Answer:
k =1
Step-by-step explanation:
3x + y = -7
y = -3x - 7
m = -3
Parallel lines have same slope
[tex]Slope = -3\\\\\dfrac{8-[-1]}{-2-k}=-3\\\\\\\dfrac{8+1}{-2-k}=-3\\\\\dfrac{9}{-2-k} = -3[/tex]
Cross multiply,
9 = -3(-2-k)
9 = 6 + 3k
9-6 = 3k
3 = 3k
3/3 = k
k = 1

Find the surface area of a cube
with side length 8.5 cm.
=========================================================
Explanation:
A cube has 6 identical faces, all of which are squares.
Each square has a side length of 8.5 cm, so its area is (8.5)^2 = 72.25 sq cm.
The overall surface area, aka the area of all 6 faces combined, is 6*72.25 = 433.5 square cm
Answer:
A=433.5cm²
Step-by-step explanation:
A=6a2=6·8.52=433.5cm²

Answer:
(0, -3)
Step-by-step explanation:
the midpoint of (3 x, -2) and (-4, 5y) is (1,4). find x, -y
Answer:
(x,-y): (2,-2)
Step-by-step explanation:
M=(x+x)/2,(y+y)/2
Given (1,4)=
[tex] \frac{3x - 4}{2} [/tex]
This implies:
[tex]1 = \frac{3x - 4}{2} [/tex]
[tex]3x - 4 = 2 \\ 3x = 2 + 4 \\ \frac{3x }{3} = \frac{6}{3} \\ x = 2[/tex]
In a similar way,
[tex]4 = \frac{ - 2 + 5y}{2} \\ - 2 + 5y = 8 \\ 5y = 10 \\ y = 2[/tex]
The question demanded (x,-y)
Hence(2,-2) is the answer

One challenge of federalism is that
power and authority are concentrated in the central government and can take away people’s rights
sometimes officials from different levels of government disagree on who should be in charge of a situation
local governments have the most power, which creates problems for trade with other nations
officials from state governments have too many rules to follow to be effective leaders
Answer:
local governments have the most power
Step-by-step explanation:
I hope this is right, but federalism gives more power to the state, so local governments could potentially have more power.

Step-by-step explanation:
You rent an apartment that costs \$800$800 per month during the first year, but the rent is set to go up 9.5% per year. What would be the rent of the apartment during the 9th year of living in the apartment? Round to the nearest tenth (if necessary).\
Pls help I'm dying here
Answer:
Monthly rent for Year 9: $1,653.5
Total cost of rent for the whole 9th year: $19,841.9
Step-by-step explanation:
Given the monthly rent of $800 for an aparment, for which it is set to increase by 9.5% annually:
Increase in the Monthly Cost of RentYear 1:The monthly rent will stay at $800 for the first year.
Year 2:For year 2, we must add the 9.5% increase in the monthly rent. In order to determine the 9.5%, simply multiply the monthly rent by 0.095 (the decimal equivalent of 9.5%), then add the product to the monthly rent in year 1 of $800.
9.5% increase for Year 2: $800 × 0.095 = $76
Monthly rent in Year 2: $800 + $76 = $876
Year 3:For year 3, we must add the 9.5% increase in the monthly rent from Year 2 ($876).
9.5% increase for Year 3: $876 × 0.095 = $83.22
Monthly rent in Year 3: $876 + $83.22 = $959.22
Year 4:For year 4, we must add the 9.5% increase in the monthly rent from Year 3 ($959.22).
9.5% increase for Year 4: $959.22 × 0.095 = $91.13
Monthly rent in Year 4: $959.22 + $91.13 = $1,050.35
Year 5:For year 4, we must add the 9.5% increase in the monthly rent from Year 4 ($1,050.35).
9.5% increase for Year 5: $1,050.35 × 0.095 = $99.78
Monthly rent in Year 5: $1,050.35 + $99.78 = $1,150.13
Year 6:9.5% increase for Year 6: $1,150.13 × 0.095 = $109.26
Monthly rent in Year 6: $1,150.13 + $109.26 = $1,259.39
Year 7:9.5% increase for Year 7: $1,259.39 × 0.095 = $119.64
Monthly rent in Year 7: $1,259.39 + $119.64 = $1,379.03
Year 8:9.5% increase for Year 8: $1,379.03 × 0.095 = $131.00
Monthly rent in Year 8: $1,379.03 + $131.00 = $1,510.04
Year 9:9.5% increase for Year 9: $1,510.04 × 0.095 = $143.45
Monthly rent in Year 9: $1,510.04 + $143.45 = $1,653.50
Yearly Cost of Rent:In order to determine the yearly cost of renting an apartment, simply multiply monthly rent by 12. In other words:
Year 1: $800 × 12 = $9600
Year 2: $876 × 12 = $10,512
Year 3: $959.22 × 12 = $11,510.64
Year 4: $1,050.35 × 12 = $12,604.15
Year 5: $1,150.13 × 12 = $13,801.55
Year 6: $1,259.39 × 12 = $15,112.69
Year 7: $1,379.03 × 12 = $16,548.40
Year 8: $1,510.04 × 12 = $18,120.50
Year 9: $1,653.50 × 12 = $19,841.94
Therefore, due to the 9.5% annual increase in rent, the monthly cost of an apartment during the 9th year is $1,653.5, or $19,841.9 (12-months' worth of rent).
45 divided by 855 show your work!
Answer:
45 divided by 855 is a very odd number however 855 divided by 54 is 19 ... because 45 multiply by 19 is 855
How do I solve
-3x+y=24
-2x=+18+5y
Answer:
Let's solve by eliminating x. Since 18 is the lowest common multiple , let's multiply the first equation by 3 and the second by -2.
18x−21y=24
−18x+10y=−2
Add the two equations.
−11y=22
Divide by -11 to isolate y.
y=−2
Substitute y=−2 into either of the 2 equations, I'll just use the second one.
9x+10=1
9x=−9
x=−1
Step-by-step explanation: that is your anwser

2. The electrical resistance R of a wire varies inversely with the square of its diameter d. If a wire with a
diameter of 3 millimeters has a resistance of 0.4 ohm, find the resistance of a wire having the same
length and a diameter of 8 millimeters.
Answer:
[tex]0.225 \Omega =225 m\Omega[/tex]
Step-by-step explanation:
We know (Ohm second law) that [tex]R= \frac{k}{d^2}[/tex] where k inlcudes the rest of the parameters (material, lenght). In our situation we have k= [tex]0.4\cdot9 \Omega mm^2[/tex]. The moment the diameter becomes 8mm R becomes
[tex]R= {{0.4\cdot 9}\over{16}} \Omega = 0.225 \Omega[/tex]
