Plea i need tha answer ! what is the solution of the system? use the elimination method. {4x+2y=18 2x+3y=15

Multiply everything on the second equation by 2, and everything on the first one by -1.

Then you add the equations.

We substitute into the first equation (it could be the second) to find x:

Now, we substitute into the second equation (again, could be the first; just don't use the same equation in these 2 steps):

We are correct, so our answers should be:

step-by-step explanation:

f

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
