Inversely proportional means as one variable increases the other variable decreases.
In this problem, x is doubled which means it's increased, therefore, y is decreased.
7 / 2 = 3.5
The new value of y is 3.5

Question 4
Point P is presently located at the origin. Move P, and observe how the rotated images change. Be sure that neither the images nor the preimage
overlap. Record the distances of the vertices of the preimage AABC from P. Do the same for the other images. Round all of your answers to the
hundredths place.
Thanks so much
Answer:here ya go boys
Step-by-step explanation:
Answer:
No matter where the center of rotation is located on the coordinate plane, each point in the preimage is the same distance from the point of rotation as its corresponding point in the rotated images. This distance is not affected by changing the location of P. Although this investigation covered vertices only, it's clear that any point on a shape or figure will be affected similarly.

y ∝ 1 √ x If y = 5 when x = 49 find, y when x = 25
Answer:
y = 1/7
Step-by-step explanation:
y ∝ 1/√x ⇒ y = k/√xy = 5, x = 49 ⇒ 5 = k/√49 ⇒ 5 = 7k ⇒ k = 5/7y = 5/(7√x) ⇒ x = 25 ⇒ y = 5/(7√25) = 5/(7·5) = 1/7The value of x is 25 then y is 7.
What is Proportionality?In mathematics, proportionality denotes a linear relationship between two quantities or variables. Both quantities increase in size when one doubles, and both decrease in size when one drops to a tenth of its original value.
Given:
y ∝ 1 √ x
and, y= 5 when x= 49
So, the relation will be
y ∝ 1/√x
y = k/√x
So, 5 = k/√49
5 = k /7
k = 35
Now, k = y/ √x
35 = y √25
35 = 5y
y = 7
Hence, when x is 25 then y is 7.

x + 84 = 4x
These are equal because they're vertical angles. Now, let's subtract x from both sides.
84 = 3x
Divide both sides by 3
28 = x
x + 84 = 28 + 84 = 112 degrees

Solve the following system of equations using the elimination method. 2x + 4y = 10 –2x + y = –15
Answer:
(7, - 1 )
Step-by-step explanation:
Given the 2 equations
2x + 4y = 10 → (1)
- 2x + y = - 15 → (2)
Adding the 2 equations term by term eliminates the term in x, that is
5y = - 5 ( divide both sides by 5 )
y = - 1
Substitute y = - 1 into either of the 2 equations and solve for x
Substituting into (1)
2x + 4(- 1) = 10
2x - 4 = 10 ( add 4 to both sides )
2x = 14 ( divide both sides by 2 )
x = 7
Solution is (7, - 1 )
(7, - 1 )
Step-by-step explanation:
Given the 2 equations
2x + 4y = 10 → (1)
- 2x + y = - 15 → (2)
Adding the 2 equations term by term eliminates the term in x, that is
5y = - 5 ( divide both sides by 5 )
y = - 1
Substitute y = - 1 into either of the 2 equations and solve for x
Substituting into (1)
2x + 4(- 1) = 10
2x - 4 = 10 ( add 4 to both sides )
2x = 14 ( divide both sides by 2 )
x = 7
Solution is (7, - 1 )

Answer:
The nuclear utility environment is one of strict cost control under prescriptive regulations and increasing public scrutiny. This paper presents the results of A Total Quality approach, by a dedicated team, that addresses the need for increased on-site spent fuel storage in this environment. Innovations to spent fuel pool reracking, driven by utilities' specific technical needs and shrinking budgets, have resulted in both product improvements and lower prices. A Total Quality approach to the entire turnkey project is taken, thereby creating synergism and process efficiency in each of the major phases of the project: design and analysis, licensing, fabrication, installation and disposal. Specific technical advances and the proven quality of the team members minimizes risk to the utility and its shareholders and provides a complete, cost effective service. Proper evaluation of spent fuel storage methods and vendors requires a full understanding of currently available customer driven initiatives that reduce cost while improving quality. In all phases of a spent fuel reracking project, from new rack design and analysis through old rack disposal, the integration of diverse experts, at all levels and throughout all phases of a reracking project, better serves utility needs. This Total Quality environment in conjunction with many technical improvements results in a higher quality product at a lower cost

Question: 0.4p + 1.7 < 3.3
Answer:
p < 4
Step-by-step explanation:
We are given 0.4p + 1.7 < 3.3.
We solve it like a normal equation by isolating the variable p. Subtract 1.7 from both sides:
0.4p + 1.7 - 1.7 < 3.3 - 1.7
0.4p < 1.6
Divide both sides by 0.4:
p < 1.6/0.4
p < 4
Thus, our possible solutions are p < 4.

combine the like terms which leaves you with 8-19x=65
subtract 8 from both sides 8-19x-8=65-8 which leaves you with -19x=57

My favorite group, The Lumineers, is coming to Prescott and YC for a concert. Tickets are sold in three levels, $45, $65, and $95 depending on seats. The auditorium seats 1100 people total on the different levels; for them to come to YC we need to sell $66,500 worth of tickets and the auditorium has as many cheap ($45) tickets as the sum of the other two levels ($65 and $95).
Answer:
550 $45 tickets, so $24750 worth of $45 tickets
Step-by-step explanation:
If $45 tickets=x, $65=y, and $95=z, then the question is saying x=y+z. And if x+y+z=1,100, then x=1100/2, so 550 $45 tickets. 550*45 is $24750
Determine whether the equation is always, sometimes, or never true. 6(x + 1) = 2(5 + 3x)
Answer:
never true
Step-by-step explanation:
6(x + 1) = 2(5 + 3x)
distribute
6x + 6 = 10 + 6x
combine like terms by subtracting 6x and 6 from both sides
0 = 4
that is not a true statement, so this equation is never true
jose bought 750 bags of peanuts for $375.00. He tends to sell each bag for 0.15 more than he paid. how much he change for each bag
Answer:
$0.65
Step-by-step explanation:
Jose bought 750 bags for $375.00
Each bag cost $375/750= $0.50
He intends to sells them for $0.15 more
He should charge : $0.5 +$0.15=$0.65
Answer:
cost of 750 bags =$375
cost of 1 bag = 375/75=5
he want 0.15 more for each
so he had to sell each bag in 5 +0.15=5.15

|9x - 9| = 36
To solve for the first solution, simply disregard the absolute value signs.
9x - 9 = 36
Add 9 to both sides
9x = 45
Divide both sides by 9
x = 5
To find the second solution, disregard the absolute value signs and change 36 to -36
9x - 9 = -36
Add 9 to both sides
9x = -27
Divide both sides by 9
x = -3
