Which equations are direct variations? SELECT ALL THAT APPLY.

y=−2x

y=x+4

y=3/4x

y=x

2. If y varies directly with x, and y = 12 when x = 4, what is y when x = -5?
options:

20

-15

-20

15

If I know it right then

After solving check to see if you need to simplify again. ... x +3x. 2 x +x−6. 2. 3. 4x−8. × x +x−6. 2 x +x−6. 2. Adding and Subtracting ... 3y. 2x 3 y4 2 to get. ​Step 3)​Multiply by to get. ​Step 4)​add. +. (for. 12y 3. 8x y3 ... This is read “y varies directly as x.

step-by-step explanation:

i'm pretty sure it would take 20 hours because it's half the men so you multiply the number of hours it takes by 2
