Step-by-step explanation:

We substitute -1+1/6y for x in the second equation (bottom equation) in order to solve the system by the substitution method.

The given system of equations are 2x-1/3y = -2...(1)

3x+y=1...(2)

We solve this system of equations by using substitution method.

Let us solve for x in equation to substitute it in equation (2).

2x=-2+1/3y

Divide both sides of equation by 2.

x=-1+1/6y

Now plug in the value of x in equation 2.

Hence, we substitute -1+1/6y for x in the second equation (bottom equation) in order to solve the system by the substitution method.

The turning points of the function y = x³ - 3x² - 9x + 4 are (3, -23) and (-1, 9).

To determine the turning points of the given function y = x³ - 3x² - 9x + 4, we need to find the critical points where the derivative of the function is equal to zero.

1. Find the derivative of the function:

  y' = 3x² - 6x - 9

2. Set the derivative equal to zero and solve for x:

  3x² - 6x - 9 = 0

3. Factorize the quadratic equation:

  3(x² - 2x - 3) = 0

4. Solve the quadratic equation by factoring or using the quadratic formula:

  (x - 3)(x + 1) = 0

  This gives us two possible values for x: x = 3 and x = -1.

5. Substitute these critical points back into the original function to find the corresponding y-values:

  For x = 3:

  y = (3)³ - 3(3)² - 9(3) + 4

    = 27 - 27 - 27 + 4

    = -23

  For x = -1:

  y = (-1)³ - 3(-1)² - 9(-1) + 4

    = -1 - 3 + 9 + 4

    = 9

6. Therefore, the turning points are (3, -23) and (-1, 9).

Note: It appears that there was a typo in the original equation, where the term "-9x" should have been "-3x²". The above solution assumes the corrected equation.

Answer:

The Commutative property is represented by 5 + (-8) = -8 + 5.

Step-by-step explanation:

We are the following the following expression below;

5 + (-8) = -8 + 5

This property says that is any number is added to 0, then the result is the number itself, i.e.;

2 + 0 = 2 or (-7) + 0 = -7.

Suppose there are three numbers; a, b and c.

So, this property hold the condition that; a + (b + c) = (a + b) + c

If we add the second and third numbers and then add the first number to it or if we add the first and second numbers and then add the third number to it, the result will be the same.

Suppose there are two numbers 6 and 8.

This property states that if we add 6 + 8 or 8 + 6, both are equal, i,e;

6 + 8 = 8 + 6

14 = 14.

This property states the following condition;

a \(\times\) (b + c) = (a \(\times\) b) + (a \(\times\) c)

So, 5 + (-8) = -8 + 5 is represented by the commutative property.

The probability of drawing a king from a standard deck of 52 cards is 1/13.

In a standard deck of 52 playing cards, there are four kings: the king of hearts, the king of diamonds, the king of clubs, and the king of spades.

To find the probability of drawing a king, we need to determine the ratio of favorable outcomes (drawing a king) to the total number of possible outcomes (drawing any card from the deck).

The total number of possible outcomes is 52 because there are 52 cards in the deck.

The favorable outcomes, in this case, are the four kings.

Therefore, the probability of drawing a king is given by:

Probability = (Number of favorable outcomes) / (Number of possible outcomes)

= 4 / 52

= 1 / 13

Thus, the probability of drawing a king from a standard deck of 52 cards is 1/13.

This means that out of every 13 cards drawn, on average, one of them will be a king.

It is important to note that the probability of drawing a king remains the same regardless of any previous cards that have been drawn or any other factors.

Each draw is independent, and the probability of drawing a king is constant.

Answer:

Option (D)

Step-by-step explanation:

We will use the property of perpendicular lines to solve this question.

If the two lines having slopes \(m_1\) and \(m_2\) are perpendicular,

\(m_1\times m_2=-1\)

Given lines are,

Option (A).

y = 4x - 6

\(m_1=4\)

y = 4x + 11

\(m_2=4\)

\(m_1\times m_2=16\)

Lines are not the perpendicular lines.

Option (B).

y = -4x - 6

\(m_1=-4\)

y = 4x + 11

\(m_2=4\)

\(m_1\times m_2=-16\)

Lines are not perpendicular.

Option (C).

y = \(\frac{1}{4}x-6\)

\(m_1=\frac{1}{4}\)

y = 4x + 11

\(m_2=4\)

\(m_1\times m_2=1\)

Therefore, lines are not perpendicular.

Option (D).

y = \(-\frac{1}{4}x-6\)

\(m_1=-\frac{1}{4}\)

y = 4x + 11

\(m_2=4\)

\(m_1\times m_2=-1\)

Therefore, both the lines are perpendicular.

Option (D) is the answer.

Since the product of their slope is -1, hence the equation y = -1/4 x - 6 and y = 4x + 11 are perpendicular. Option D is correc.=t

For two lines to be perpendicular, the product of their slope must be -1.

