Answer:

22 rabbits and 50 hens

Step-by-step explanation:

Let H and R stand for the numbers of Hens and Rabbits.  Each hen has two feet and each rabbit has four feet.  Each only has 1 head.

We can set the quantities of feet and heads:

Hens:  2H feet and 1H heads

Rabbits:  4R feet and 1R heads

We are told that:

1.)  "The number of feet of the hens exceeds the number of feet of the rabbits by 12"  Rewrite this as an expression:

  2H - 4R = 12  [feet]

2)  "while the number of heads of the hens exceeds the number of the heads of the rabbits by 28"  This is written as:

  1H = 1R + 28  [heads]

Since each critter only has one head, this last expression will tell us, quickly, how many more Hens there are, which is 28.  But by substituting the first expression (the feet) into the second, we can detrermine the exact number of each animal.

Rearrange 2H - 4R = 12 to isolate one of the variables.  I'll choose H:

  2H - 4R = 12

  2H  = 12 + 4R

  H  = (12 + 4R)/2

   H =  6+2R

Now use this definition of H in the second equation:

1H = 1R + 28

1(6+2R) = 1R + 28

6 + 2R = 1R + 28

 R = 22   There are 22 rabbits

Use this in the second equation to find the number of hens:

1H = 1R + 28

1H = 22 + 28

 H = 50  There are 50 hens.

=================

Check:

1.)  "The number of feet of the hens exceeds the number of feet of the rabbits by 12."  

 Hens have 100 feet total.  Rabbits have 88 feet.    The hens have 12 more total feet:  This checks

2.)  "while the number of heads of the hens exceeds the number of the heads of the rabbits by 28"  

 There are 50 heans and 22 rabbits.  The number of hen heads exceed the number of rabbit heads by 28.  This also checks.

What is the linear equation?

A linear equation is an algebraic equation of the form y=mx+b, where m is the slope and b is the y-intercept, and only a constant and a first-order (linear) term are present. The variables in the above equation are y and x, and it is occasionally referred to as a "linear equation of two variables."

let's take the weight of five boys is x

so,

x/5 = 62

x = 310

and let's take the weight of four boys is y.

so,

y/4 = 64

y = 256

let's take the weight of a boy which is removed from them is z

so,

x - z = y

x - y = z

310 - 256 = z

z = 54

Hence, the mass of the boy removed is 54.

The value of the variable 'y' will be 3. Then the correct option is A.

The allocation of weights to the important variables that produce the calculation's optimum is referred to as a direct consequence.

The system of the linear equation is given below.

2x - 5y = 1                ...1

-3x + 2y = - 18         ...2

Multiply equation 1 by 2 and equation 2 by 5, then we have

4x - 10y = 2

-15x + 10y = - 90

Add both equations, then we have

4x - 15x = 2 - 90

11x = 88

x = 8

Then the value of the variable 'y' is calculated as,

-3 (8) + 2y = - 18

- 24 + 2y = - 18

2y = 24 - 18

2y = 6

y = 3

The worth of the variable 'y' will be 3. Then the right choice is A.

Answer:

Q14    x = 3

Q15    No unique solution

Step-by-step explanation:

Q14

The value of x where the line crosses the x axis is the solution for x

Here we see the line crosses the x axis at x = 3 so solution is x =3

Mathematically,

2x - 3 = 3

2x = 3 + 3  adding 3 to both sides

2x = 6

x = 6/2 = 3

Q15

This is a horizontal line which crosses the y-axis at y = 1

Since this does not cross the x axis but is parallel to it, there is no unique solution for x

Mathematically,
-4x + 2 = -4x + 1

Adding 4x to both sides we get the absurdity that 2 = 1 and that indicates no unique solution for x. Alternatively we can say that x has an infinite number of solutions

The segments that could be the image of segment AB after a sequence of reflections, rotations, and/or translations include:

A. Line segment GH

D. Line segment NP

F. Line segment CD

From the information, the coordinates of the point A is (1, 2), the coordinates of the point B is (5, 2)

Therefore, the length of the line AB = 5 - 1 = 4 units

In this case, the transformations are, reflections, rotations, and/or translations which are rigid transformations, such that the length of the image of AB will be the same as the length of AB

Therefore, the possible images of AB are;

PN with coordinates P(5, -2) and N(9, -2) and length 9 - 5 = 4 units

HG with coordinates H(-4, -4) and G(-4, -8) and length -4 - (-8) = -4 + 8 = 4 units

Answer:

  (b)  g(x) = 6√x +7

Step-by-step explanation:

You want the equation of the square root function after it has been vertically stretched by a factor of 6 and translated up 7 units.

