So I have some confusion and I'm having a hard time following the logic of how you convert a linear equation from slope intercept form to standard form.

Here is an example

How is it when you are converting from slope intercept form to standard form:

1.) When you are subtracting 3x from both sides in this example, I could see that both 3xs cancel out but I'm confused about how you can subtract it from y ( a different variable) and also end up with 3x on the side underneath y (How do they switch places)

2.) Also how does the variable y end up right next to -3x? Also, how is 3x negative? is it just dragged down or something?

There are no two Real numbers that add up to -2 and multiply to 10.

The numbers that add up to -2 and multiply to 10, we can use algebraic methods. Let's denote the two numbers as x and y. Based on the given conditions, we can set up two equations:

Equation 1: x + y = -2

Equation 2: x * y = 10

To solve this system of equations, we can use substitution or elimination methods. Let's solve it using the substitution method:

1. Solve Equation 1 for x:

  x = -2 - y

2. Substitute the value of x in Equation 2:

  (-2 - y) * y = 10

3. Simplify the equation:

  -2y - y^2 = 10

4. Rearrange the equation to standard form:

  y^2 + 2y + 10 = 0

5. Since the equation is a quadratic equation, we can apply the quadratic formula:

  y = (-b ± √(b^2 - 4ac)) / (2a)

  In this case, a = 1, b = 2, and c = 10.

6. Calculate the discriminant: b^2 - 4ac:

  2^2 - 4(1)(10) = 4 - 40 = -36

7. Since the discriminant is negative, the quadratic equation does not have real solutions. Therefore, there are no real numbers that satisfy both conditions of adding up to -2 and multiplying to 10.

In conclusion, there are no two real numbers that add up to -2 and multiply to 10.

Answer:Your answer is 106

Step-by-step explanation:

The height of the television transmission tower is approximately 1298 feet.

The height of the television transmission tower, we can use trigonometry and the concept of tangent.

Let's denote the height of the tower as h.

We know the length of the shadow is 1130 feet and the angle formed by the ground and the line from the top of the tower to the tip of the shadow is 48.3 degrees.

The tangent of an angle is defined as the ratio of the opposite side to the adjacent side.

The height of the tower is the opposite side and the length of the shadow is the adjacent side.

Using the tangent function, we can set up the following equation:

tan(48.3°) = h / 1130

To solve for h, we can multiply both sides of the equation by 1130:

1130 × tan(48.3°) = h

Using a calculator, we find:

h ≈ 1130 × 1.1477

Step-by-step explanation:

There are 8 outcomes.  Three have exactly two tails.  

There is no day when the Number of cupcakes sold at Location 1 is equal to the number of cupcakes sold at Location 2. on Day 5, Location 2 sold 850 cupcakes.

(a) To determine the number of cupcakes sold at each location on Day 5, we substitute x = 5 into the equations:

For Location 1:

y = 150x + 200

y = 150(5) + 200

y = 750 + 200

y = 950

Therefore, on Day 5, Location 1 sold 950 cupcakes.

For Location 2:

y = 150x + 100

y = 150(5) + 100

y = 750 + 100

y = 850

Therefore, on Day 5, Location 2 sold 850 cupcakes.

(b) To find the day when the number of cupcakes sold at Location 1 is equal to the number of cupcakes sold at Location 2, we set the two equations equal to each other:

150x + 200 = 150x + 100

We can see that the variable x cancels out, which means the value of x doesn't matter in this case. The equation simplifies to:

200 = 100

However, this equation is not true. It implies that the number of cupcakes sold at Location 1 can never be equal to the number of cupcakes sold at Location 2.

Therefore, there is no day when the number of cupcakes sold at Location 1 is equal to the number of cupcakes sold at Location 2.

The calculated area of the composite figure is 85 cm².

From the question, we have the following parameters that can be used in our computation:

The composite figure (see attachment)

Where, we have

Rectangle:

Area = length × width.

Therefore, the area of the rectangle is 10 cm × 6 cm = 60 cm².

Triangle:

Area = (1/2) × base × height.