The standard equation of a line in slope-intercept form is expressed as

y = mx +b

m is the slope

b is the y-intercept

Check the option D,

For the equation y = -1/4 x - 6, the slope is -1/4

For the equation y = 4x + 11, the slope is 4

Taking the product of their slope;

Product = -1/4 * 4

Product  = -1

Since the product of their slope is -1, hence the equation y = -1/4 x - 6 and y = 4x + 11 are perpendicular

The equation that represents the situation is a = b- 4.

Since the plant grows at a constant rate, we can assume that the height of the plant is increasing linearly with time.

Let's use the data from Week 1 and Week 2 to find the rate of growth for each plant:

For Plant A: Growth rate = (24 cm - 22 cm) / (2 weeks - 1 week) = 2 cm/week

For Plant B: Growth rate = (28 cm - 26 cm) / (2 weeks - 1 week) = 2 cm/week

Since the growth rate is constant, we can use the equation of a line to model the height of each plant over time:

For Plant A: a = 2t + b, where t is the time in weeks and b is the initial height of the plant.

For Plant B: b = 2t + c, where c is the initial height of Plant B.

We can find the values of b and c by substituting the data from Week 1 into these equations:

For Plant A: 22 = 2(1) + b, so b = 20.

For Plant B: 26 = 2(1) + c, so c = 24.

Now we can substitute these values into the equations for Plant A and Plant B:

Plant A: a = 2t + 20

Plant B: b = 2t + 24

To find an equation that gives Plant A's height in terms of Plant B's height, we can solve the equation for t in terms of b:

b = 2t + 24

2t = b - 24

t = (b - 24) / 2

Then we can substitute this expression for t into the equation for Plant A:

a = 2t + 20

a = 2[(b - 24) / 2] + 20

a = b - 24 + 20

a = b - 4

So the equation we were looking for is:

a = b - 4

Therefore, to find Plant A's height in centimeters given Plant B's height in centimeters, we simply subtract 4 from Plant B's height.

Answer: Therefore, the population will exceed 100,000 in the year 2005 + 10.73 ≈ 2016.

Step-by-step explanation:   a) The population of the town in 2005 is given by the formula, where t = 0 since 2005 is the starting year:

P = 50,000(1.15)^0 = 50,000

Therefore, the population of the town in 2005 was 50,000.

b) We need to find the value of t when the population P exceeds 100,000:

100,000 = 50,000(1.15)^t

Divide both sides by 50,000:

2 = 1.15^t

Take the natural logarithm of both sides:

ln 2 = ln (1.15^t)

Apply the power rule of logarithms:

ln 2 = t ln 1.15

Divide both sides by ln 1.15:

t = ln 2 / ln 1.15

Using a calculator, we get:

t ≈ 10.73

The linear equation satisfying the given condition is,

\(x=t+15\)

where x is Ravi's age and t is the number of years

(after 10 years (t=10) his age becomes 25)

Step-by-step explanation:

Let x be Ravi's age

Now, his  current age is unknown, but if you add 10 to it, then it becomes 25, so

x + 10 =25

so, his current age is x = 25 =10

x = 15

Now, we find the linear equation satisfying the given condition,

Let t be the number of years that have passed since the present time

so, if 0 years have passed, his age will be 15 years

after 1 year, his age will be 16 years

after 10 years, his age will be 25 years and so on

so

\(x = t + 15\)

this satisfies the given condition, since if we add ten years i.e t = 10,

then we get 25

The equation is:

Work/explanation:

Here's the linear equation for Ravi's age.

Ravi's age is x.

If you add 10 to x you get x + 10.

That gives 25.

So the linear equation is x + 10 = 25.

An indefinite integral is a function that, when differentiated, equals the original function. It is denoted by ∫f(x)dx, where f(x) is the function to be integrated. An indefinite integral always has an arbitrary constant of integration, which is denoted by C. This is because the derivative of any constant is zero, so the derivative of ∫f(x)dx+C is still equal to f(x).

A definite integral is the limit of a Riemann sum as the number of terms tends to infinity. It is denoted by ∫

a

b

​

f(x)dx, where a and b are the limits of integration. A definite integral does not have an arbitrary constant of integration, because the limits of integration specify a unique value for the integral.

25, 12, 13

18, 2, 24

The set of side measurements 3, 1, 5 could not form a triangle.

To determine which set of side measurements could form a triangle, we need to check if the sum of the lengths of the two shorter sides is greater than the length of the longest side. This is known as the Triangle Inequality Theorem.

Let's check each set of side measurements:

13, 19, 7:

The sum of the two shorter sides is 7 + 13 = 20, which is greater than the longest side (19). Therefore, this set of side measurements could form a triangle.

25, 12, 13:

The sum of the two shorter sides is 12 + 13 = 25, which is equal to the longest side (25). Therefore, this set of side measurements could form a triangle.

18, 2, 24:

The sum of the two shorter sides is 2 + 18 = 20, which is greater than the longest side (24). Therefore, this set of side measurements could form a triangle.

3, 1, 5:

The sum of the two shorter sides is 1 + 3 = 4, which is less than the longest side (5). Therefore, this set of side measurements could not form a triangle.

Based on the Triangle Inequality Theorem, the sets of side measurements that could form a triangle are:
