The equation of the line that passes through the points (-8, 9) and (2, -6) is y = (-3 / 2)x - 3.Given two points (-8, 9) and (2, -6). We are supposed to find the equation of the line that passes through these two points.

We can find the equation of a line that passes through two given points, using the slope-intercept form of the equation of a line. The slope-intercept form of the equation of a line is given by, y = mx + b,Where m is the slope of the line and b is the y-intercept.To find the slope of the line passing through the given points, we can use the slope formula: m = (y2 - y1) / (x2 - x1).Here, x1 = -8, y1 = 9, x2 = 2 and y2 = -6.

Hence, we can substitute these values to find the slope.m = (-6 - 9) / (2 - (-8))m = (-6 - 9) / (2 + 8)m = -15 / 10m = -3 / 2Hence, the slope of the line passing through the points (-8, 9) and (2, -6) is -3 / 2.

Now, using the point-slope form of the equation of a line, we can find the equation of the line that passes through the point (-8, 9) and has a slope of -3 / 2.

The point-slope form of the equation of a line is given by,y - y1 = m(x - x1)Here, x1 = -8, y1 = 9 and m = -3 / 2.

Hence, we can substitute these values to find the equation of the line.y - 9 = (-3 / 2)(x - (-8))y - 9 = (-3 / 2)(x + 8)y - 9 = (-3 / 2)x - 12y = (-3 / 2)x - 12 + 9y = (-3 / 2)x - 3.

Therefore, the equation of the line that passes through the points (-8, 9) and (2, -6) is y = (-3 / 2)x - 3. Thus, the answer is (-3/2)x - 3.

Answer:

\(\frac{11}{15} \)

Step-by-step explanation:

\(\frac{1}{3} \) + \(\frac{2}{5} \)

The least common multiple of 3 and 5 is 15. Convert \(\frac{1}{3} \) and \(\frac{2}{5} \) to fractions with denominator 15.

\(\frac{5}{15} \) + \(\frac{6}{15} \)

Since \(\frac{5}{15} \) and \(\frac{6}{15} \) have the same denominator, add them by adding their numerators.

\(\frac{5+6}{15} \)

Add 5 and 6 to get 11.

Answer: 38%

Step-by-step explanation: First, we subtract $8.50 from $13.50 to get the discount of $5. Then divide this by the original price to get 0.38 (rounded). Multiply this by 100, and we get 38, which means Shannon received a 38% discount. If this is wrong, it will be 37% because the number I rounded to get 0.38 was originally 0.37037037 repeating.

Answer:

37%

Step-by-step explanation:

To find what is the percent of the discount she receive we have to use an formula;

Discount Formula: (Original price - Discounted price) / Original price x 100

Using the formula we can find the answer.

Knowing that;

Original price: 13.50

Discounted price: 8.50

Thus,

13.50 - 8.50 / 13.50 x 100

= 37.037037037

Round - 37%

As a result, Shannon received a 37% discount.

The relation R on the set of ordered pairs of positive integers (a, b) ∈ Z* x 7+ is defined as R = {(a, b) | ad = bc}.

The relation R on the set of ordered pairs of positive integers is defined as follows:

R = {(a, b) ∈ Z* x 7+ | ad = bc}

In this relation, (a, b) is related to (c, d) if and only if their products are equal, i.e., ad = bc.

For example, (2, 3) R (4, 6) because 2 * 6 = 4 * 3.

This relation represents a proportional relationship between the ordered pairs, where the product of the first element of one pair is equal to the product of the second element of the other pair.

Step-by-step explanation:

If two points are at different heights on a graph, we would need to check the values of the dependent variable (y-axis) to establish if they are actually different.

To establish if two points on a graph at different heights are actually different, we should check the values of the dependent variable (y-axis) being plotted

We should check the numerical values of the variable being plotted on the y-axis to see if they are different between the two points. This would tell us whether there is a statistically significant difference between the two groups or not.

