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

Answer:

The number is 17.

Step-by-step explanation:

Let x be the unknown number.

4 times the sum of a number plus 7 would be

4x + 7

44 less than the unknown number (x) would be

x - 44

Now we connect everything.

4x + 7 = x - 44

4x - x = -44 - 7

3x = -51

x = -17

The algebraic representation of the expression is 4(x + 7)  = x - 44

From the question, we have the following parameters that can be used in our computation:

four times the sum of a number and 7 is 44 less than the number

By definiton:

Sum means plus

Less than means minus

Using the above as a guide, we have the following:

4 * (x + 7) = x - 44

So, we have

4(x + 7)  = x - 44

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

Answer:

y=2x+7

Step-by-step explanation:

find (-5,-3)

use the slope to find the y intercept

intercept is (0,7)

use formula y=mx+b to plug in numbers

(slope is m and y intercept is b)

y=mx+b

Answer:

Domain : R−{−1,3}

Range: R

Step-by-step explanation:

Equate the denominator(x2−2x−3) to zero, then solve the equation for x

→x2−2x−3=0

→x=−(−2)±√(−2)2−4⋅(1)⋅(−3)2⋅1

→x=1±2

⇒x=−1 and x=3

This means that, when x=−1 or 3, we have the x2−2x−3=0

Implying that f(x)=x0 which is undefined.

Hence, the domain is all real numbers except −1

and 3

Also written as Df=(−∞,−1)∪(−1,3)∪(3,+∞)

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)

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

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

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
