The measure of angle x in the hexagon is 140 degree.

The formula for calculating the sum of interior angles of a polygon is ( n − 2 ) × 180 degree.

where is the number of sides

Since the number of sides of the polygon in the diagram is 6, we can find the sum of the interior angle.

Sum of interior angle = ( n − 2 ) × 180

Plug in n = 6

Sum of interior angle = ( 6 − 2 ) × 180

Sum of interior angle = ( 4 ) × 180

Sum of interior angle = 720°

Next, we sum up the interior angles given in the diagram equate to 720 degree and solve for x.

108 + 155 + 123 + 104 + 90 + x = 720

Collect and add like terms

580 + x = 720

Subtract 580 from both sides

580 - 580 + x = 720 - 580

x = 720 - 580

x = 140°

Therefore, the value of x is 140 degree.

What is the system of equations?

A finite set of equations for which common solutions are sought is referred to as a set of simultaneous equations, often known as a system of equations or an equation system.

Let's look at the first one, we can rewrite it as:

y = 2x + 3

y = -x - 3

So, the slopes are different, meaning that we have one solution, so this system is consistent and independent.

Now let's look at the second system, we can rewrite it as:

y = 3x - 2

y = 3x + 2

Here both lines have the same slope, so the lines never do intersect, meaning that the system is inconsistent and independent.

For the final system, we have:

y = (-1/2)×x + 2

y = (-1/2)×x + 2

Hence, we have two equal lines, so this system is dependent.

What are algebraic equations?

An algebraic equation is a mathematical expression that includes one or more variables and mathematical operations such as addition, subtraction, multiplication, and division. The equation asserts that two expressions are equal.

The goal in solving an algebraic equation is to determine the value(s) of the variable(s) that make the equation true. Algebraic equations are used to solve problems in various fields such as physics, engineering, economics, and finance.

In the equation 3s + 135 = 4.5(s + 10), the expression (s + 10) represents the total number of rolls sold (small and large).

To see why, let's break down the equation:

3s represents the total amount earned from selling small rolls (since the

club earns $3.00 for every small roll sold).

4.5(s + 10) represents the total amount earned from selling all the rolls (small and large). The (s + 10) part represents the total number of rolls sold, since the club sold 10 more large rolls than small rolls, which is represented by adding 10 to the number of small rolls sold (s).

Therefore, the correct answer is (C) the total number of rolls sold (small and large).

The required final amount and interest are 3311.05 and 311.05

When you make interest on both the money you've saved and the interest you've earned, this is known as compound interest.

A. To find the amount of money in the account after 5 years, we can use the formula for compound interest:

[tex]$$A = P \left(1 + \frac{r}{n}\right)^{nt}$$[/tex]

where A is the final amount, P is the principal, r is the annual interest rate (as a decimal), n is the number of times the interest is compounded per year, and t is the number of years.

In this case, P = $3000, r = 0.02 (2%), n = 4 (compounded quarterly), and t = 5. Plugging in these values, we get:

[tex]$$A = 3000\left(1 + \frac{0.02}{4}\right)^{4\cdot5} \approx $3311.05$$[/tex]

Therefore, there will be approximately 3311.05 in the account after 5 years.

B. To find the interest earned, we can subtract the principal from the final amount:

[tex]$$I = A - P = $3311.05 - $3000 = $311.05$$[/tex]

Using basic arithmetic operation, Ann's stock investment has increased in value more, by $331.25, compared to her bond investment, which has increased in value by $378.66.

The current value of Ann's bond investment can be calculated using the following formula:

Current Value of Bonds = Par Value x Market Rate

Since Ann has 7 bonds with a par value of $500 each, the total par value of her bond investment is:

$500 x 7 = $3,500

Using the market rate of 106.384, we can calculate the current value of Ann's bond investment as:

Current Value of Bonds = $3,500 x 1.06384 = $3,725.44

The current value of Ann's stock investment can be calculated by multiplying the number of shares she owns by the current stock price:

Current Value of Stock = Number of Shares x Stock Price

Since Ann owns 125 shares of Cilla Shipping stock and the current stock price is $30.65, the current value of her stock investment is:

Current Value of Stock = 125 x $30.65 = $3,831.25

To determine which investment has increased in value more, we need to compare the difference between the current and original values of each investment. The original value of Ann's bond investment is:

Original Value of Bonds = Par Value x Market Rate = $500 x 7 x 0.95626 = $3,346.78

The difference between the current and original value of Ann's bond investment is:

$3,725.44 - $3,346.78 = $378.66

The original value of Ann's stock investment is:

Original Value of Stock = Number of Shares x Stock Price = 125 x $28.00 = $3,500

The difference between the current and original value of Ann's stock investment is:

$3,831.25 - $3,500 = $331.25

Hence, Ann's stock investment has increased in value more, by $331.25, compared to her bond investment, which has increased in value by $378.66.

