Step-by-step explanation:

If you were to change the system into slope intercept you would get y=24+3x and -y=-24-3x. Then you would make the equation 24+3x=-24-3x. Then you would want to get all the variables on one side and the non variables on the other. Then you would get 48=-6x. From there you would divide -6x by -6 and get x. Then you do 48/-6 and get -8. So x=-8

The rate of change  is the same amount of meat from Thursday to Friday is 14 Kilograms of meat

Here, the line graph shows the amount of meat in kilograms fed to the lions on each day of the week.

From the line graph the amount of meat fed to the lines on Thursday is 58 kilograms

And the amount of meat fed to the lines on Thursday is 72 kilograms

Let x represents the rate of change in the amount of meat from Thursday to Friday.

So, the value of x would be,

x = 72 - 58

x = 14 kilograms

Thus, the rate of change in the same amount of meat are fed to the alliance between Thursday and Friday = 14 kilograms

The smallest possible total number of tokens in the jar is 27, with 6 red tokens, 3 white tokens, and 18 blue tokens.

Let's assume that the jar has "r" red tokens, "w" white tokens, and "b" blue tokens. Since the probability of selecting a red token and then a white token is the same as selecting a blue token, we can write the following equation

(r/3) × (w/3) = (b/3) × ((r + w)/3)

Simplifying this equation, we get

rw = b(r + w)

Now, we need to find the smallest possible total number of tokens in the jar. Since r, w, and b are all multiples of 3, we can write

r = 3x

w = 3y

b = 3z

Substituting these values in the equation rw = b(r + w), we get

9xy = 9z(x + y)

Simplifying this equation, we get

xy = z(x + y)

Since x, y, and z are all integers, we can say that z divides xy. Therefore, we can write

z = kd

xy = k(d x + d y)

where k and d are integers.

Now, we need to find the smallest possible value of (r + w + b) = 9(x + y + z) that satisfies the above conditions. Since z is a multiple of 3, we can start with k = 3. Also, we want to minimize (x + y + z), so we can start with d = 2. Substituting these values, we get

z = 3 × 2 = 6

xy = 3(2x + 2y) = 6(x + y)

The smallest possible values of x and y that satisfy this equation are x = 2 and y = 1. Substituting these values, we get

r = 3x = 6

w = 3y = 3

b = 3z = 18

Therefore, the smallest possible total number of tokens in the jar is

r + w + b = 6 + 3 + 18 = 27

Answer:

Step-by-step explanation:

Let the price for children and adults package be represented with x and y respectively.

For the first week the sum of the package will be as follows:

3x+8y = 126

For the two weeks after:

6x+4y= 108

So, we will be having two equations

3x+8y = 126..... (1)

6x+4y= 108.......(2)

These are simultaneous equations

From equation 1

3x+8y = 126

3x = 126-8y

X = 126-8y/3 ............. (3)

Put equation 3 into 2

6 ( 126-8y)/3 +4y = 108

756-48y/3 +4y = 108

756-48y+12y/3 = 108

Cross multiplying

756-48y+12y= 108×3

756-48y+ 12y = 324

Collecting like terms

756-324 = 48y-12y

432= 36y

Divide both sides by 36

432/36 = 36y/36

y= 12

Substituting y into equation 1

3x+8= 126

3x+96=126

3x= 126-96

3x= 30

Divide both sides by 3

3x/3 = 30/3

x = 10

Hence for each of the packages for children and adults. It will be 10 and 12 respectively.

Step-by-step explanation:

Yes, an angle in a right-angled triangle is always present.  Without any additional information about the triangle, it is impossible to determine the value of the angle in question.

In a right-angled triangle, one of the angles is a right angle, which measures 90 degrees. The other two angles in the triangle are acute angles and their measures always add up to 90 degrees.

To find the value of the angle in question, we need to know some additional information about the triangle. If we have the lengths of two sides of the triangle, we can use trigonometric ratios to find the measure of the angle.

For example, if we know the length of the side opposite the angle and the length of the hypotenuse (the longest side of the triangle), we can use the sine ratio to find the measure of the angle.

If we know the length of the side adjacent to the angle and the length of the hypotenuse, we can use the cosine ratio.

If 09 people can complete the job in 75 days then 25 people needs 45 days to complete the job.

Let T be the time and L be the Labor (Number of people working on the bridge).

T ∞ 1/√L  (Inverse relationship)

T = K/√L                   ----------------------------- (1)

Since, Constant "K" is introduced once the variation sign (∞) changes to equality (=) sign.

According to the question,

Time (T) = 75 days    and

labor (L) = 09

From the equation (1), we get,

    T = K / √L

⇒ 75   = K/√9

⇒ 75= K/3

⇒ K= 225

First, the relationship between these variables is:

                       T = 225/√L

Therefore, how long it will take 25 people to do it means that we should look for the time.

