F(2) is the same as (3x-7)(3x-7)
Answer:
Tuesday
Step-by-step explanation:
Let the days of the week be numbered 1–7, starting with Monday and ending with Sunday. Let <em>t</em> represent today. We can equate the number of skirts finished by Friday (day 5) with the ones finished by Sunday (day 7) at the lower rate. (days × (skirts/day) = skirts)
... (5-t)×5 = (7-t)×3
... 25 -5t = 21 -3t . . . . . eliminate parentheses
... 4 = 2t . . . . . . . . . . . . add 5t-21
... 2 = t . . . . . . . . . . . . . divide by 2
Day 2 corresponds to Tuesday.

<em>Check solution</em>
(5-2)·5 = 15 = (7-2)·3 skirts are being made.
"my answer i came up with is g(x)=1/3-(4/3)x
g(-3)=1/3-4/3(-3)
=1/3+4
=13/3 or 4 1/3" [you are correct]
"i came up with f(x)=3x-5
f(1)=3*1-5
=3-5
=-2" [you are correct]
