Answer:

The money receive by Paul is  [tex]\pounds 40[/tex].

Step-by-step explanation:

Given as :

The ratio of share of money among three people as

Stephen : Paul : Bridget = 3 : 4 : 2

The total money receive by Stephen and Bridget = [tex]\pounds 50[/tex]

Let The money receive by Stephen = 3 x

Let The money receive by Paul = 4 x

Let The money receive by Bridget = 2 x

Now, According to question

The total money receive by Stephen and Bridget = [tex]\pounds 50[/tex]

I.e 3 x + 2 x =  [tex]\pounds 50[/tex]

i.e 5 x =  [tex]\pounds 50[/tex]

∴    x = [tex]\frac{\pounds 50}{5}[/tex]  

    x =  [tex]\pounds 10[/tex]

So, The money receive by Stephen = 3 × [tex]\pounds 10[/tex] = [tex]\pounds 30[/tex]

Let The money receive by Paul = 4 × [tex]\pounds 10[/tex] = [tex]\pounds 40[/tex]

Let The money receive by Bridget = 2 × [tex]\pounds 10[/tex] = [tex]\pounds 20[/tex]

Hence The money receive by Paul is  [tex]\pounds 40[/tex]. Answer

Answer:

x=1,2

Step-by-step explanation:

we show that 4x is <12

if x=1,,,4x=4*1=4

if x=2,,,4x=4*2=8

if x=3,,,4x= 4*3=12

so 1 &2 is right ans

[tex](f o g)(x) = 245x^2+6\\(g o f)(x) = 5x^2+42\\ f(g(-4)) = 3926\\g(f(5)) = 917[/tex]

Step-by-step explanation:

Given

[tex]f(x) = 5x^2+6\\g(x) = 7x[/tex]

So

[tex](f o g)(x) = 5(7x)^2+6\\= 5(49x^2)+6\\=245x^2+6\\(g o f)(x) = 7(5x^2+6)\\= 35x^2+42\\(fog(x))=245x^2+6f(g(-4)) = 245(-4)^2+6 \\=245(16)+6\\=3920+6\\=3926\\g(f(x)) = 35x^2+42\\g(f(5)) = 35(5)^2+42\\=35(25)+42\\=875+42\\=917[/tex]

Hence,

[tex](f o g)(x) = 245x^2+6\\(g o f)(x) = 5x^2+42\\ f(g(-4)) = 3926\\g(f(5)) = 917[/tex]

The same solution of the given system of equations will be same as the solution of below system of equations;

⇒ 8x + 4y = −4

17x + 2y = −28

Option A is true.

What is an expression?

Mathematical expression is defined as the collection of the numbers variables and functions by using operations like addition, subtraction, multiplication, and division.

Given that;

The System of equation is,

6x + 2y = - 6   ..(i)

3x - 4y = - 18   ..(ii)

Now,

Solve the given system of equation as;

The System of equation is,

6x + 2y = - 6   ..(i)

3x - 4y = - 18   ..(ii)

By equation (i);

6x + 2y = - 6  

2(3x + y) = - 6

3x + y = - 3  ..(iii)

Subtract equation (ii) from (iii), we get;

3x - 4y - (3x + y) = - 18 - (-3)

3x - 4y - 3x - y = - 18 + 3

- 5y = - 15

y = 3

And, By equation (i), we get;

6x + 2y = - 6  

6x + 2 × 3 = - 6

6x + 6 = - 6

6x = - 6 - 6

6x = - 12

x = - 2

Thus, The solution of given system of equation are;

x = - 2 and y = 3

Now,

Substitute the value of x and y in all the given options and find the same solution of given system of equation as;

A: 8x + 4y = −4

17x + 2y = −28

Substitute the value of x = - 2 and y = 3;

8x + 4y = −4

8 × - 2 + 4 × 3 = - 4

- 16 + 12 = - 4

- 4 = - 4

17x + 2y = −28

17 × - 2 + 2 × 3 = - 28

- 34 + 6 = - 28

- 28 = - 28

Thus, This system of equation has same solution.

Therefore, The same solution of the given system of equations will be same as the solution of below system of equations;

⇒ 8x + 4y = −4

17x + 2y = −28

Option A is true.

Answer:

1; solution is not extraneous

Step-by-step explanation:

the value 3=3 is true, meaning its not extraneous and also I got it correct on the test

The value of x is 1, and the solution is not extraneous.

Given that,

Equation; [tex]\sqrt{3x+6 } = 3[/tex]

We have to determine,

The value of x and identify if it is an extraneous solution.

According to the question,

Equation; [tex]\sqrt{3x+6 } = 3[/tex]

To find the value of the x following all the steps given below.