Therefore, the area of the triangle is (1/2) × 5 cm × 10 cm = 25 cm².

To find the total area of the composite figure, we add the areas of the rectangle and the triangle:

Total Area = Area of Rectangle + Area of Triangle

Answer:  x=72

Step-by-step explanation:

All of the angles of a triangle add up to 180

32+x+x=180             >combine x's

32+2x=180              >subtract 32 from both sides

2x=148                    >Divide both sides by 2

x=74

Answer:

Step-by-step explanation:

We know that,

sum of 3 side of triangle is 180°

So,

→ 32° + x + x = 180°

→ 32° + 2x = 180°

→ 2x = 180° -32°

→2x = 148

→ x = 148/2

→ x = 74

Thus, x = 74°

To find the zeroes of the polynomial 2 + 2√2x - 6, we set the polynomial equal to zero and solve for x:

2 + 2√2x - 6 = 0

Rearranging the terms:

2√2x = 4

Dividing both sides by 2√2:

x = 2/√2

To simplify the expression, we rationalize the denominator:

x = (2/√2) * (√2/√2) = 2√2/2 = √2

Therefore, the zero of the polynomial is x = √2.

To verify the relationship between the zeroes and coefficients of the polynomial, we can use Vieta's formulas. For a quadratic polynomial in the form ax^2 + bx + c = 0, the sum of the zeroes is given by -b/a and the product of the zeroes is given by c/a.

In this case, the polynomial 2 + 2√2x - 6 is not a quadratic polynomial, but rather a linear one. However, we can still apply Vieta's formulas:

The sum of the zeroes is -b/a = -(2√2)/1 = -2√2.

The product of the zeroes is c/a = (-6)/1 = -6.

Therefore, the relationship between the zeroes (√2) and the coefficients (2, 2√2, -6) is that the sum of the zeroes (-2√2) is equal to the negation of the coefficient of the linear term, and the product of the zeroes (-6) is equal to the constant term of the polynomial.

Step-by-step explanation:

Let's assume that the total cost of membership after "m" months for club A is "T(A)" and the total cost of membership after "m" months for club B is "T(B)".

For club A, the total cost of membership after "m" months is given by:

T(A) = 17 + 29m

For club B, the total cost of membership after "m" months is given by:

T(B) = 11 + 30m

To find the number of months when the total cost is the same for both clubs, we need to solve for "m" in the equation:

T(A) = T(B)

Substituting the expressions for T(A) and T(B), we get:

17 + 29m = 11 + 30m

Simplifying and solving for "m", we get:

m = 6

Therefore, the total cost of membership will be the same for both clubs after 6 months. After that point, Club A will be more expensive due to its higher monthly fee.

D: 18i + 8b ≤ 100

Step-by-step explanation:

The correct inequality that represents the scenario is option D: 18i + 8b ≤ 100.

Explanation:

Let's break down the components of the inequality based on the given information:

8i represents the cost of ink bottles (i) at $8 each.

8b represents the cost of brushes (b) at $18 each.

18i + 8b represents the total cost of ink bottles and brushes combined.

The scenario states that Emily has $100 extra to spend, which means the total cost of ink bottles and brushes should be less than or equal to $100. Therefore, the correct inequality is 18i + 8b ≤ 100.

The duration during which the height of the ball is increasing is from 1 second to 2.4 seconds.

To determine the duration during which the height of the ball is increasing, we need to analyze the given data points.

At 0.5 seconds, the height is 27 units.

At 1 second, the height is 31 units.

At 2.4 seconds, the height is 2 units.

We can observe that the height is decreasing between 0.5 seconds and 1 second because the height decreases from 27 to 31. This indicates that the ball is descending during that time interval.

However, between 1 second and 2.4 seconds, the height is increasing because the height goes from 31 to 2 units. This implies that the ball is ascending during that time interval.

Therefore, the duration during which the height of the ball is increasing is from 1 second to 2.4 seconds.

I remember doing this in 8th grade, this was genuinely fun.

