An artist can make two kinds of ornaments, free standing or hanging. He can make at most 50 ornaments each week, and the greatest number of hours he can work in a week is 70. It takes 2 hours to make a free standing ornament and 1 hour to make a hanging ornament. His profit is $9 for each free standing ornament and $12 for each hanging ornament. How many of each type ornament should he make to maximize his profit

y=−9/2x+10

step-by-step explanation:

let's solve for y.

0−9x−2y=−20

step 1: add 9x to both sides.

−9x−2y+9x=−20+9x

−2y=9x−20

step 2: divide both sides by -2.

−2y

−2

=

9x−20

−2

y=

step-by-step explanation:

sas (side angle side)

aa (angle angle)

sss(side side side)

sas find two sides with an angle in between

aa is finding two angles and the third will add up to 180

sss find all sides
