Some one say that if you multiply or divide each side of an inequality by a negative number, the inequality sign changes directions. He give an example: -2x < 6, then x > -3. Is the statement true or false?

True

Step-by-step explanation:

Step-by-step explanation:

It is true!

Let's say we subtract 6 from both sides

-2x -6< 0                       Now Let's add 2x to both sides

-2x + 2x - 6 < 0 + 2x

- 6 < 2x                         We did so we would be dividing by a number greater than 0.                         Divide by + 2

-6/2 < 2x / 2

-3 < x                            Notice you still get the open end of the inequality sign closest to the x without changing the direction of the inequality.

step-by-step explanation:

given that there are two triangles j'k'l' and jkl>

the former is got by dilating the second one.

when drawn on a grid, (graph paper) coordinates of vertices of first triangle is

(6,12)j, (9,6)k and (12,9)l

side jk has length = distance between j and k

=

side j'k'=distance between j' and k'

=

ie j'k'l' has sides 1/3 of that of corresponding sides of jkl.

hence scale factor of 1/3 is used to get j'k'l'from jkl