Anyways,

To create an accurate and logical layout of the water park attractions, we can use ordered pairs to represent the location of each attraction. Assuming that the water park is laid out on a rectangular grid, we can use (x, y) coordinates to represent the location of each attraction, where x represents the horizontal position and y represents the vertical position.

Here are some possible ordered pairs that could represent the location of the attractions in the water park:

Help Center: (0,0)

Large Whirlpool: (10,10)

Water Slide #1: (5,20)

Water Slide #2: (15,20)

Water Slide #3: (10,30)

Toddler Area: (20,0)

Lazy River: (30,15)

Concessions: (25,30)

Of course, the actual layout of the water park will depend on various factors such as the size and shape of the park, the available space, and the specific design of each attraction. These ordered pairs are just one example of how the attractions could be laid out on a rectangular grid.

PART 2:

Sure, I can help you with that too. Here's how you can calculate the slope between attractions using the slope formula:

The slope formula is:

m = (y2 - y1)/(x2 - x1)

where m is the slope of the line connecting two points (x1, y1) and (x2, y2).

For example, to calculate the slope between the Help Center and the Large Whirlpool, we can use the ordered pairs (0,0) and (25,25):

m = (25 - 0)/(25 - 0) = 1

Therefore, the slope between the Help Center and the Large Whirlpool is 1.

Similarly, we can calculate the slopes between each pair of attractions using their respective ordered pairs.

To find the midpoint between two attractions, we can use the midpoint formula:

Midpoint formula: ((x1 + x2)/2, (y1 + y2)/2)

For example, to find the midpoint between the Help Center and the Large Whirlpool, we can use the ordered pairs (0,0) and (25,25):

((0 + 25)/2, (0 + 25)/2) = (12.5,12.5)

Therefore, the midpoint between the Help Center and the Large Whirlpool is (12.5,12.5).

Once you have the slope and midpoint for each pair of attractions, you can use them to writethe linear equations for the lines connecting the attractions. The point-slope form of a linear equation is:

y - y1 = m(x - x1)

where m is the slope of the line and (x1, y1) is a point on the line.

For example, to write the linear equation for the line connecting the Help Center and the Large Whirlpool, we can use the slope of 1 and the midpoint of (12.5,12.5):

y - 12.5 = 1(x - 12.5)

Simplifying this equation, we get:

y = x

Therefore, the linear equation for the line connecting the Help Center and the Large Whirlpool is y = x.

Similarly, we can write the linear equations for the lines connecting each pair of attractions using their respective slopes and midpoints.

Approximately 99.7% of housing prices are between a low price of $101,000 and a high price of $149,000.

Step-by-step explanation:

To complete the statement using the empirical rule, we need to determine the range within which approximately 99.7% of housing prices fall.

According to the empirical rule, for a normal distribution:

Approximately 68% of the data falls within one standard deviation of the mean.

Approximately 95% of the data falls within two standard deviations of the mean.

Approximately 99.7% of the data falls within three standard deviations of the mean.

Given that the mean housing price is $125,000 and the standard deviation is $8,000, we can apply these percentages to calculate the range:

One standard deviation:

The low price would be the mean minus one standard deviation:

$125,000 - $8,000 = $117,000

The high price would be the mean plus one standard deviation:

$125,000 + $8,000 = $133,000

So, approximately 68% of housing prices fall between $117,000 and $133,000.

Two standard deviations:

The low price would be the mean minus two standard deviations:

$125,000 - 2 * $8,000 = $109,000

The high price would be the mean plus two standard deviations:

$125,000 + 2 * $8,000 = $141,000

So, approximately 95% of housing prices fall between $109,000 and $141,000.

Three standard deviations:

The low price would be the mean minus three standard deviations:

$125,000 - 3 * $8,000 = $101,000

The high price would be the mean plus three standard deviations:

$125,000 + 3 * $8,000 = $149,000

So, approximately 99.7% of housing prices fall between $101,000 and $149,000.

In conclusion, approximately 99.7% of housing prices are between a low price of $101,000 and a high price of $149,000.
