13. linear functions alwasys have x^1 as highest exonent for placeholder
we see that in D, we have 6x^2 which is quadratic, not linear

D is ansre

15. isolate y
emember you can do anything to an equaiton as long as you do it to both sides

12x-4y=20
add 4y to both sides
12x+4y-4y=20+4y
12x+0=4y+20
12x=4y+20
minus 20 both sides
12x-20=4y+20-20
12x-20=4y+0
12x-20=4y
divide both sides by 4
12/4x-20/4=4/4y
3x-5=1y
3x-5=y
y=3x-5
why is it not listed, there is an error in the question, report the erre

Shelia mixed 3 ounces of blue paint with 2 ounces of yellow paint. She decided to create 20 ounces of the same mixture. How many
zimovet [89]
Yellow:blue is a ratio of 2:3, meaning that 2/5 of the desired mixture is yellow. From this, you need to find how much yellow is necessary for 20 ounces. Well, 2/5 of the 20 ounces will be yellow paint, while the other 3/5 will be blue. So she will need 8 ounces of yellow paint to get 20 ounces of the desired mixture. Hope this helps! :)
