When x = 2, y = 4.
Find y when x = 4
(3 Points)
Answers
Answer:
y = 0.5 at x = 4
Step-by-step explanation:
According to question,
y is inversely proportional to cube of x i.e.
[tex]y\propto \dfrac{1}{x^3}\\\\y=\dfrac{k}{x^3}[/tex]
or
[tex]k=yx^3[/tex]
Put x = 2 and y = 4 in above expression to find k.
[tex]k=4\times (2)^3\\\\=32[/tex]
Now put x = 4 to given equation to find y.
[tex]y=\dfrac{32}{4^3}[/tex]
y = 0.5 or 1/2
So, the value of y is 0.5 when x = 4.

2x - y = -2
9x = 13
11x = -7
9x = -7
Answers
Answer:
See answers below with explanations
Step-by-step explanation:
Problem 1:
One number is 10 less than twice another.
This translates to n=2m-10
Their difference is 31
This translates to n-m=31
n-m=31
(2m-10)-m=31
m-10=31
m=41
n-41=31
n=72
Therefore the larger number is (B) 72
Problem 2:
Use elimination:
2x + y = 7
- 2x -3y = -1
4y = 8
y = 2
2x+2=7
2x=5
x=2.5
Therefore the solution is (A) {(2.5,2)}
Problem 3:
Use elimination:
x - y = 1
- x + y = -1
-2y = 2
Check if each answer eliminates to -2y=2:
2x - 3y = 6
4x + y = 4
-2x - 4y = 2 NO
4x - 3y = 6
4x - y = -4
-2y = 10 NO
4x + 3y = -6
4x - y = 4
4y = -10 NO
Neither answer is correct
Problem 4:
No visible items to match
Problem 5:
2(2x - y = -2)
4x - 2y = -4
x + 5y = 3
4x - 2y = -4
5x + 3y = -1

To the nearest hundredth, which is the value of x in the solution of the following system? 3.5x - 2.8 = -4.67x + 12.5 Select one: a. -3.75 b. -1.87 c. 1.87 d. 3.75
Answers
Answer:
C. 1.87
Step-by-step explanation:
3.5x - 2.8 = -4.67x + 12.5
3.5x + 4.67x = 12.5 + 2.5
8.17x = 15.3
x = 15.3 ÷ 8.17
x = 1.87270501836
So, the closest choice to 1.87270501836 is 1.87, so the answer is C.
Hence, the answer would be C. 1.87. I am 100% sure on this, for I am a pro.

The shadow of a vertical tower is 52.5 meters long when the angle of elevation of the sun is x degrees. The height of the tower is 41 meters. Find the angle of elevation rounded to the nearest degree.
Answers
Answer:
Angle of Elevation = 38°
Step-by-step explanation:
Angle of Elevation formula is given as
tan x = Opposite /Adjacent
Where
x = Angle of Elevation
Opposite = Height of the tower = 41 meters
Adjacent = Shadow of the vertical tower = 52.5 meters
Hence:
tan x = 41 m/52.5m
x = arc tan (41 m/52.5m)
x = 37.988141726°
Approximately to the nearest degree x = 38°