                           T=225/√L

                      ⇒  T= 225/√25

                      ⇒  T= 225/5

                      ⇒  T= 45 days.

therefore, 25 people needs 45 days to complete the job.

Step-by-step explanation:

Please see the attached picture for the full solution.

∠g and ∠h are complementary angles and ∠g and ∠h are acute angles are true statements from the given information

Two angles are given.

∠g = (2x-90)°

∠h = (180-2x)°

We have to find the statement which is true about the angles g and h.

If both angles are greater than zero.

Complementary angles add up to 90 degrees

i.e., ∠g and ∠h are complementary if ∠g + ∠h = 90°.

Substituting the given values:

∠g + ∠h

= (2x-90)° + (180-2x)° = 90°

Thus, ∠g and ∠h are complementary angles.

and both the angles are less than 90 degrees so we can tell that angles ∠g and ∠h  are acute.

So the statement ∠g and ∠h are acute angles is also true

Hence, ∠g and ∠h are complementary angles and ∠g and ∠h are acute angles are true statements

The final expression for differential of dy/dx is given by (4x³ - 4xy² - 6x(x² + y² - 1)) / (3(x² + y² - 1)² - 4y²).

Answer: We are given the equation (x² + y² - 1)³= 4x²y³and we are supposed to determine dy/dx by implicit differentiation.

First, we differentiate the given equation with respect to x using the chain rule (since the equation is in the form of f(g(x)), we get:

(3x² + 3y² - 2) * 2(x² + y² - 1) * 2x + (3x² + 3y² - 2)³ * 2y * dy/dx

= 8xy³ + 4x² * 3y² * dy/dx

Now, we can rearrange the equation to solve for dy/dx, which gives:

dy/dx = (4x³ - 4xy² - 6x(x² + y² - 1)) / (3(x² + y² - 1)² - 4y²)

Therefore, we have: dy/dx = (4x³ - 4xy² - 6x(x² + y² - 1)) / (3(x² + y² - 1)² - 4y²)

Thus, the required derivative is (4x³ - 4xy² - 6x(x² + y² - 1)) / (3(x² + y² - 1)² - 4y²).

Conclusion:

Therefore, the final expression for dy/dx is given by (4x³ - 4xy² - 6x(x² + y² - 1)) / (3(x² + y² - 1)² - 4y²).

Answer:

2.4cm

Step-by-step explanation:

the area of a triangle is

baseline × height / 2

that means two lengths of the triangle have to be multiplied.

and to have 2 similar triangles means that all lengths inside one triangle are the corresponding lengths inside the other triangle multiplied by the scaling factor f.

multiplying 2 if these lengths with each other means also including the square of the scaling factor (multiplying with the scaling factor twice).

so, if the area of triangle 1 is

"baseline 1" × "height 1" / 2 = 45 cm²

then the area of triangle 2 is

"baseline 2" × "height 2" / 2 =

= "baseline 1"×f × "height 1"×f /2 =

= "baseline 1" × "height 1" × f² / 2 =

= ("baseline 1" × "height 1" / 2) × f² =

= 45 × f² = 20 cm²

f² = 20/45 = 4/9

f = 2/3

so, for a side of ABC being 3.6cm long, that means the corresponding side in DEF is

3.6 × f = 3.6 × 2/3 = 7.2/3 = 2.4cm

Answer:

m = 2 and n = -10

Step-by-step explanation:

The given function is f(x) = x² + 4·x - 6

The form in which f(x) is to be written = (x + m)² + n, which is the standard form of a quadratic equation

We have;

f(x) = x² + 4·x - 6 = x² + 4·x + 4 - 6 - 4

f(x) = x² + 4·x + 4 - 6 - 4 = (x + 2)² - 10

f(x) = (x + 2)² - 10

By comparison with (x + m)² + n, we have;

m = 2, and n = -10

The simplified form of the complex fraction (1/2) / (2/y) is y/4.

A complex fraction is a fraction in which either the numerator, the denominator, or both contain fractions. In other words, it is a fraction that has one or more fractions within it.

Complex fractions are written in the form:

(a/b) / (c/d)

where a, b, c, and d are numbers, and b, c, and d are not equal to zero.

To simplify a complex fraction, we can convert it into a simpler form by following a few steps.

1: Invert the denominator of the inner fraction.

(1/2) / (2/y) becomes (1/2) * (y/2).

2: Multiply the numerators and denominators.

(1/2) * (y/2) = (1 * y) / (2 * 2) = y/4.

By multiplying the numerators and denominators, we get the simplified complex fraction y/4.

In this case, the complex fraction (1/2) / (2/y) simplifies to y/4, where y is a non-zero number.
