Answer:
(C) x = 0 and x = 2Step-by-step explanation:
Given equation:
x/5 = x²/(4x + 2)Cross multiply and simplify:
x(4x + 2) = 5x²5x² = 4x² + 2xx² - 2x = 0x(x - 2) = 0x = 0or
x - 2 = 0 ⇒ x = 2Correct choice is C
[tex]\\ \sf\longmapsto \dfrac{x}{5}=\dfrac{x^2}{4x+2}[/tex]
[tex]\\ \sf\longmapsto x(4x+2)=5x^2[/tex]
[tex]\\ \sf\longmapsto 4x^2+2x=5x^2[/tex]

If f(x - 1) = 2x + 3 for all values of x, what is the
value of f(-3)?
Answers
Answer:
-1
Step-by-step explanation:
F(x - 1) = 2x + 3.
Rewrite the right side (2x + 3)
F(x - 1) = 2[ x ] + 3
F(x - 1) = 2[ x - 1 + 1 ] + 3 = 2 [ (x - 1) + 1 ] + 3
= 2 (x - 1) + 2 + 3
= 2(x - 1) + 5
replace "x - 1" with "-3" :
F(-3) = 2(-3) + 5 = -1

(8.
)
Answers
Answer:
The answer is 5
Step-by-step explanation:
Since we already know what x we can just substitute it.
5(8)-2y=30
5 times 8 is 40
40-2y=30
Subtract 40 on both sides:
-2y=-10
Divide -2 on both sides:
y=5

What is the distance between two points with coordinates (32,12,5) and (20,3,13) in space?
Answers
The distance between two points with the given coordinates in space is;
Distance = 17 units
We are given the coordinates;
(32, 12, 5)
(20, 3, 13)
Formula for the distance between two points that have (x, y, z) coordinates is;d = √((x₂ - x₁)² + (y₂ - y₁)² + (z₂ - z₁)²)
From the equation given to us, we can see that;
x₁ = 32
x₂ = 20
y₁ = 12
y₂ = 3
z₁ = 5
z₂ = 13
Using the formula for the distance, we have;d = √((20 - 32)² + (3 - 12)² + (13 - 5)²)
d = √(144 + 81 + 64)
d = √289
d = 17
Thus, the distance between the two points is 17 units

A flying carpet flies 2.4 miles with the wind in the same amount of time it flies 1.4 miles against the wind. The wind speed is 4 mph. What is the speed of the flying carpet in still air?
Answers
Answer:
[tex]15.2~mph[/tex]
Step-by-step explanation:
Let the time flown by the flying carpet be [tex]t[/tex]. Then, we have that [tex](2.4)/t=(1.4)/t+2*4[/tex].
We multiply both sides of the equation by [tex]t[/tex] to get [tex]2.4=1.4+8t[/tex].
We subtract [tex]1.4[/tex] from both sides to get [tex]1=8t[/tex].
We divide both sides of the equation by [tex]t=1/8[/tex].
We know that the speed of the flying carpet in still wind is the average of the rates of the speed of the flying carpet with the wind and against the wind.
The speed with wind is [tex](2.4)/(1/8)=19.2[/tex]mph.
The speed against wind is [tex](1.4)/(1/8)=11.2[/tex]mph.
The speed in still wind is [tex](19.2+11.2)/2=(30.4)/2=15.2[/tex].
Therefore, the answer is [tex]\boxed{15.2~mph}[/tex] and we're done!
The speed of the flying carpet in still air is 15.2 mph
Let x represent the speed of the flying carpet in still air, and t represent the time.
Speed = distance/time
Since the wind speed is 4 mph, hence:
When flying with the wind:
x + 4 mph = 2.4/t (1)
When flying against the wind:
x - 4 mph = 1.4/t (2)
Dividing equation 1 by 2 gives:
(x + 4) / (x - 4) = 2.4/1.4
1.4x + 5.6 = 2.4x - 9.6
x = 15.2 mph
The speed of the flying carpet in still air is 15.2 mph
