If the same BLANK number is multiplied to each side of a true inequality, the inequality sign is reversed to make the resulting
Maurinko [17]
Answer: Negative
If the same negative number is multiplied to each side of a true inequality, then the inequality sign flips to make the new inequality true as well

Example:
Take 1 < 5 and multiply both sides by -2 and we get -2 > -10. The "less than" sign flips to "greater than" since -2 < -10 is false. The value of -10 is further to the left of -2 so -10 is smaller in value. The negative basically takes the complete opposite which is why the flip must happen.

This sign flip rule does not happen if you multiply both sides by a positive number.

What is the number of subsets of S= {1, 2, 3…10} that contain five element include 3 or 4 but not both?
Ivenika [448]

Answer:

140

Step-by-step explanation:

To construct a subset of S with said property, we have two choices, include 3 in the subset or include four in the subset. These events are mutually exclusive because 3 and 4 can not both be elements of the subset.

First, let's count the number of subsets that contain the element 3.

Any of such subsets has five elements, but since 3 is already an element, we only have to select four elements to complete it. The four elements must be different from 3 and 4 (3 cannot be selected twice and the condition does not allow to select 4), so there are eight elements to select from. The number of ways of doing this is {}_8C_4=70.

Now, let's count the number of subsets that contain the element 4.

4 is already an element thus we have to select other four elements . The four elements must be different from 3 and 4 (4 cannot be selected twice and the condition does not allow to select 3), so there are eight elements to select from, so this can be done in {}_8C_4=70 ways.

We conclude that there are 70+70=140 required subsets of S.

Express as a trinomial: (x 4)(x-2) 3x
kramer
If it is (x-4)(x-2)3x than the answer is 3x(x^2-4x-2x+8) = 3x(x^2-6x+8) = 3x^3 - 18x^2 + 24x


If it is (x+4)(x-2)3x than the answer is 3x(x^2+4x+2x+8) = 3x(x^2+6x+8) = 3x^3 + 18x^2 + 24x
