Parsons bank offers two checking account plans. the no frills plan charges 50 cents per check whereas the simple checking plan costs $6 per month plus 25 cents per check. for what number of checks per month will the simple checking plan cost less?

the answer will be

f is the midpoint of

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