A vertical stretch is accomplished by multiplying the function value by 'a', where 'a' is the vertical stretch factor. That means the stretched square root function will be ...

  f(x) = √x . . . . original square root function

  h(x) = 6·f(x) = 6√x . . . . . vertically stretched by a factor of 6

A translation upward is accomplished by adding the translation amount to the function value. The translated function will be ...

  h(x) . . . . . original function

  g(x) = h(x) +7 . . . . . translation upward by 7 units

Our stretched and translated function is ...

Step-by-step explanation:

Answer:   -4608

========================================================

Explanation:

a = 9 = first term

r = -2 = common ratio

We multiply each term by -2 to generate the next term

The nth term for this geometric sequence is a*(r)^(n-1) which becomes 9(-2)^(n-1)

If you tried plugging in say n = 2, you should find that,

9(-2)^(n-1)

9(-2)^(2-1)

9(-2)^1

9(-2)

-18

So that confirms the second term. I'll let you try the other values of n to confirm it further.

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

From here, you plug in n = 10 to find the tenth term

9(-2)^(n-1)

9(-2)^(10-1)

9(-2)^9

9(-512)

-4608

Step-by-step explanation: To solve this inequality, we can first isolate the absolute value term on one side of the inequality by subtracting |n-2| from both sides of the inequality. This gives us the inequality -3 + |n-2| > 2. Then, we need to consider two cases: when |n-2| is positive and when |n-2| is negative.

If |n-2| is positive, then we can drop the absolute value bars and rewrite the inequality as -3 + (n-2) > 2. Solving this inequality, we find that n > 7.

If |n-2| is negative, then we must reverse the direction of the inequality because subtracting a negative number is the same as adding a positive number. This gives us the inequality -3 - (n-2) > 2. Solving this inequality, we find that n < -1.

Therefore, the solution to the inequality is the set of all numbers that are greater than 7 or less than -1, which is the interval (-1, 7).

x² - 8x + 5 can be expressed as (x - 4)² - 11 in the form (x - a)² - b, where a = 4 and b = 11.

Let y = x² - 8x + 5 ..................( 1 )

Expanding (x - a)² - b we get,

x² - 2ax + a² - b ......................( 2 )

Equating ( 1 ) and (2), we get

x² - 8x + 5 = x² - 2ax + a² - b

Comparing the coefficient of x,

- 8  =  - 2a

a = 4

Comparing constants,

a² - b =  5

since we know a = 4

4² - b =  5

16 - b =  5

b = 11

Hence x² - 8x + 5  = (x - 4)² - 11

The equation of the required line is given as y = -23x - 92.

A straight line can be written in the form of equation as, y = mx + c.

Two straight lines intersect each other only at one point.

When two straight lines are parallel to each other the angle between them is zero.

The given problem can be solved as follows,

The equation of the line is  y = −23x + 32.

Then, its slope is given by -23.

Since the parallel lines have the same slope, the slope of the line parallel to  y = −23x + 32 is -23.

Now, the equation of the line passing through (4, -7) and parallel to the given line can be written as,

(y + 7)/(x - 4) = -23

=> y + 7 = -23x - 92

=> y = -23x + -99

=> y = -23x - 92

Hence, the equation of the line passing through (4, -7) and parallel to y = −23x + 32 is  y = -23x - 92.

x + y = 63

2.25x + 3y = 159

From (1)

x = 63 - y

Substitute into (2)

2.25x + 3y = 159

2.25(63 - y) + 3y = 159

141.75 - 2.25y + 3y = 159

0.75y = 17.25

divide both sides by 0.75

y = 17.25 / 0.75

y = 23

Substitute y = 23 into (1)

x + y = 63

x + 23 = 63

subtract 23 from both sides

x = 63 - 23

x = 40
