First step when finding the mean is to add all the values together
7 + -9 + 6 + -10 + -13 + -5
To make this easier, first add all the positive numbers 7 + 6 = 13
Then add (basically take away) the minus values one by one
13 - 9 = 4
4 - 10 = -6
-6 - 13 = -19
-19 - 5 = -24
Next step is to divide this total by the number of values there were
In this case, there were 6 values
-24 / 6 = -4
D. -4

Mean of the above set of numbers is D. -4

Mean is the average of the sum of the numbers.

add all the numbers : 7 + (-9) + 6 + (-10) + (-13) + (-5) = -24 
divide the sum by the count of numbers added: -24/6 = -4

Gekata [30.6K]

x=3 is your answer. This is because it only crosses the x-axis and this occurs at positive 3. y=3 on the other hand would be a horizontal line that only touches positive 3 on the y-axis.

Answer:

The answer to your question is The point (-3, 2) is not a solution

Step-by-step explanation:

Inequality

                                   - 4x - 10y < - 9

-point (-3, 2)

Process

1.- To solve this problem, just substitute the point in the inequality and simplify

a) Substitution

                                    -4(-3) - 10(2) < - 9

b) Simplification

                                    12 - 20 < - 9

c) Result

                                        - 8 < - 9