Answer:

To find the scale of the photograph, we need to determine the ratio between the actual height of the man and the height of the man in the photograph.

First, we convert the height of the man from feet to inches:

6 feet = 6 x 12 = 72 inches

Next, we can set up a proportion:

actual height of man / height of man in photograph = scale factor

Substituting the given values, we get:

72 inches / 1.5 inches = scale factor

Simplifying, we get:

scale factor = 48

Therefore, the scale of the photograph is 1:48, which means that one inch in the photograph represents 48 inches (or 4 feet) in real life.

The opposite of squaring an integer is finding its square root. The result of multiplying a number by itself yields its square value, whereas the square root of a number may be found by looking for a number that, when squared, yields the original value. The equation a a = b is true if 'a' is the square root of 'b'. Every integer has two square roots, one of a positive value and one of a negative value, because the square of any number is always a positive number. For instance, the square roots of 4 are both 2 and -2.

The probability is approximately 0.8185 or 81.85%.

Normal distribution, also known as Gaussian distribution, is a probability distribution that is commonly used in statistics, mathematics, and the natural sciences to describe real-valued random variables whose distributions are not known.

To find the probability that a randomly selected x-value from a normal distribution with a mean of 48 and a standard deviation of 7 is between 34 and 55, we need to standardize the values using the z-score formula:

z = (x - μ) / σ

where x is the value we want to find the probability for, μ is the mean, and σ is the standard deviation.

For x = 34:

z = (34 - 48) / 7 = -2

For x = 55:

z = (55 - 48) / 7 = 1

We can use a standard normal distribution table or a calculator to find the area under the standard normal distribution curve between z = -2 and z = 1. This area represents the probability that a randomly selected x-value from the given normal distribution is between 34 and 55.

Using a standard normal distribution table, we can find the probabilities as follows:

P(z < -2) = 0.0228 (from the table)

P(z < 1) = 0.8413 (from the table)

Therefore, the probability that a randomly selected x-value from the given normal distribution is between 34 and 55 is:

P(-2 < z < 1) = P(z < 1) - P(z < -2) = 0.8413 - 0.0228 = 0.8185

Explanation:

Problem 1

Each time x goes up by 1, y goes down by 5. This constant rate of change leads to the equation being linear. The slope is m = -5/1 = -5. You can use the slope formula for any two points in the table to confirm this is the correct slope.

The y intercept is b = 15 because we have x = 0 lead to y = 15.

Therefore, we go from y = mx+b to y = -5x+15

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

Problem 2

Each time x goes up by 3, the y coordinate goes down by 3. Therefore, we have another linear equation here. The slope is m = -3/3 = -1.

The y intercept is b = 4 because x = 0 leads to y = 4.

y = mx+b turns into y = -x+4

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

Problem 3

Each time x goes up by 1, y is NOT going up the same amount. The jump from 10 to 20 is +10. The jump from 20 to 40 is +20. And so on.

Therefore, this equation isn't linear. Instead it's exponential. Each y term doubles when x increases by 1, so that's why the b term is b = 2.

The initial term is a = 80 because x = 0 leads to y = 80.

We go from y = a*b^x to y = 80*2^x

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

You can use a tool like Desmos or GeoGebra to visually confirm each of the answers. Both also offer support for function tables.

Answer:

1.  y = -5x + 15.

2. y = -x + 4.

3. y = 80(2^(x/3))

Step-by-step explanation:

1.

From the given data, we can see that as x increases by 1, y decreases by a fixed amount of 5. This means that the relationship between x and y is linear, specifically a decreasing linear relationship.

To write the equation for a linear relationship, we need to find the slope (m) and y-intercept (b).

Using the formula for slope:

m = (change in y) / (change in x)

m = (0 - 30) / (3 - (-3))

m = -5

Using the point-slope form of a linear equation:

y - y1 = m(x - x1)

y - 30 = -5(x - (-3))

y - 30 = -5x - 15

y = -5x + 15

So the equation for this linear relationship is y = -5x + 15.

2.

From the given data, we can see that as x increases by 3, y decreases by a fixed amount of 3. This means that the relationship between x and y is linear, specifically a decreasing linear relationship.

