Write the Pythagorean triplet whose one of the numbers is 4. Explain your method.

Answer:

[tex] \boxed{ \bold{ \huge{ \sf{x = 29}}}}[/tex]

Step-by-step explanation:

[tex] \sf{ - 3(3 + x) + 4(x - 6) = - 4 }[/tex]

Distribute -3 through the parentheses

Similarly, Distribute 4 through the parentheses

⇒[tex] \sf{ - 9 - 3x + 4x - 24 = - 4}[/tex]

Collect like terms

⇒[tex] \sf{x - 9 - 24 = - 4}[/tex]

Calculate

⇒[tex] \sf{x - 33 = - 4}[/tex]

Move 33 to right hand side and change it's sign

⇒[tex] \sf{x = - 4 + 33}[/tex]

Calculate

⇒[tex] \sf{x = 29}[/tex]

answer: 7(x-1)

hope this helps you

Answer: The answer is 7(x - 1).

Step-by-step explanation:

So far, we know that the givens are:

7 times the difference of a number and 1

We just need to understand what it says:

7 times ( difference of a number and 1)        

So "the number" can be any number, but you have to replace it with a variable such as n, s, x, etc. And by the way, difference is from subtraction, the result of the subtraction of 1 from the unknown number. Using this, we get:

7(x - 1)

Hence the answer!

Answer: B. $29.25

Step-by-step explanation:

Given, Beginning price =  $24.75

Over the next 5 days,

On Monday, gain of  $2.50 represented by + $2.50.

On Tuesday, loss of $3.25 represented by - $3.25 .

On Wednesday,  loss of $0.75 represented by - $0.75.

On Thursday, gain of $1.25 represented by + $1.25.

On Friday, gain of $4.75 represented by + $4.75.

Price of the share of stock at the end of Friday = (Beginning price)+ ( + $2.50 - $3.25- $0.75+ $1.25+ $4.75)

= $( 24.75 + 2.50 -3.25 -0.75 +1.25 +4.75)

= $29.25

Hence, the correct option is B. $29.25.

Answer:

The inverse is 1/2x +4

Step-by-step explanation:

g(x)=2x -8​

y = 2x-8

Exchange x and y

x = 2y-8

Solve for y

x+8 = 2y-8+8

x+8 = 2y

Divide by 2

1/2 x + 8/2 = 2y/2

1/2x +4 = y

The inverse is 1/2x +4

Answer:

y = 1/2x + 4

Step-by-step explanation:

The first equation is y = 2x - 8

switch out y for x

x = 2y - 8

add 8 to both sides

2y = x + 8

divide by 2 on each side

y = 1/2x + 4

Plug in the given values

[tex]d = \sqrt{(3 - 4)^{2} + ( - 7 - 6)^{2} } \\ d = \sqrt{( - 1)^{2} + {( - 13)}^{2} } \\ d = \sqrt{1 + 169} \\ d = \sqrt{170} = 13.0[/tex]

Answer:

C = 113.04

Step-by-step explanation:

arc ACB = (Ф/360) * 2πr

81.64 = (260/360) * 2 * π * r

r = (81.64 * 360)

         2 * π

r = 17.99 cm

Circumference = 2 * π * r

C = 2 * π * 17.99

C = 113.04

Answer:

[tex]\sqrt{7}[/tex], 2.8, [tex]\pi[/tex], [tex]\sqrt{17}[/tex], 4.6

Step-by-step explanation:

To order the numbers from least to greatest turn all the numbers into decimal form.

[tex]\sqrt{7}[/tex]: 2.65

[tex]\sqrt{17}[/tex]: 4.12

[tex]\pi[/tex]: 3.14

4.6

2.8

Now order them from least to greatest (make sure you put the numbers back into their original form)

[tex]\sqrt{7}[/tex], 2.8, [tex]\pi[/tex], [tex]\sqrt{17}[/tex], 4.6

The numbers in the form of least to greatest will be [tex]\sqrt{7}[/tex], [tex]2\overline{.8}[/tex], π, [tex]\sqrt{17}[/tex], 4.6.

Rational numbers are those numbers which have terminating,Repeating or recurring digits after the decimal place.

Irrational numbers have non-repeating, non-recurring non-terminating digits after the decimal place.

According to the given question we have to order the number from least to greatest.

Given number are 4.6, [tex]2\overline{.8}[/tex], π, [tex]\sqrt{17}[/tex], [tex]\sqrt{7}[/tex].

We know the value of π is 3.14 approx and square root of 17 lies between square root of 16 and 25 which are 4 and 5 but more close to 4 and square root of 7 lies between square root of 4 and 9 which are 2 and 3.

∴  The given numbers in increasing order will be

[tex]\sqrt{7}[/tex], [tex]2\overline{.8}[/tex], π, [tex]\sqrt{17}[/tex], 4.6.

Step-by-step explanation:

3x - 13 = 23

Bring non-variable numbers to other side:

3x = 36

Divide both sides by 3:

x = 12

Answer:

x = 12

Step-by-step explanation:

This equation is very easy to solve.

3x - 13 = 23 Add 13 to both sides of the equation.

3x = 36 Divide by 3 on both sides of the equation.

x = 12

Then, check your answer by substituting the solved value.

3(12) - 13 = 23

36 - 13 = 23

23 = 23

Therefore, x = 12 is the solution to the equation.

Answer:

5x-2y=7

Answer:

11 cm, 11 cm

Step-by-step explanation:

Let the length and width of the rectangle be x cm and y cm respectively.

Therefore,

Perimeter of rectangle = 44 cm

2(x + y) = 44

x + y = 44/2

x + y = 22...... (1)

Area of rectangle = xy

When length is increased by 4 cm and breadth is increased by 2 cm.

New length = (x + 4) cm

New width = (y + 2) cm

New area of rectangle = original area + 72.. (given)

Therefore,

(x + 4) (y + 2) = xy + 72

xy + 2x + 4y + 8 = xy + 72

2x + 4y = 72 - 8

2x + 4y = 66

2(x + 2y) = 66

x + 2y = 66/2

x + 2y = 33.... (2)

Subtracting equation (1) from equation (2)

x + 2y - (x + y) = 33 - 22

x + 2y - x - y = 11

y = 11

Substituting y = 11 in equation (1)

x + 11 = 22

x = 22 - 11

x = 11

Thus, the dimensions of the rectangle are 11 cm and 11 cm.

Answer:

Mary has £20 and Tom has £16

Step-by-step explanation:

Represent their current respective money amounts by m and t.

Then m + t = £36, but also m/2 + 2t = £42.

Multiplying the second equation by 2 removes the fraction:

m + 4t = £84

and multiplying this by -1 results in

-m - 4t = -£84, which can now be added to the first equation m + t = £36:

-m - 4t = -£84

+m +  t  = £36

---------------------

       -3t =  -£48

We have successfully eliminated m.  To solve this last result for t, divide both sides by -3, obtaining t = £16

Since m + t  = £36 and t = £16, m must be £20.

Mary has £20 and Tom has £16
