closed dot is if the number is part of the solution so if it is equal to

 and

use open if it is not part of solution as in if it is greater than or less than

 so for your picture x greater or equal to -2 it would be a closed dot

Answer:

The answer to your question is below

Step-by-step explanation:

Use proportions to solve these problems

1)

             (6x - 6)/35 = (3x + 7)/24

Solve for x

             24(6x - 6) = 35(3x + 7)

Expand

             144x - 144 = 105x + 245

             144x - 105x = 144 + 245

                       39x = 389

                           x = 389/39

                           x = 9.97

2)             9 + x = 6 + 15

Solve for x

                     x = 21 - 9

                   x = 12

The mean, median, and mode of the five numbers 5,7,8,A,B are equal. Find all possible values of A+B
mario62 [17]

If the mean, median, and mode of the five numbers 5, 7, 8, A, and B are equal, the possible values of A+B are <u>20,</u> where A is <u>8</u>, and B is <u>12</u>.

<h3>What are the measures of central tendency?</h3>

The measures of central tendency include the mode, the median, and the mean.

Statistically, a central tendency is a typical value for a probability distribution.

The mode's value appears most often in a set of data values.  The median is the middle value of a dataset.  The mean represents the average.

To determine the possible values of A and B, we can start by finding the median value, which is the middle value in ascending order.

<h3>Data and Calculations:</h3>

Median (Middle value) = 8

Mode = 8

Total value = 40 (8 x 5)

A = 8

B = 12.

Mean = 8 (40/5)

Thus, if the mean, median, and mode of the five numbers 5, 7, 8, A, and B are equal, the possible values of A+B are <u>20,</u> where A is <u>8</u>, and B is <u>12</u>.

What is the equation of this line in slope-intercept form?
Usimov [2.4K]

Answer:

B

Step-by-step explanation:

Reminder: slope-intercept form is y=mx+b where m is the slope and b is the y intercept

There are two points given on the line: (-1, 2) and (1, -4)

First, find the slope

Reminder: slope is y2-y1/x2-x1

Substituting the numbers into the equation gives -4-(-2)/1-(-1) which would make m=-3

Now that the slope is found, we can use slope point form

Reminder: slope point form is y-y1=m(x-x1)

Substituting the numbers would give this equation:

y-2=-3(x-(-1))

Simplifying the equation would give y=-3x-1.