To write the equation for a linear relationship, we need to find the slope (m) and y-intercept (b).

Using the formula for slope:

m = (change in y) / (change in x)

m = (-5 - 13) / (9 - (-9))

m = -18 / 18

m = -1

Using the point-slope form of a linear equation:

y - y1 = m(x - x1)

y - 13 = -1(x - (-9))

y - 13 = -1(x + 9)

y = -x + 4

So the equation for this linear relationship is y = -x + 4.

3.

From the given data, we can see that as x increases by 1, y doubles. This means that the relationship between x and y is exponential.

To write the equation for an exponential relationship, we can use the general form of an exponential function:

y = ab^x

where a is the initial value, b is the base, and x is the exponent.

To find a and b, we can use the first and fourth data points since they have the smallest and largest values of y, respectively.

When x = -3, y = 10, so we have:

10 = ab^(-3)

When x = 0, y = 80, so we have:

80 = ab^(0)

From the second equation, we can see that a = 80. Substituting this into the first equation, we get:

10 = 80b^(-3)

Simplifying, we get:

b = 2^(1/3)

So the equation for this exponential relationship is:

y = 80(2^(1/3))^x

Simplifying further:

y = 80(2^(x/3))

I replaced x as 2 in x2 - 4 = 0, 4x2 = 16, and 2(x-2)2 = 0 and they matched the result.

For the remaining equations that didn't match the result I replaced x with -2 and then they finally matched.

I replaced x as -2 in x2 = -4, and 3x2+12=0 and they matched the result.

If in any shape or form, I was incorrect please inform me and I'll attempt to resolve the issue and see my mistake, sorry if thi was wordy and long.

I hope this was helpful!

Answer:

Step-by-step explanation:

To determine if the graphs of two linear equations are parallel, we need to compare their slopes. If the slopes are equal, then the lines are parallel. If the slopes are not equal, then the lines are not parallel.

In case (a), the two equations are y = x + 3 and y = x + 6. Both equations have a slope of 1, which means the lines have the same steepness. However, the y-intercepts are different (3 and 6), which means the lines are shifted up or down relative to each other. Since the slopes are equal, but the y-intercepts are different, the lines are parallel.

In case (b), the two equations are y = 4x - 1 and y = 1 - 4x. Both equations have a slope of -4, which means the lines have the same steepness. However, the y-intercepts are different (-1 and 1), which means the lines are shifted up or down relative to each other. Since the slopes are equal, but the y-intercepts are different, the lines are not parallel.

In case (c), the two equations are y = 2x - 3 and y = -2x + 3. The slopes of the two equations are 2 and -2, which are negative reciprocals of each other. This means the lines are perpendicular, not parallel.

In case (d), the two equations are 3y = x - 12 and 6y = 2x + 12. We can rewrite these equations in slope-intercept form by solving for y. The first equation becomes y = (1/3)x - 4 and the second equation becomes y = (1/2)x + 2. The slopes of the two equations are 1/3 and 1/2, which are not equal. Therefore, the lines are not parallel.

Answer:

22. Parallel

23. Not parallel

24. Not parallel

25. Parallel

Step-by-step explanation:

The slope equation form of a line is

y = mx + b

where

m = slope

b = y-intercept

If two lines are parallel their slopes, the value of m will be the same, in slope-intercept form

Q22

y = x + 33 → slope = 1
y = x + 6 →  slope = 1

Slopes are the same with = 1
Hence  the lines are parallel

Q23
y = 2x - 3  →  slope m = 2
y = -2x + 3  →  slope m = -2
Slopes not equal hence not parallel

Q24
y = 4x - 1 →  slope = 4
y = 1 --4x or y = - 4x + 1  → slope = - 4  

Slopes are different, hence not parallel

Q25
3y = x - 12
6y = 2x + 12

Divide the first equation by 3
=> 3y/3 = x/3 - 12/3
=> y = x/3 -4    →   slope = 1/3

Divide the second equation by 6
6y/6 = 2x/6 + 12/6
y = x/3 + 2  →   slope = 1/3

Slopes are same, hence parallel

The value of x and y in the trapezium are 118 and 35 degrees respectively.

The diagram above is a trapezium. A trapezium is a quadrilateral with 4 sides.  The sum of all the four angles of the trapezium is equal to 360°.

A trapezium has two parallel sides and two non-parallel sides.

Therefore, let's find x and y as follows:

x = 180 - 62(supplementary angles)

x = 118 degrees

y = 180 - 145(supplementary angles)

y = 35 degrees

Therefore,

x = 118 degrees

y = 35 degrees