Squaring both the sides to solve the equation,

[tex]\sqrt{3x+6 } = 3\\\\(\sqrt{3x + 6 })^2= 3^2\\\\3x + 6 = 9\\\\3x = 9-6\\\\3x = 3\\\\x = \dfrac{1}{1}\\\\x = 1[/tex]

An extraneous solution is a root of a transformed equation that is not a root of the original equation.

Therefore, The solution is not extraneous.

Hence, The value of x is 1, and the solution is not extraneous.

The Graph that represents the inverse of function f is attached below.

Function is a type of relation, or rule, that maps one input to specific single output.

We have been given a function of x as; f(x) = 2x - 2

If function 'f' is one-to-one and onto function (a needed condition for inverses to exist), then, the inverse of the considered function is

y = 2x - 2

x = 2y - 2

x + 2 = 2y

y = (x + 2)/2

Answer:

473 turnips

Step-by-step explanation:

well if its 1 to 1 that means how ever meany you have of one you will have the same exact amount of the other food

473x1 = 473x1

Final answer:

To find the number of turnips, set up a proportion using the given ratio and cross multiply to solve for the number of turnips.

Explanation:

To find the number of turnips, we can set up a proportion using the given ratio:
Number of potatoes / Number of turnips = Ratio of potatoes to turnips.
Since the ratio of potatoes to turnips is 1:1, the proportion will be:
473 / Number of turnips = 1 / 1.

To solve for the number of turnips, cross multiply:
473 * 1 = Number of turnips * 1.
Number of turnips = 473.

Therefore, there are 473 turnips in this scenario.

Answer:

361 sq, inches.

Step-by-step explanation:

Let us assume that the dimensions of the square picture are P in × P in.

So, the area of the picture alone is, A = P²

Now, if the photo has a frame of 1 inch wide, then the dimensions of the photo with frame are (P + 2) in × (P + 2) in.

So, the area of the photo with frame is A' = (P + 2)(P + 2) = (P + 2)²

Now, the area of the frame alone is 80 sq. inches.

Hence, A' - A = 80

⇒ (P + 2)² - P² = 80

⇒ 4P + 4 = 80

⇒ 4P = 76

⇒ P = 19 inches.

So, the area of the picture is = 19² = 361 sq. inches. (Answer)

x = 1240-y can be used to model the situation where x is the amount earned in second week.

Step-by-step explanation:

Given,

Total amount earned = D =  $1240

Amount earned in first week = y = $480

Let,

x be the amount earned in second week.

Therefore,

Total amount earned = Amount earned in 1st week + 2nd week amount

D = x + y

1240 = x + y

Solving for x;

[tex]x= 1240- y [/tex]

x = 1240-y can be used to model the situation where x is the amount earned in second week.

Answer:

Nancy needs to order 5 boxes of travoprost and 9 boxes of latanoprost for her pharmacy.

Step-by-step explanation:

Nancy counts 10 boxes of travoprost and the pharmacy needs 15 boxes to maintain a minimal level in the stock.

So, there is a need to order (15 - 10) = 5 boxes of travoprost.

Again, Nancy counts 3 boxes of latanoprost and the pharmacy needs to 12 boxes.  

So, there is a need to order (12 - 3) = 9 boxes of latanoprost.

Therefore, Nancy needs to order 5 boxes of travoprost and 9 boxes of latanoprost for her pharmacy. (Answer)

Final answer:

Nancy needs to order 5 boxes of travoprost and 9 boxes of latanoprost to fulfill the pharmacy's minimal stock requirement.

Explanation:

Nancy needs to order more boxes of eye medication to meet the pharmacy's minimal stock levels. For travoprost, the pharmacy requires 15 boxes but currently has only 10 boxes. So, Nancy needs to order:

15 boxes (required amount) - 10 boxes (current amount) = 5 boxes of travoprost.

For latanoprost, the pharmacy needs 12 boxes, but only has 3 boxes in stock, meaning Nancy needs to order:

12 boxes (required amount) - 3 boxes (current amount) = 9 boxes of latanoprost.

Answer:

Option B. a = −5, b = −9, c = 12

Step-by-step explanation:

The general form of the quadratic equation is as following

ax² + bx + c = 0

Where a, b and c are constants.

And the given equation is −5x2 − 9x + 12 = 0

Comparing the given equation to the general form

  ax² + bx + c = 0

−5x2 − 9x + 12 = 0

So, a = -5  , b = -9  and   c = 12

Identifying the values a, b, and c is the first step in using the Quadratic Formula to find solution(s) to a quadratic equation.

So, the answer is option B: a = −5, b = −9, c = 12
