A family creates a budget to begin saving for a vacation. The amount the family has can be modeled by the function f ( w ) = 310 + 640 w , where w is the number of weeks since the family started saving. The function g ( w ) = 560 + 382 w describes the family's weekly expenses. Which function, S ( w ) , represents the family's total savings after paying the weekly expenses? S ( w ) = − 250 + 258 w S ( w ) = − − 250 + 258 w S ( w ) = − 250 + 1 , 022 w S ( w ) = − − 250 + 1 , 022 w S ( w ) = 870 + 258 w S ( w ) = 870 + 258 w S ( w ) = 870 + 1 , 022 w

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

2/3

step-by-step explanation:

f(x)=2/3x-8, which give g(x) the greatest value.
