Answers

{ x + 2y = 4 * ( 3 )
-3 x + 2y = -4

3 x + 6 y = 12
-3 x + 2 y = -4
---------------------
8 y = 8

y = 8 / 8

y = 1

For x :

x + 2 y = 4

x + 2*(1 ) = 4

x + 2 = 4

x = 4 - 2

x = 2

Hi ... i appreciate you to answer this questuion... $\frac{ {x}^(2) }{ {x}^(4) + 1 }$

Answers

Answer:

$\large \boxed{\sf \ \ (x^2)/(x^4+1)=(1)/(7) \ \ }$

Step-by-step explanation:

Hello,

We know that (let's assume that x is different from 0 as we cannot divide by 0)

$x+(1)/(x)=3$

and we want to estimate

$(x^2)/(x^4+1)$

Let's take the square.

$9=3^2=(x+(1)/(x))^2=x^2+2\cdot x \cdot (1)/(x)+(1)/(x^2)=x^2+2+(1)/(x^2)=(x^4+1)/(x^2)+2$

So, we can write

$(x^4+1)/(x^2)=9-2=7 \n \n\n\text{*** let's take the inverse ***} \n \n(x^2)/(x^4+1)=(1)/(7)$

Hope this helps.

Do not hesitate if you need further explanation.

A fisherman can row upstream at 4mph and downstream at 6mph. He started rowing upstream until he got tired and then started downstream to his start point. How far did the fisherman row if the trip took 3 hours?

Answers

Answer:

Fisherman traveled 14.4 miles.

Step-by-step explanation:

A fisherman's downstream speed = 6 mph

and upstream speed = 4 mph

Let the fisherman traveled x miles he travels upstream.

Time spent in travelling x miles = $(x)/(4)$ hours [Since time = $\frac{\text{distance}}{\text{speed}}$ ]

Similarly when fisherman covers x miles down stream

Time spent in x miles = $(x)/(6)$ hours

Now total time in going upstream and downstream is 3 hours then

$(x)/(4)+(x)/(6)=3$

x $((3+2)/(12))=3$

$((5x)/(12))=3$

5x = 12×3

5x = 36

x = $(36)/(5)=7.2$ miles.

Since fisherman has traveled 2x distance so the answer will be 14.4 miles

Therefore, fisherman traveled 14.4 miles.

total time = upstream time + downstream time
he rowed the same distance both ways.
upstream time = D/4
downstream time = D/6
total time = D/4 + D/6 = 3D/12 + 2D/12 = 5D/12 = 3 hours
D = 3*12/5 = 36/5 or 7.2 miles
where D is the one-way distance. The total distance he rowed is 2*D = 72/5 or 14.4 miles

If an iceberg has a mass of 1800 kg and a volume of 19000 m3, what
is its density?

Answers

Answer:

≈0.0947 kg/m^3

Step-by-step explanation:

p = density

m = mass

v = volume

Formula for density :

p = m/v

We know the mass and volume, so we can simply substitute our values into the equation:

p = m/v

p = 1800kg / 19000 m^3

p = ≈0.0947 kg/m^3

Answers

Answer:

5x + 3y = 15

Step-by-step explanation:

As Line CD passes through points C(3, 5) and D(6, 0), x (the "run") increases by 3 and y (the "rise") decreases by 5. Thus, the slope of line CD is

m = rise / run = -5/3, and in slope-intercept form the following is true:

y = mx + b => 5 = (-5/3)(3) + b, or b = 5.

Then the equation of the line is y = (-5/3)x + 5. Converting this to standard form, we get:

3y = -5x + 15, or 5x + 3y = 15

Integers are _____ rational numbers
A. always
B. somtimes
C. never

Answers

Integers are always rational!

A rational number is a number that can be expressed as $(p)/(q)$ , where p and q are both integers.

So each integer can be expressed as $(itself)/(1)$ , which is always rational as "itself" if an integer!
