Yana is using an indirect method to prove that segment DE is not parallel to segment BC in the triangle ABC shown below: A trian

gle ABC is shown. D is a point on side AB and E is a point on side AC. Points D and E are joined using a straight line. The length of AD is equal to 4, the length of DB is equal to 5, the length of AE is equal to 6 and the length of EC is equal to 7. She starts with the assumption that segment DE is parallel to segment BC. Which inequality will she use to contradict the assumption? 4:9 ≠ 6:13 4:9 ≠ 6:7 4:13 ≠ 6:9 4:5 ≠ 6:13

Please see attached file for the triangle’s figure:

 

Going with the image attached, if DE is parallel to BC<span>
then
<span>4: (4 + 5) = 6 : (6 + 7).

Therefore, the inequality that she will use to contradict the assumption</span> is 4:9 ≠ 6:13</span>.

To add, a relation that holds between two values when they are different in mathematics is called an inequality. A is not equal to b also means the notation a ≠ b.

<span><span>

</span>Inequalities are governed by the following properties<span>:

Transitivity</span></span>
 Converse
 Addition and subtraction
 Multiplication and division
 Additive inverse
 Multiplicative inverse
<span>Applying a function to both sides</span>

Cos(2x) - 3cos(x) + 2= 0 ??
alexandr1967 [171]
Ignore above
your equation is 2(cosx)^2-3cosx+1=0
use quadratic formula to get results
you will end up with
cosx=1 or cosx=1/2
so, x=0 or x=pi/3

Do you prefer Thai food or chinese food. is the question baised
Ksenya-84 [330]
No, this would not be a biased question unless the people asked were all Thai people or all Chinese people. Then the information would be skewed because naturally, Chinese people would favor Chinese food and same for Thai.
