If 2x + 4y =
9 and -7x + 7y = 5 are true equations, what would be the value
of-5x + 11y?

Step-by-step explanation:

examples pls.how to use set builder form ? give some examples pls.how to use set builder form ? give some examples pls.Solve the following linear equation :-

5x+7y=-9 4x-11y=26Solve the following linear equation :-

5x+7y=-9 4x-11y=26

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