To determine whether the difference between the two points is statistically significant, we can perform a hypothesis test or a statistical analysis to compare the means or distributions of the data at the two points.

Alternatively, we can also look at confidence intervals or p-values to establish the statistical significance of the difference between the two points.

Answer:

v=-1

Step-by-Step Explanation:

Answer:

\(v=-1\)

Step-by-step explanation:

\(6\left(6v+6\right)-5=1+6v\)

Use the distributive property to multiply 6 by 6v+6:

\(36v+36-5=1+6v\)

Subtract 5 from 36 = 31

\(36v+31=1+6v\)

Subtract 6v from both sides:

\(36v+31-6v=1\)

Combine like terms:

\(36v\) and \(-6v\) \(=30v\)

\(30v+31=1\)

Subtract 31 from both sides:

\(30v=-30\)

Divide both sides by 30:

\(\cfrac{30v}{30}=\cfrac{-30}{30}\)

Step-by-step explanation:

The area of the regular polygons with 12 sides(dodecagon) and 5 sides (pentagon) are 389.06 in² and 19.87 in² respectively.

Area of regular polygon = 1/2 × apothem × perimeter

perimeter = (s)side length of octagon × (n)number of side.

apothem = s/[2tan(180/n)].

11 = s/[2tan(180/12)]

s = 11 × 2tan15

s = 5.8949

perimeter = 5.8949 × 12 = 70.7388

Area of dodecagon = 1/2 × 11 × 70.7388

Area of dodecagon = 389.0634 in²

Area of pentagon = 1/2 × 5.23 × 7.6

Area of pentagon = 19.874 in²

Therefore, the area of the regular polygons with 12 sides(dodecagon) and 5 sides (pentagon) are 389.06 in² and 19.87 in² respectively.

Answer:

12 cubic meters

Step-by-step explanation:

The value of x is equal to 15°

In Mathematics and Geometry, the sum of the exterior angles of both a regular and irregular polygon is always equal to 360 degrees.

Note: The given geometric figure (regular polygon) represents a pentagon and it has 5 sides.

By substituting the given parameters, we have the following:

3x + 4x + 8 + 5x + 5 + 6x - 1 + 5x + 3 = 360°.

3x + 4x + 5x + 6x + 5x + 8 + 5 - 1 + 3 = 360°.

23x + 15 = 360°.

23x = 360 - 15

23x = 345

x = 345/23

x = 15°.

The correct answer is b) 1.397. The value of t, the critical value of the t distribution with 8 degrees of freedom, which satisfies the condition that the probability is 0.10 of being larger than t, can be found using a t-distribution table or statistical software.

By referring to a t-distribution table or using statistical software, we can determine that the critical value with 8 degrees of freedom and a probability of 0.10 of being larger than t is approximately 1.397.

Thus, the correct answer is b) 1.397. This value is important because it allows us to make inferences about the population based on sample data, particularly when the population's standard deviation is unknown. The t distribution becomes increasingly similar to the standard normal distribution as the degrees of freedom increase. In this specific case, the critical value of 1.397 can be used to conduct hypothesis tests or construct confidence intervals when working with a sample size of 9 (8 degrees of freedom = sample size - 1) and a significance level of 0.10.

Answer:

Point C is the closest to the y-axis

Step-by-step explanation:

If the coordinates of a point Z is (x,y), it means that point Z is x units from the x axis and Y units from the y axis.

The coordinates of point A are (3, –3). The coordinates of point B are (1, –3). The coordinates of point C are (–2, 2).

Since coordinates of point A are (3, –3), point A is 3 units from the x axis and 3 units from the y axis.

Since coordinates of point B are (1, –3), point B is 1 units from the x axis and 3 units from the y axis.

Since coordinates of point C are (-2, 2), point C is 2 units from the x axis and 2 units from the y axis.

Therefore, Point C is the closest to the y-axis
