify 42 - 72 to -30
divide both sides by 3
simplify 30/3 to 10

Solve the equation: |2x + 5| = 11.
Answer:
x = -8 and x = 3
Step-by-step explanation:
Split the equation into 2 possible cases:
2x + 5 = 11
2x + 5 = -11
Then, solve these 2 equations.
2x + 5 = 11
2x = 6
x = 3
2x + 5 = -11
2x = -16
x = -8
So, the 2 solutions are x = -8 and x = 3
